CSS stroke-width用法及代码示例

stroke-width属性用于以SVG形状设置边框的宽度。此属性只能应用于具有形状或文本内容元素的元素。

用法:

stroke-width:<length> | <percentage>

属性值：

length:用于以测量单位设置笔划宽度。它可以采用整数或小数百分比的值。
值不需要具有“ px”或“ em”之类的单位标识符。不带单位的值将基于SVG视图框的坐标系。

范例1：本示例设置无单位的笔划宽度。

<!DOCTYPE html> 
<html> 
      
<head> 
    <title>CSS | stroke-width</title> 
      
    <style> 
        .stroke1 { 
            stroke-width:10; 
            stroke:green; 
        } 
        .stroke2 { 
            stroke-width:30; 
            stroke:red; 
        } 
        .stroke3 { 
            stroke-width:50; 
            stroke:orange; 
        } 
    </style> 
</head> 
  
<body> 
    <h1 style="color:green"> 
        GeeksforGeeks 
    </h1> 
      
    <b>CSS | stroke-width</b> 
      
    <div class="container"> 
        <svg height="300px" width="400px"
            xmlns="http://www.w3.org/2000/svg"> 
            <line class="stroke1" x1="0" x2="250"
                y1="20" y2="20" /> 
            <line class="stroke2" x1="0" x2="250"
                y1="90" y2="90" /> 
            <line class="stroke3" x1="0" x2="250"
            y1="200" y2="200" /> 
        </svg> 
    </div> 
</body> 
  
</html>

输出：
width-no-units

范例2：本示例以像素为单位设置笔划宽度。

<!DOCTYPE html> 
<html> 
      
<head> 
    <title>CSS | stroke-width</title> 
      
    <style> 
        .stroke1 { 
            stroke-width:5px; 
            stroke:green; 
        } 
        .stroke2 { 
            stroke-width:10px; 
            stroke:red; 
        } 
        .stroke3 { 
            stroke-width:20px; 
            stroke:orange; 
        } 
    </style> 
</head> 
  
<body> 
    <h1 style="color:green"> 
        GeeksforGeeks 
    </h1> 
      
    <b>CSS | stroke-width</b> 
      
    <div class="container"> 
        <svg height="300px" width="400px"
            xmlns="http://www.w3.org/2000/svg"> 
            <circle class="stroke1" cx="60"
                cy="50" r="25"/> 
            <circle class="stroke2" cx="60"
                cy="150" r="25"/> 
            <circle class="stroke3" cx="60"
                cy="250" r="25"/> 
        </svg> 
    </div> 
</body> 
  
</html>

输出：
width-pixels

percentage:用于以百分比设置笔划宽度。

例：

<!DOCTYPE html> 
<html> 
      
<head> 
    <title>CSS | stroke-width</title> 
      
    <style> 
        .stroke1 { 
            stroke-width:1%; 
            stroke:green; 
        } 
        .stroke2 { 
            stroke-width:2%; 
            stroke:red; 
        } 
        .stroke3 { 
            stroke-width:3%; 
            stroke:orange; 
        } 
    </style> 
</head> 
  
<body> 
    <h1 style="color:green"> 
        GeeksforGeeks 
    </h1> 
      
    <b>CSS | stroke-width</b> 
      
    <div class="container"> 
        <svg height="300px" width="400px"
            xmlns="http://www.w3.org/2000/svg"> 
            <ellipse class="stroke1" cx="100"
                cy="50" rx="35" ry="25" /> 
            <ellipse class="stroke2" cx="100"
                cy="150" rx="35" ry="25" /> 
            <ellipse class="stroke3" cx="100"
                cy="250" rx="35" ry="25" /> 
        </svg> 
    </div> 
</body> 
  
</html>
