Smallest font size in Chrome
Since Chrome has a smallest font size setting, you can't use CSS to set font size less than (12px, by default): font-size: 6px !important; /* This has no effect ! Sigh .. */ Instead, you may consider to use transform instead: transform: scale(0.833); /* 10/12 = 0.833 */ And you may also consider to shift the <div> container to fix the position changed by transform: position: relative; left: -15px;
