CSS选择器优先级详细介绍
本文为大家分享的是CSS选择器优先级相关资料介绍,供大家参考,具体内容如下
1.类的覆盖顺序和应用的时候引用的顺序没关系,覆盖顺序取决于类定义的顺序
例如:
<code class="language-css">.a{ color:red } .b{ color:green } </code>
由于b晚于a定义,所以b覆盖a,反之则a覆盖b
2.类选择器优先级大于标签选择器
例如:
<code class="language-css">div{ color:red } .div{ color:green } </code>
.div将覆盖div
3.类选择器优先级等于纯属性选择器,谁后定义谁优先级高。
例如:
<code class="language-css">[data-name='div']{ color: red } .a{ color:blue } </code>
.a将覆盖[data-name='div'],反之[data-name='div']覆盖.a
4.类选择器优先级小于标签+属性组合选择器。
例如:
<code class="language-css">div[data-name='div']{ color: red } .a{ color:blue } </code>
5.类选择器优先级小于id选择器。
例如:
<code class="language-css">.a{ color:blue } #div{ color: red } </code>
.a将被#div覆盖
6.标签+属性组合选择器优先级小于id选择器。
例如:
<code class="language-css">[data-name='div']{ color:blue } #div{ color: red } </code>
#div将会覆盖[data-name='div']
7.标签选择器优先级小于id选择器。
例如:
<code class="language-css">div{ color:blue } #div{ color: red } </code>
#div将会覆盖div
8.标签选择器优先级小于纯属性选择器。
例如:
<code class="language-css">div{ color:blue } [data-name='div']{ color: red } </code>
div将会被 [data-name='div']覆盖
综上所述: 标签选择器。

To use Bootstrap to layout a website, you need to use a grid system to divide the page into containers, rows, and columns. First add the container, then add the rows in it, add the columns within the row, and finally add the content in the column.

Different layouts under different screen sizes can be achieved by using responsive classes.

Bootstrap's mesh system is a rule for quickly building responsive layouts, consisting of three main classes: container (container), row (row), and col (column). By default, 12-column grids are provided, and the width of each column can be adjusted through auxiliary classes such as col-md-, thereby achieving layout optimization for different screen sizes. By using offset classes and nested meshes, layout flexibility can be extended. When using a grid system, make sure that each element has the correct nesting structure and consider performance optimization to improve page loading speed. Only by in-depth understanding and practice can we master the Bootstrap grid system proficiently.
