You can also define CSS styles for HTML elements with the id selector. The id selector is defined with #. It has a Unique effect in HTML Document, as it is defined uniquely for each HTML Tag/Element.

The CSS style rule defined below will go with the element that has an “id” attribute with a value of “mycolor”:

# mycolor {color:green}

The style rule below will compare the “li” element that has an id with a value of ” link1″:

li#link1
{
text-align:center;
color:red
}

Again Do NOT start an ID name with a number! It will not work in Mozilla/Firefox.

CSS Comments

Comments are used to distribute your code among the working tags and your comments. It may help you when you edit the source code at a later date to recognize the part of code from the content present in your comments. A comment is ignored by browsers. A CSS comments starts with “/*”, and ends with “*/”, like this:

/*This is a comment*/
