In the latest WordPress theme, twentythirteen, I noticed styles that had padding didn’t affect the width of my box. \u00a0Whenever I add padding, the inside just got smaller and the outside stayed the same. \u00a0Was I dreaming all this time thinking the padding affected the overall width? \u00a0What world was I living in where you say this div is 100px wide, but if there’s 10px padding on each side the width should actually be 80px?<\/p>\n
No, I wasn’t dreaming. \u00a0The WordPress twentythirteen theme has a style called<\/p>\n
box-sizing:border-box<\/pre>\n. \u00a0This causes the width to stay the width and the padding to be on the inside and not affect the width. \u00a0This is amazingly<\/strong> supported in IE 8 and up, and, with some prefixes, webkit and firefox. \u00a0 \u00a0I will always be using the below code from now on.<\/p>\n
