In CKEditor the Font is the typeface that will be applied to the document text. Fonts are pre-defined sets of characters with uniform styling collected under one name. The CKEditor collection of fonts includes most popular serif fonts (Times New Roman, Georgia), sans-serif fonts (Arial, Verdana, Tahoma), and monospaced fonts (Courier New).

To change a font for a text fragment, open the Font menu by clicking the Font button on the toolbar. The font drop-down list contains a number of typefaces that you can use. To make the choice easier, the font names are displayed in a font that they represent, giving you a preview of what the text will look like.

A font can be applied to the whole document, a paragraph, or a text fragment of arbitrary length — even a single letter. Do note, however, that for esthetic and readability reasons it is recommended not to combine too many different fonts in one document.
