We talked about simple HTML on the first day, and simple CSS on the second day. So today, let’s talk about how to use their combination!

First let’s talk about the reference method and how to use it!
　1. Internal style sheet. (Put it in )

<span style="color: #008080">1</span> <span style="color: #800000"><head></span><span style="color: #008080">2</span> <span style="color: #800000">    <style></span><span style="color: #008080">3</span> <span style="color: #ff0000">        div{
4                 color:red:
5     }</span><span style="color: #008080">6</span> <span style="color: #800000">    </style></span><span style="color: #008080">7</span> <span style="color: #800000"><head><br></span>

Copy after login

[Tip]: The red area is the style, and element selector

2. Inline style sheet (style written in the tag)

<p style="color: red;"></p>

Copy after login

Note: The syntax must be style = ""Attributes and attribute values in double quotes!

　3. External style sheets (introducing external CSS style sheets) are best placed in the head

<span style="color: #008080">1</span> <span style="color: #800000"><head></span><span style="color: #008080">2</span> <span style="color: #800000">        <link rel="stylesheet"  href="xxx.css?1.1.11"><br>　　</head><br></span>

Copy after login

Note: "stylesheet" //Style sheet

href //Address

The xxx in xxx.css is the file name, and it is your customized file name! (Suffix name.css It cannot be changed!)

There is also the CSS selector! The selector is an important part of the CSS style sheet

CSS Selector

　1. Element Selector

div, p, span, hr, etc. Many of the elements that are directly connected to curly braces are element selectors

　2.ID selector (id)

We are here Use the id attribute value in the style sheet to modify the label attribute and style.

Syntax:

       { :; :; }

Copy after login

Then, the effect is like this:

That’s all I’ll write today! And then... I’m going to give up! Because my lecturer said we need to write something taller Don’t write about the basics of what I mentioned above! So I decisively gave up! I will continue to update this when I have time in the future!!!
