If you make the two characters for one color 00 then there will be none of that color in the final color. The lower the number the less of that color. You may notice that if you put the same amounts of each color you will get some shade of grey. Now you should experiment a little and see what colors you can get. Color NOT Colour.
Links are a very important part of any webpage.
With out them we wouldn't be able to get anywhere. You can link to other pages to be displayed in the browser or you can link to any file. If the type of file you link to cannot be opened in the browser the browser will ask you to download it. You can also link to specific places on the same page. To do this is simple.
