  1. Use of color (Basic)

  2. HTML Attributes (telling tags what to do) • We can change the way tags display things on web pages by putting what’s called an "attribute" into an opening tag • Many of the things that were done with attributes are now done with CSS ("Cascading Style Sheet“) • We shall put CSS code into tags by the use of the styleattribute

  3. HTML Attributes (telling tags what to do) • The style attribute’s job is to hold CSS code, that’s the stuff in the quotation marks • An unlimited amount of CSS commands can be added to the style attribute as long as they • are enclosed between the quotation marks and • each command ends with a semi colon

  4. Example

  5. On your web page, this is what it looks like:

  6. If you want the text in red and centred on the web page,

  7. You should add the following attributes: <html><head> <title>My First Webpage</title> </head><body> <h1 style="text-align:center; color:red;">Learning HTML</h1> </body> </html>

  8. Color Attributes • There are the two primary color attributes: • color:This refers to color of any text in the element. • background-color:The background color of the element. (The hyphen is a formal part of the name. If you leave it out, the browser won’t know what you’re talking about.)

  9. Use of color (basic) • In HTML there are two key ways of specifying a color: • color names: A set of names that represent over 200 colors, such as red, grey, fuchsia, etc. • Hex codes: HTML only understands the standard colors and doesn't understand colors like "sky blue" or "pea green“. So if you want these kinds of colors, you need to specify a hex color value. These are six - digit codes representing the amount of red, green, and blue that make up the color, preceded by a hash sign # (for example, #333333 ).

  10. The table below lists the standard colors

  11. Each standard color also has a hex color value

  12. Changing the colors • If used properly, color can really enhance your site. If used incorrectly, it can make your site very difficult to read. • Top 10 viewed colors

  13. Open mypage.html in Notepad

  14. Change the font color of h1 to DarkBlue

  15. Change the font color of h1 to DarkBlue <h1 style="color:darkblue;">Learning HTML</h1>

  16. Inserting a Background • There must be sufficient contrast between backgrounds and text so that the user can read the content. In general, try to use light backgrounds on dark text. • To insert a background color on your web page, use the following code INSIDE your <body> tag, E.g.: <body style="background-color:LightBlue;">

  17. Change the Background color to LightBlue <body style="background-color:LightBlue;">

  18. Change the Background color <body style="background-color:LightBlue;">
