Let our automated scanner check your large sites using Axe Core and W3C Validator.

The “font” element is obsolete. Use CSS instead.

The <font> element, used to define the font face, size and color in previous versions of HTML, is no longer valid in HTML5. Instead, you should rely on CSS styles.

For example, you can define a font size of 12px, bold text with inline styles like this:

<p style="font-size: 12px; font-weight: bold;">some text</p>
