- Methods of using Styles:Methods of using Styles: Styling can be added to HTML elements in 3 ways: 1. Inline - using a style attribute in HTML elements 2. Internal - using a <style> element in the HTML <head> section 3. External - using one or more external CSS files The most common way to add styling, is to keep the CSS syntax in separate CSS files.

- CSS Syntax SampleCSS Syntax Sample Configure a Web page to display blue text and yellow background. body { color: blue; background-color: yellow; } This could also be written using hexadecimal color values as shown below. body { color: #0000FF; background-color: #FFFF00; } 5
- Color ValuesColor Values CSS colors are defined using a hexadecimal (hex) notation for the combination of Red, Green, and Blue color values (RGB). The lowest value that can be given to one of the light sources is 0 (hex 00). The highest value is 255 (hex FF). Hex values are written as 3 double digit numbers, starting with a # sign.

- 1. External Style Sheets1. External Style Sheets CSS style rules are contained in a text file separate from the XHTML documents. The External Style Sheet text file: ◦ extension ".css" ◦ contains only style rules ◦ does not contain any XHTML tags 11
- 1.External Style Sheets -1.External Style Sheets - cont.cont. ◦ Multiple web pages can associate with the same external style sheet file. ◦ Each page must include a link to the style sheet with the <link> tag. The <link> tag goes inside the head section: 12 mystyle.css index.htmindex.htm clients.htmclients.htm about.htmabout.htm Etc…
- 2. Internal Style Sheet2. Internal Style Sheet An internal style sheet should be used when a single document has a unique style. You define internal styles in the head section of an HTML page, inside the <style> tag, like this: Example:
- Multiple Style SheetsMultiple Style Sheets If some properties have been set for the same selector in different style sheets, the values will be inherited from the more specific style sheet. For example, assume that an external style sheet has the following properties for the h1 selector: then, assume that an internal style sheet also has the following property for the h1 selector: The left margin is inherited from the external style sheet and the color is replaced by the internal style sheet.
- 3. Inline Styles3. Inline Styles To use inline styles, add the style attribute to the relevant tag. The example shows how to change the color and the left margin of a h1 element: An inline style loses many of the advantages of a style sheet (by mixing content with presentation). Use this method sparingly!
