Detailed explanation of CSS weird box model and standard box model examples

In the HTML document, each label rendered on the page is a box model. This article mainly introduces the detailed explanation of the CSS weird box model and the standard box model. The editor thinks it is quite good, and now I will share it with you, also Give everyone a reference. Let’s follow the editor to take a look, I hope it can help everyone.

The box model is divided into: W3C standard box model and IE standard box model.

Since most of the current mainstream browsers support the W3C standard box model (standard box model), they also retain the analysis of weird box styles. Of course, IE continues to use its own standard box model (weird box model) )

Use two simple examples to introduce these two box models respectively:

Standard box model:

<!--html-->
<p class="box1">
    <p class="box2"></p>
</p>

<!--css-->
.box1{
         width: 200px;
         height: 200px;
         background-color: aqua;
         padding: 30px;
        }
.box2{
         width: 200px;
         height: 200px;
         background-color: red;
        }

The width and height of the outer box here are both: 30 + 200 + 30 = 260px.

         background-color: aqua;
         padding: 30px;
         box-sizing: border-box;
        }
.box2{
         width: 200px;
