Starting to Code
CSS style sheets are written like this.
Lets break that down. The first part is the selector, it selects what element the style rule (the part in the {}) gets applied to. Here are a few examples
The first example would set the rule to apply to the body element.
The second would apply to any element with attribute class="my_class", you can set "my_class" to any value you like.
The third will apply to the element with attribute id="my_id" on it. This is much like the class but there can only be one element with a particular id in any one document.
