This is a web browser setting. > Do all browsers use the same baseline size? They mostly used to be close, and still are, but less so than in the past. The reasons for the divergence mostly have to do with the higher resolution of modern displays and the methods of setting them. In most cases, particularly on modern hardware, it starts at close to a nominal 12pt, a size that in scientific tests of web user preferences is their overall favorite. http://archivist.incutio.com/viewlist/css-discuss/68515 simply explains the starting points, but remember that these are intended to be adjusted by browser users who find the initial settings not to their liking. In addition, all modern browsers have some kind of shorthand way to increase either the size of page text and/or all page elements including images. The best ones include a way to force text to some minimum size. The worst, IE6 and prior, has a broken resizer that is incapable of resizing text sized in pt, px and other absolute sizes. If you size using these units, many IE users will find the result unusable and be unable to do anything to improve it. > And do all browsers react to percentages the same? The modern versions are close, though some round by truncation while others round mathematically, which often leads to small differences. Note that em units as applied to font sizes are in theory exactly equivalent to percentages - simply the CSS syntax is different. However due to an IE bug, a font size set in em on either html or body elements can cause compound application of sizing on child elements. To avoid that problem any size you set on html and/or body should not be set in ems on pages expected to be used in IE. -- "Respect everyone." I Peter 2:17 NIV Team OS/2 ** Reg.
