Simple Style Sheets

Cascading Style Sheets

The purpose of a style sheet is so you can define a single document that can serve as a basis for creating all your pages.
If you want to change a color or font, you just change one or two documents, not all of them. (A website might have hundreds of pages).
CSS Styles can be stored directly in an html file, or in a separate style sheet file (with a .CSS extension)

To be reuseable, you'll want to define a separate file.

Within the style sheet you'll want to define the default settings for common tages (e.g. body, paragraph, heading, links), and some common divisions.

to create a new setting for a tag, type in the tag name with its style settings inside of braces { }.
to create named divisions, just use div.name followed by braces containing the settings for that division

in the example below, div.top creates a divsion class callled top, that can be later used in an html file by using the class attribute,
e.g. <div class = "top" >

Use the <link> tag to link a .css file to your .html file. This shoiuld go into the header area.

use /* and */ to comment the code (similar to java)

<p>Four score and seven years ago our fathers brought forth on this continent a new nation,
conceived in liberty, and dedicated to the proposition that all men are created equal.</p>
<p>
Now we are engaged in a great civil war, testing whether that nation, or any nation,
so conceived and so dedicated, can long endure. We are met on a great battle-field of that war.
We have come to dedicate a portion of that field, as a final resting place for those who here gave
their lives that that nation might live. It is altogether fitting and proper that we should do this.
</p>
<p>
But, in a larger sense, we can not dedicate, we can not consecrate, we can not hallow this ground.
The brave men, living and dead, who struggled here, have consecrated it,
far above our poor power to add or detract. The world will little note, nor long remember what we say here,
but it can never forget what they did here. It is for us the living, rather,
to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. </p>
<p>
It is rather for us to be here dedicated to the great task remaining before us that from these honored
dead we take increased devotion to that cause for which they gave the last full measure of devotion
that we here highly resolve that these dead shall not have died in vain that this nation, under God,
shall have a new birth of freedom and that government of the people, by the people,
for the people, shall not perish from the earth.
