Don’t edit your theme’s files.

Use a Child Theme or a Custom CSS Manager plugin to hold your CSS changes.

The code that @triptripper gave was an example. Look at this tutorial https://www.suburban-glory.com/blog?page=114

Okay okay i see. i read the tutorial as well but what exactly and made a child theme i am still on a very beginner’s level tbh so i’m stuck at inserting the example in the style.css (child) how would i insert the code in the style.css to change the whole blog?

Try the Custom CSS Manager plugin.

You enter the CSS into that plugin’s allocated section of the dashboard.

To apply it to all images, use @triptripper’s example;

img:hover {
 /* Declaration Here */
 -webkit-box-shadow:5px 5px 5px #999999;
 -moz-box-shadow: 5px 5px 5px #999999;
 box-shadow:5px 5px 5px #999999;
}

Thank you so much Andrew & Triptripper’s i really appreciate your time and help, Okay I downloaded the CSS plugin worked like a charm for my button’s which i was trying to do anyway. but the pictures on my blog didn’t change. it’s more of a picture blog here is an exact example of the theme i am using i figure maybe a code needs to be placed somewhere else?

Example blog

It works nvm! thank you guys
