To transform photo captions in to lower case, please add the following code in your Customizer via Appearance > Customize > Custom > CSS:

.h-entry-cover{
    text-transform: lowercase;
}

In case you want to capitalize first letter of the sentence, please add the following:

.h-entry-cover:first-letter{
text-transform: capitalize
}

Hope this helps.
Thanks.

Thanks.

To make the image caption capitalize, add this under Custom > CSS in the Customizer.

.wp-caption-text {text-transform: capitalize !important;}

Cheers!

IN my case, I would like to have full control over all the letter cases in the captions. ie, your latest code makes every word in the caption capitalized but I would like to be able to control all the letters and make them fully case-sensitive

In other words, I would like to make the caption exactly as I type it in the caption box for each photo.

Example:
“This is an EXAMPLE of how I would like my CAPTION to look. Sometimes I want to be able to CAPITALIZE the full word, and other times, I want to just capitalize the first letter of the word.”

Here’s a page from my website with a photo and caption. You’ll see that the CAPITALIZED WORDS do override the formatting code, but every word is also capitalized (like it would be in a title).

So can you please tell me the code to use to make the Caption text look EXACTLY as I type it in the caption box for each photo that I manually add to a page?

Maybe this? or something like this? (I think just replacing the word Captitalize with the proper CSS word might work:

.wp-caption-text {text-transform: case-sensitive !important;}

Since, as far as I know, there is nowhere that a photo caption will appear on my website unless I manually insert content into the caption box, I would like that caption box to override any hard coding that is added into the Ethos theme for the captions (which is set to capitalize every word in a caption).

ALSO, can you tell me the code that I can add where I can manually change the font size of the Captions (they’re pretty tiny, so I’d like to be able to control the caption size, both sitewide (via the Custom-CSS-Customizer box) as well as on individual pages and photos via the Advanced Controls option on each page (which I’m guessing might be the same CSS code, but I only input it on certain pages or photos if I only want to affect that particular photo?)

Hopefully this is clear! 🙂

Thanks for your help and the fabulous support!!

You could try adding this code in your customizer’s custom CSS to make your photo case sensitive:

.wp-caption-text {text-transform: case-sensitive !important;}

To change the photo caption font size.

On a specific page you could add the page class.

for example, the page you shared above,

.page-id-1266 .wp-caption-text {
font-size:12px !important;
}

if you wantn to make it global font size, just remove the page class.
