* I am new to WordPress. I come from a hand-coded background, building sites from
scratch using HTML, CSS, JS (no PHP). Right now, I am trying to apply a linear
gradient to the body on my site’s About page. I have tried to add the custom
css below in my theme customizer, but the change hasn’t taken effect. Can I (
and should I) edit the appropriate css file in my wordpress folder? Is there
a global “styles.css” file or how would I know which css file to add the code
to?
* In other words, how do I accomplish the below in WordPress?
* ```
//index.html
/*styles.css*/
body{
background: linear-gradient(rgb(0, 0, 0), rgb(109, 2, 82));
}
```

* In WordPress, the theme controls the HTML, CSS, and JS of the front end. Plugins
can also load CSS and JS, and influence the HTML.
WordPress has a function `
body_class()` which themes call for the `` tag. WordPress adds classes
by default, the theme usually adds some more classes, and plugins can also. There
will be a class with a post ID at the very least, that is specific to each page.
The theme may put other unique classes per page. You can use your browser Developer
Tools to examine the classes that are on the body tag, so you can target your
CSS to affect that one page. Your CSS would be put into the Customizer > Additional
CSS, which is output last of all the CSS.
