Hey Jefferson,
You need to setup the height via CSS. Inline or using the Element CSS. See https://youtu.be/MMeOS2kNtOI. In the screencast, you’ll see that you can cover the section with an Image element also. You just have to disable the Row’s Inner Container option and ensure there are no paddings in your section and row. This is mostly used when you want to show all the parts of your image and you have nothing else to add in your section. If you’re going to put elements on top of your image or want a fullscreen effect, you need to use it as a background. Just note that certain parts of your image will be hidden because your section will have different aspect ratios when viewed on different screen sizes and your image has a fixed aspect ratio. With that said, using the image as a background is not good if you have important information to show in your image.
Here’s the code to be inserted in the section’s Element CSS
$el {
height:100vh
}
Hope that helps.
