JavaWeb——CSS

1. CSS与HTML结合的三种方式

    <div style="border: 1px solid red">div标签div>

<style>
    div{
        border: 1px solid red;
    }
style>

div{
    border: 1px solid red;
}

<link rel="stylesheet" type="text/css" href="test.css"/>

2. 选择器

div{
    border: 1px solid red;
}



<div id="id1">div标签1div>

<style>
        #id1{
            color: blue;
            border: blue solid 1px;
            font-size:20px;
        }
style>


<div class="class01">div标签1div>
<div class="class01">div标签1div>

.class01{
		  color: blue;
		  border: blue solid 1px;
		  font-size:20px;
}


#id1,.class01{
    color: blue;
    border: blue solid 1px;
    font-size:20px;
