This article mainly introduces the function of the background-clip attribute in CSS. The popular function of the background-clip attribute is to specify the area where the background of the element is located. Friends who are interested in the relevant knowledge of the background-clip attribute in CSS should take a look. Well, I hope it helps everyone.

The popular function of the background-clip attribute is to specify the area where the background of the element is located. There are four values

1, border-box

border -box is the default value, which means that the background of the element retains the background starting from within the border area (including the border).

The simple code is as follows:

<!doctype html>
<html>
    <head>
        <style>
        *{margin:0;padding:0;} 
            .box{width:380px;height:280px;margin:100px auto;background:url("1.jpg") no-repeat -5px;padding:5px;border:5px dotted #000;<br>　　　　　　　background-clip:border-box;}
        </style>
   </head>
   <body>
       <p class="box"></p>
   </body>
</html>

The effect is as follows:

From the picture above We can see that the element background exists in the border and the area by default, but I don’t know why adding a background image cannot cover it all; but the background color does not have this problem.

2. padding-box

padding-box means that the background of the element is retained from within the padding area (including padding).

The simple code is as follows:

<!doctype html>
<html>
    <head>
        <style>
        *{margin:0;padding:0;} 
            .box{width:380px;height:280px;margin:100px auto;background:url("1.jpg") no-repeat -5px;padding:5px;border:5px dotted #000;<br>            background-clip:padding-box;}
        </style>
   </head>
   <body>
       <p class="box"></p>
   </body>
</html>

Copy after login

3. content-box

content-box indicates that the background of the element is retained from within the content area.

The simple code is as follows:

<!doctype html>
<html>
    <head>
        <style>
        *{margin:0;padding:0;} 
            .box{width:380px;height:280px;margin:100px auto;background:url("1.jpg") no-repeat -5px;padding:5px;border:5px dotted #000;<br>            background-clip:content-box;}

</html>

<html>
    <head>
        <style>
        *{margin:0;padding:0;} 
            .box{width:380px;height:280px;margin:100px auto;background:red;padding:5px;border:5px dotted #000;<br>             font-size:100px;font-weight；bold;-webkit-background-clip:text;-webkit-text-fill-color:transparent;}
