box-sizing
Over the generations, people realized that math is not fun, so a new CSS property called box-sizing
was created. When you set box-sizing: border-box;
on an element, the padding and border of that element no longer increase its width. Here is the same example as the previous page, but with box-sizing: border-box;
on both elements:
.simple {
width: 500px;
margin: 20px auto;
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}
.fancy {
width: 500px;
margin: 20px auto;
padding: 50px;
border: solid blue 10px;
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}
