As of Pro v4.0.0, X v8.0.0, and Cornerstone v5.0.0, all v2 Elements within the builders include a brand new Effects module, which allows users to take advantage of the CSS properties
transform (along with a few other goodies). Additionally, these properties can be transitioned on interaction as well as during scroll events. This powerful new group of controls unlocks a completely new toolset for designers and developers to leverage in their builds.
You can locate the Effects module as a top-level control group on any Element you're currently inspecting, like so:
Clicking on that top-level control group will reveal the following set of controls:
From here you will see the four main control groups within the Effects module: Base, Interaction, Scroll, and Specialty. The Base control group allows you to set static effects on your Element that serve as a foundation that either doesn't change at all, or might act as a starting point for another interactive or scroll effect to play off of. Interaction and Scroll are both opt-in groups, which can be enabled via the toggle next to their headings. Finally, the Specialty control group contains additional static controls that are more experimental and should be utilized with a certain degree of caution (more on this later).
Let's kick things off with the foundational controls:
As mentioned previously, the three main CSS properties that we are working with in the Effects module is
transform. If you are unfamiliar with any of these properties, below is a brief description of each:
opacity– Allows you to specify a variable transparency on the Element.
filter– Enables the use of visual effects such as blurring, grayscale, hue rotation, et cetera.
transform– Alters the appearance of the Element without changing it's physical placement. Can be used to move, skew, and rotate Elements.
The Opacity control is relatively straightforward, so let's jump ahead to Filter. Clicking on that control will reveal the following popup:
The nice thing about the Effects module is that the more complex aspects of it will feature a guided interface to help you along, even if you are unfamiliar with that particular CSS property. From the screenshot above, you can see that you can just jump in and start typing the property value in the input if you wish, or you can click the + button to add a "layer" to this property and see the guided interface:
In the screenshot above we've selected the
blur() function for our Filter control, which presents you with a slider you can use to adjust the value. All of this is composed for you by default and output to the input below. Now, let's say that you wanted to add a second filter:
For this layer we've chosen the
hue-rotate() function, which features a relevant slider just like before. Note that since this layer is second in the list, it is output as the second value in the input below. This is a very important piece of information to keep in mind: filters—and transforms—are linear in their output. What this effectively means is that the order you place them in matters and will give you different results in some scenarios.
If you wanted to move the
hue-rotate() function to the first position in your output you could copy and paste it in the input below, but the easier way to do this would be to grab the layer in the list above and drag it to the first position:
Once it is dropped, you will notice that the
hue-rotate() function has been moved to the first slot on the list as well as the input below. This allows you to quickly experiment with different orders and see how it affects the overall output of your effect:
Now that we're a little more familiar with this guided process for the Filter control, let's jump to the Transform control:
You will notice a similar interface like what we saw above with the Filter control. Just as in that context, clicking the + button will reveal our guided settings for the Transform control:
In this interface you will be able to experiment with “moving” (translating), skewing, and rotating your Element, as well as the order of these transforms.
The final control in the base control group is the Transition control. Clicking on that picker will reveal the following popup:
You can use these controls to set the general
transition-timing-function of your Elements. These values will be applied to not only the Effects transitions of the Element, but also that Element's colors, shadows, graphics, particles, et cetera. These values are used for the transition between the base and interaction styles of your Element.
All Elements have a default value for both of these settings. For the vast majority of them, the default Duration is 300ms and the default Easing is Material Standard. If these values are not changed, no dynamic CSS will be output as they are handled by the static stylesheets of the theme, which keeps your generated styles as lean as possible.
Next, let's move to the Interaction group, which features a near identical set of controls. The primary difference here is the Type selection as well as the Transition control:
Type allows you to choose between utilizing a Transform or a pre-baked Animation when interacting with the Element. There are a couple things to keep in mind with the one you choose (and how you have your base controls set):
- Transform – Selecting this option will allow you to create an additive transform that builds on any transforms set in the Base control group. For example, say you set a
skew()in your Base group and on hover you wanted it to keep that
translate()up some, you could use this control to do that and the transition would be smooth between the two.
- Animation – The animations available in the Effects module are based on animate.css. Because many of these animations are built using their own transforms, you typically will not be able to use these in conjunction with a Base transform. Practically, this means if you want to use an animation on interaction (or scroll), it is recommended that you leave your base Transform control blank. You can however still utilze base / interaction
filterin conjunction with these animations though.
When selecting Animation, the Transform control will be replaced with a dropdown allowing you to select the desired effect:
Additionally, you will notice that an Animation Transition control appears as well. This allows you to specify the timing of the animation only on your Element. This can stack with the Transition control in the base control group, meaning that you could set a value on that control to manage the transition between colors and opacity and filters, but then have an entirely different duration for your interaction animation...lots of options to explore!
Finally, let's review the Scroll control group:
This control group might look like there is a lot more going on, but you'll notice that we have a lot of the same repeated controls from before. The main difference here is that we have two variants of each CSS effect—an “In” and an “Out” style. The “In“ style is what is used when the Element comes into view and the “Out“ style fires as the Element leaves the viewport.
For example, if you wanted to create a simple fade-in transition with the Element translating from the side as you scroll to it, you could do the following:
- Out –
- In –
This would push your element to the right a bit and have it faded out, and then as you scroll to it, it would translate back to its original position and fade into view. This is just one very simple exmaple of what you can do with the scroll controls. Once you start pairing this with filters and changing the offsets and behavior…the options are near limitless.
Alternately, just as in the Interaction control group, you can select Animation as the type and use pre-built animations instead, which is great if you don't need as much fine-tuned control and just want to get something up and running:
As with the Interaction control group, if using the Animation option here, it is recommended that you do not have any Base or Interaction Transform controls in use to avoid potential styling conflicts.
After you have your effect setup, you'll want to ensure that your Behavior is set how you want it. The available options do the following:
- Once – Your Element will instantiate with the “Out” style and fire one time once it has come into view, ending with the “In” styles.
- Reset – Your Element will instantiate with the “Out” style and transition to the “In” styles when you scroll down to it, and it will remain in that state until you scroll back above it where it will reset back to the “Out” style. It will retrigger each time you scroll down to it.
- In-Out – Your Element will instantiate with the “Out” style and transition to the “In” styles when it comes into view, then transition back to the “Out” styles as it leaves the viewport again. It will keep retriggering at the top and bottom of the viewport each time it enters and leaves.
The Offset control can be set using % or px units with % values being based off the viewport height. For example, if you set your Top and Bottom values to
10% each, your Element styles would be triggered when
10% away from the top and bottom edges of the viewport respectively. Alternately, if you utilized
50px each, the styles would be triggered when
50px away from the top and bottom edges of the viewport respectively.
Finally, Transition is used to set the timing of the scroll effect. The primary difference here is the presence of a Delay control, which can allow you to stagger Elements as they enter and exit with your scrolling effects.
Specialty: Mix Blend Mode
In addition to the properties mentioned above, there is also a Mix Blend Mode control in the Specialty control group. This particular control is completely static and does not have an alternate setting in the Interaction or Scroll control groups. If you are unfamiliar with the
mix-blend-mode CSS property, we strongly recommend that you learn more about it to understand it more fully.
mix-blend-mode CSS property sets how an element's content should blend with the content of the Element's parent and the Element's background. To see some examples in action, let's take the following situation:
The above screenshot is a Row Element with no gap and two Columns, both set to have the same background color Yes, we promise there are two even though you can't see it—we're not messing with you. 😊
Now, we're going to add an Image Element to the first Column and set its
100% and its
200%, forcing it to span the entire length of the Row:
So our Image Element is physically only in the first Column but visually spanning both Columns. This will allow us to see how changing the value of the Mix Blend Mode control affects one half of the image while the other half remains the same. For instance, here is the Darken setting:
The following is a demonstration of Color Burn:
Here is Exclusion:
And finally, Luminosity:
Keep in mind that these are only four examples out of a very large list of selections, including:
In addition to the MDN resource linked above, we would also recommend checking out this CSS-Tricks article, which features many great examples of
mix-blend-mode in action in addition to exaplaining the various property values.
mix-blend-mode is not supported in IE11. Because of this, we recommend using it as more of a progressive enhancement in your designs.
Specialty: Backdrop Filter
Another item found in the Specialty control group is the Backdrop Filter control. This particular control is completely static and does not have an alternate setting in the Interaction or Scroll control groups. If you are unfamiliar with the
backdrop-filter CSS property, we strongly recommend that you learn more about it to understand it more fully.
backdrop-filter property lets you apply graphical effects such as blurring or color shifting to the area behind an Element. Because it applies to everything behind the Element, to see the effect you must make the Element or its background at least partially transparent.
So let's see a simple example of what is possible using
backdrop-filter. Take the common example of placing a Button as a call-to-action within a Section that has a hero background image:
For this particular example I've applied a slight transparent background to the Button. Because of how busy the image is behind Button, the text inside the Button is getting lost in the noise a little bit. Now, we could lower the contrast on our background image or reduce the transparency of the background color on our Button, but let's see what applying a
backdrop-filter can do:
In the image above, we've applied
blur(10px) to the
backdrop-filter of our Button. Notice how this single change has helped to separate the content of the button away from the background of the Section. The neat thing about
blur() is that we can still see the general form of the image behind our content (e.g. take note of the diagonal line of the table), just in a more abstract way. Now let's try a different filter with
Again, notice how the simple reduction in contrast of the colors behind our Button helps to offset it from the background. Now, let's try something a little different with the
For this particular example, while the color shift of the background colors is interesting, I wouldn't say that it has helped to offset our content much. In this particular example we are just using
hue-rotate(-50deg). The neat thing about
backdrop-filter though is that similar to
filter, you can stack multiple functions to create intricate effects:
In the image above we're using the following chain of functions:
blur(10px) contrast(75%) hue-rotate(180deg). Notice how this particular combination of functions allows us to add subtle depth and detail to our design. This is just one very simple example of what is possible when using
backdrop-filter, but there is so much more to explore in your designs!
backdrop-filter is not supported in IE11 and has to be enabled by users in Firefox. Because of this, we recommend using it as more of a progressive enhancement in your designs.
Link Child Interactions
One final item to discuss is the Link Child Interactions control group. This particular control group is only present on structural Elements—Section, Rows, Columns, Grids, Cells, and Divs:
This control allows you to chain child Element transitions based on interactions occurring on their parent. For example, let's say that you have a linked Column you've created and you want all Elements inside of it to go to their interaction state when you hover over the Column. To do this, you would turn on the Link Child Interactions control on that Column and by simply doing this all "interactive" Elements inside that Column will change when hovering over the Column Element.
The really cool thing about this though is that you can breakout which pieces of the child Elements should be triggered when hovering over the Column using the selection control seen above:
- Colors: if this option is selected, hovering over the interaction provider Element will trigger all nested Elements that have an "interaction" color to transition to that color.
- Particles: if this option is selected, any nested Element with a Particle will have that Particle trigger to its interactive state when hovering over the interaction provider. Particles are present on all structural Elements and Buttons.
- Effects: if this option is selected, any nested Element that has an interactive effect style will have that triggered when hovering over the provider. This means explicit effects created with the Effects Module (e.g.
transform) as well as prefabricated Effects, such as transitions on the graphics found inside Buttons and Headlines.
The very powerful thing about this interaction provider is that you can mix and match any of these targets. For example, you might have a linked Column with a Button inside it and that Button might have some color transitions as well as an Effect added (let's say that it translates up slightly). If you only enabled Colors on your interaction provider, that would mean hovering over the Column would trigger the color change on your Button, but the Effect transition would not take place until you hover directly over the Button...this is only scratching the surface of what is possible using the interaction provider!
Putting it All Together
All of the facets of the Effects module are stackable and able to be combined with a few minor caveats to keep in mind:
- Do not combine transforms and animations.
Keyframe animations have their own easing timeline they operate in and if a
transformis defined for that animation it will overwrite your base value while that timeline is running. For example, if you set a static
transformwith a rotation and then use an animation for your interactive style that defines a transform without that exact same starting and ending rotation, you will end up seeing a "flicker" as the transforms applied to your Element jump between the static and animated variants. TL;DR if you wish to use the pre-built animations in the Effects module, do not set a static
transformand use an animation for any interaction and scroll styles you opt into.
filtercan (almost always) be used additively.
While you should not combine the transition types mentioned above,
filtervalues can often be introduced additively to transforms and animations. For example, you may choose to enable your Scroll control group and set your “In” animation to Roll In and your “Out” animation to Roll Out. This particular animation sets an
transformtimeline up within its definition, but you could add a
filteron top of this to enhance it—you might add
blur(5px)to your “Out”
blur(0px)to your “In”
filter, which would introduce the appearance of the object coming in and out of focus.
- Filters are fun, but use them with caution.
filterproperty has opened up lots of fun and exciting new design possibilities within the browser, particularly using functions like
grayscale(), and more to alter the appearance of our markup within the browser. That being said, be aware that not all browsers treat filters with equal performance and certain elements should likely avoid using filters at all. For example, you can do things like apply a
grayscale()filter to a video in the browser to alter its appearance, but doing so will cause some browsers to spike in CPU usage and can bring your site to a halt. Use these functions with awareness and always make sure to test anything you're doing in multiple browsers.
- Mix Blend Mode and Backdrop Filters are fun, but use them with caution.
Pretty much for the exact same reasons as the previous bullet point.
