W3.CSS Defaults


W3.CSS is Easy to Read

W3.CSS pages are easy to read, even for people with slight reading disabilities.

  • The default font-size is 15px
  • The default font is Verdana, which has a good letter spacing
  • The default line-spacing (1.5) is also very good

HTML Headings <h1> - <h6>

By default, W3.CSS styles HTML headings this way:

Example

<h1>Heading 1 (36px)</h1>

<h2>Heading 2 (30px)</h2>

<h3>Heading 3 (24px)</h3>

<h4>Heading 4 (20px)</h4>

<h5>Heading 5 (18px)</h5>
<h6>Heading 6 (16px)</h6>
