Div {width:980px

Background-color: # ccc

Height:300px;} p {width:100%

/ * width:auto;*/ padding:10px

Background-color:#000

}

If it is the width:100%, of p, it means that the width of p will get 980px, which is already full of div area, and then has its own padding, so it will exceed the div.

When width:auto, it is the overall width (including width,margin,padding,border) equal to the parent width (width, does not include the parent margin,padding,border), so if the padding has taken up the space of the 10px, then the value given by width is 960px.

However, whether it is width:100% or auto, the calculation reference is the parent content area width value, not the total width value.
