Trying to style with html and css.

Well, I’m working on a website in pretty basic html + css styling. Nothing fancy. But I wanted to have an events page made with wordpress, that way the people I work with (who don’t have any coding knowledge) can update that page regularly without having to ask me.

I’ve asked around about how to style the wordpress page, to make it look like the rest of my site, but I can’t figure it out.

I noticed that when I go to the wordpress page (which I haven’t done anything with, it’s just the page after installing it) and I look at the source code, it gives me this whole page done with html and css styling, but when I look in the folder with all the wordpress files, there aren’t any html pages, it’s just php.

I was told if I wanted to change the styling, to change the index.php page, but all that has is this:

<?php
/**
* Front to the WordPress application. This file doesn’t do anything, but loads
* wp-blog-header.php which does and tells WordPress to load the theme.
*
* @package WordPress
*/

/**
* Tells WordPress to load the WordPress theme and output it.
*
* @var bool
*/
define(‘WP_USE_THEMES’, true);

/** Loads the WordPress Environment and Template */
require(‘./wp-blog-header.php’);
?>

I want to find the one that shows up in the browser with all the html code.

Any help?

Thanks.
