WordPress Default CSS Styles

WordPress gives us full control over the presentation of our websites. We specify which classes and attributes to use in our template files, and then apply CSS using our theme’s custom stylesheet. Behind the scenes, WordPress generates its own classes and IDs, and applies them to specific HTML elements in theme files and database content. Having these default hooks available makes it super-easy to custom-style your theme’s blockquotes, post images, widget items, and much more.
