css - How to add animation the featured image?

programmeradmin4浏览0评论

By default I choose featured image from media library. When I hover over each, It shows a black overlay with a plus sign. I have a cool css animation and want to add it to each post featured image. Below is the css animation code that I got from codepen. Anyone know how to do that? I just what to do it. Whether by adding custom css or using hooks or filter or from style.css. the simplest is better.

Any help is most appreciated. Thanks in advance.

  • 1 There are various ways to add custom CSS. Check your theme first and see if it has a "custom CSS" area, often found in the Customizer. If not, there are plugins you can use to add your own CSS. Or, you can build a child theme or a plugin to enqueue your own CSS file. – WebElaine Commented Jan 29, 2020 at 19:39

  • in the animation I want to add, there are is a div that I should add to the html and some css to add to the custom css. even if I find how to add custom css to the featured image. I am still confused where to find the featured image html code to add that div. I am working on a theme named highend. from theme editor I can acess to style.css or any other php files. The only problem I have is where to find featured image html codes. – Ashur Commented Jan 30, 2020 at 8:24

Reset to default 1
  1. Your theme might already have an animation feature, you can just add the class.
  2. You can add a plugin like so..https://wordpress/plugins/animate-it/ and add the class to the featured image property for it to work.
  3. If you use a builder (like Elementor) you can easily create your layouts and add animations to each element.
