Build in Font Flexibility to Pages using the ems Unit
Friday, January 4th, 2008Fonts are an integral and essential part of the web page experience for your users. Commonly, designers use pixels as the measurement for determining the size of a font on-screen. Dreamweaver provides a selection of measurement options, but it is ems that is a popular choice due to its flexibility. The ems unit is essentially resizable, for browsers that support this, and their size is relative to a user’s font size preference. For example, if the size of font in the body tag is determined as 100%, all further text is relative to this point. This can be reduced or increased, i.e. 90%, to suit a page design as required. Styling text so that is 0.5ems means that it will always be half the size of the base text. On the opposite scale, 2.0 ems text will always be twice the size of the base text.
