Overriding Standard Heading Settings | Any HTML document may have three or more style sheets associated with it, including a browser style sheet, a user style sheet, and one or more author style sheets. |
Browsers apply default style sheets to all web documents. Although these browser style sheets vary from browser to browser, they have common characteristics, such as black text and blue links. Most modern browsers allow users to set their own style sheets within their browser. These user style sheets will override any browser default style sheetsfor that user only. As soon as you apply a basic style sheet or an inline style to a page, you have added an author style sheet. Author style sheets will generally override both browser and user style sheets. Most browser style sheets will display an <h1> element in bold text at 200% of the default font size. If you style the <h1> element to 120%, this measurement will be used instead of 200% because your style sheet will override the browser style sheet. |
