This time I will bring you CSS to draw a red heart. What are the precautions for drawing a red heart with CSS? The following is a practical case, let’s take a look.

Step one:

First draw a square. As shown in the picture:

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>css画桃心</title>
    <style media="screen">
        .heart-body {
            width: 500px;
            margin: 100px auto;
            position: relative;
        }
        .heart-shape {
            position: relative;
            width: 100px;
            height: 100px;
            background-color: #f70e0e;
        }
    </style>
</head>
<body>
    <p class="heart-body">
        <p class="heart-shape"></p>
    </p>
</body>
</html>

The second step:

will use the pseudo elements before and: after, Draw a square on the left and top of the square, and then use the border-radius: 50%; attribute to modify the two squares, and then you will get two circles, as shown in the picture:

.heart-shape:before,
        .heart-shape:after {
            position: absolute;
            content: '';
            width: 100px;
            height: 100px;
            background-color: #ffc0cb;
        }
        .heart-shape:before {
            left: -45px;
        }
        .heart-shape:after {
            top: -45px;
        }

Use border-radius: 50%; Attribute:

.heart-shape:before,
        .heart-shape:after {
            position: absolute;
            content: '';
            width: 100px;
            height: 100px;
            -webkit-border-radius: 50%;
            /**兼容苹果；谷歌，等一些浏览器认*/
            -moz-border-radius: 50%;
            /**兼容火狐浏览器*/
            -o-border-radius: 50%;
            /**兼容opera浏览器*/
            border-radius: 50%;
            background-color: #ffc0cb;
        }

Step 3:

The class name is: heart-shape p. Use the transform: rotate(45deg); attribute to rotate them 45 degrees, as shown in the figure:

.heart-shape {
            position: relative;
            width: 100px;
            height: 100px;
            background-color: #f70e0e;
            -webkit-transform: rotate(45deg);
            /* Safari 和 Chrome */
            -moz-transform: rotate(45deg);
            /* Firefox */
            -ms-transform: rotate(45deg);
            /* IE 9 */
            -o-transform: rotate(45deg);
            /* Opera */
            transform: rotate(45deg);
        }

Xiaoying did not give the background color of the circle and the background color of the square a unified color, so that everyone can see the obvious effect better. Next, Xiaoying set the background color to a unified color, and the final love is It came out, as shown in the picture:

.heart-shape:before,
        .heart-shape:after {
            position: absolute;
            content: '';
            width: 100px;
            height: 100px;
            -webkit-border-radius: 50%;
            /**兼容苹果；谷歌，等一些浏览器认*/
            -moz-border-radius: 50%;
            /**兼容火狐浏览器*/
            -o-border-radius: 50%;
            /**兼容opera浏览器*/
            border-radius: 50%;
            background-color: #f70e0e;
        }
