[hide]Syntax
As mentioned beforehand, the CSS syntax is
element { property: value; }
After evert property:value statement, there must be a semicolon, a ";". The last statement in an element does not require a semicolon, but it is a good practice to do so anyway.
CSS ignores whatever whitespace, so you can write CSS many ways:
element{property:value;} element { property:value; } etc.
However, it is a good practice to do it the first way; it's more readable, and it's easy to organize and edit.
Elements Usually Edited With CSS In AoPS User Blogs
The body element
In the AoPS User Blogs, the body element is most commonly modified for the:
- Background Image/Color
- Font used generally in the entries and sidebar
Styling the Div Element
When styling a div element, you have to specify which element you are styling. If you are working with a div, you can optionally put div in front (if you are working with a span, then put a span, etc.). To specify an element by id, put # then the id, and to specify an element by class, put a period (a .) then the class. For example
#header{background:green;}
will make the header look something like this
The tag that was modified would be
Header Text
Modifying the Background
The two most common things done to the background of an AoPS User Blog are setting a background image or color. Some of the most commonly used properties for a background image:
- background-color
- background-image
- background-repeat
- background-attachment
- background-position
- background-size
To use them all together, use the syntax,
background: color position size repeat attachment image;
Text formatting
There are some properties used for formatting text. The most commonly used properties are:
- text-align
- text-transform
Text-align is used for aligning text horizontally. Text-transform is usually used for capitalizing the text.
