The HTML Font dialogue displays the font attributes for the text for which the dialogue was opened and lets you change them.
Font Combination: This applies the selected font combination to the text. Browsers display text using the first font in the combination that is installed on the user's system. 'Default' specifies the default font. Common fonts for Netscape and Internet Explorer include Helvetica, Arial, Verdana, and so on.
Font Style: This applies the selected style to the text - Regular, Italic, Bold, Bold Italic
Size: This applies either a specific font size (1 through 7) or a font size (±1 through ±7) relative to the basefont size (the default is 3). There is no way to specify a particular point size for fonts in an HTML tag.
Colour: This displays the text in the selected colour. Change the colour by clicking the Fill colour box or changing the value in the adjacent Fill combo box.
