Graphical tutorial on the box-sizing property of CSS3

This time I will bring you a graphic tutorial on the box-sizing attribute of CSS3. Using the box-sizing attribute of CSS3What are the precautions?The following is a practical case, let’s take a look.

Introduction

##The box-sizing properties include content-box (default), border-box,

padding-box.

 

1. Content-box, border and padding are not calculated into width

 

2. Padding-box, padding are calculated into width

3. Border-box, border and padding are calculated into width, which is actually a weird mode~

Note:

ie8+ browser supports content-box and border-box;

ff supports all three values.

When used:

-webkit-box-sizing: 100px; // for ios-safari,

android

-moz-box-sizing:100px; //for ff

box-sizing:100px; //for other

Examples are as follows:

<style type="text/css">
    .content-box{
        box-sizing:content-box;
        -moz-box-sizing:content-box;
        width: 100px;
        height: 100px;
        padding: 20px;
        border: 5px solid #E6A43F;
        background: blue;
    }
    .padding-box{
        box-sizing:padding-box;
        -moz-box-sizing:padding-box;
        width: 100px;
        height: 100px;
        padding: 20px;
        border: 5px solid #186645;
        background: red;                
    }
    .border-box{
        box-sizing:border-box;
        -moz-box-sizing:border-box;
        width: 100px;
        height: 100px;
        padding: 20px;
        border: 5px solid #3DA3EF;
        background: yellow;
    }
</style>
