How do I get the categories OFF my slider images?

If your theme has a built-in custom CSS option, use it; otherwise, get a custom CSS plugin and put:

.home .cat-links {
	display: none;
}

Where do I put it?

Your theme has a custom CSS option available at Dashboard > Appearance > Customize > Design Options > Custom CSS. You can copy and paste the code I provided into that box and then click the “Save & Publish” button.

Yes, thank you so much. But WHERE do I put it? After what?

Here’s what my custom CSS toggle looks like:

/*
Welcome to Custom CSS!

To learn how this works, see https://wp.me/PEmnE-Bt
*/

Do I put if after the last asterisk backslash?

Sorry, “it”, not “if”.

I just put it in and it worked. THANK YOUUUU <3

I just dropped it in and it worked. Thanks a ton, Steve! Nobody else had an answer for me! You’re the best!
