HTML Style marginRight用法及代码示例

HTML DOM中的Style marginRight属性用于设置或返回元素的右边距。

    object.style.marginRight
  • 用于设置marginRight属性。
    object.style.marginRight = "length|percentage|auto|initial|
    inherit"

属性值:


  • length:用于以固定长度单位指定边距。默认值为0。

    例:

    <!DOCTYPE html> 
    <html> 
          
    <head> 
        <title> 
            DOM Style marginRight Property 
        </title> 
          
        <style> 
            .container { 
                display:flex; 
                flex-direction:row; 
                padding:10px 1px; 
            } 
      
            .div1, .div2 { 
                padding:5px; 
                border:2px solid; 
            } 
        </style> 
    </head> 
      
    <body> 
        <h1 style="color:green"> 
            GeeksforGeeks 
        </h1> 
          
        <b>DOM Style marginRight Property</b> 
          
        <div class="container"> 
            <div class="div1">Block One</div> 
            <div class="div2">Block Two</div> 
        </div> 
          
        <button onclick="setMargin()"> 
            Change marginRight 
        </button> 
      
        <!-- Script to set marginRight to a fixed value -->
        <script> 
            function setMargin() { 
                elem = document.querySelector('.div1'); 
                elem.style.marginRight = '50px'; 
            } 
        </script> 
    </body> 
      
    </html>                    

    输出:

    • 在单击按钮之前:
      length-before

  • percentage:用于将边距量指定为相对于包含元素宽度的百分比。
