CSS: Cascading Style Sheet

CSS is all about adding style to HTML page tags.

Why CSS?

Deficiencies of HTML:

1. Inability to accommodate multiple devices

2. Requires browsers to be intelligent and large enough

3. Data and display are not separated

4. Not powerful enough.

CSS Benefits:

1. Separate data from display

2. reduce network traffic

3. Make the entire site visually consistent

4. Increased development efficiency

CSS syntax

p{color：red;}

selector {property name: property value;}

The selector must be followed by braces. Attribute names must be separated by colons. Attribute values followed by semicolons

It's best not to have spaces between attribute names and colons.

How CSS and HTML are combined

CSS code is theoretically arbitrary, but usually written in style tags

CSS and HTML can be combined in three ways:

a. Row-level stylesheets: style attributes, ranges apply only to this label

Hello everyone

b. inline style sheets: done with labels. Scope for this page

c. External style sheets: Build style sheet files using. For multiple pages.

Ways to introduce style sheet files:

1): Use labels

eg:

2): Use import, must be written in the label, and must be the first sentence

eg: @import url(a.css) ;

The difference between the two ways of introduction:

Labels cannot be written in external stylesheets, but import statements can be written
