How do I completely auto (100%) width display of your content on Android in CSS?

Answer 1

Regardless of the platform, CSS is still CSS. It doesn't matter if you use CSS on an app, a website, or wherever.

As far as automatic 100% width, that's a concept of HTML called "block level elements".

Block level elements are elements that act as whole blocks of content, think of them like a brick in a wall but that extend the entire wall, hence, they are 100% as wide as the container they sit in.

A few examples of block level elements are:

1. Headings: <h1>…<h6>
2. Paragraph: <p>
3. DIVs: <div>, <section>, <aside>
4. Header: <header>
5. Footer: <footer>
6. Lists and list items: <ul>, <ol>, <dl>, <li>

etc.
