CSS Font ======== All CSS Font Properties ----------------------- Property Description ---------------------------------------------------------------------------------------- font Sets all the font properties in one declaration font-family Specifies the font family for text font-size Specifies the font size of text font-style Specifies the font style for text font-variant Specifies whether or not a text should be displayed in a small-caps font font-weight Specifies the weight of a font CSS Font Families ----------------- In CSS, there are two types of font family names: generic family - a group of font families with a similar look (like "Serif" or "Monospace") font family - a specific font family (like "Times New Roman" or "Arial") Generic family Font family Description ------------------------------------------------------------------------------------------------------------ Serif Times New Roman Georgia Serif fonts have small lines at the ends on some characters Sans-serif Arial Verdana "Sans" means without - these fonts do not have the lines at the ends of characters Monospace Courier New Lucida Console All monospace characters have the same width CSS Font Family --------------- The font family of a text is set with the font-family property. The font-family property should hold several font names as a "fallback" system. If the browser does not support the first font, it tries the next font. Start with the font you want, and end with a generic family, to let the browser pick a similar font in the generic family, if no other fonts are available. If the name of a font family is more than one word, it must be in quotation marks, like: "Times New Roman". More than one font family is specified in a comma-separated list p{font-family:"Times New Roman", Times, serif;} Font Style ---------- The font-style property is mostly used to specify italic text. This property has three values: normal - The text is shown normally italic - The text is shown in italics oblique - The text is "leaning" (oblique is very similar to italic, but less supported) p.normal {font-style:normal;} p.italic {font-style:italic;} p.oblique {font-style:oblique;} Font Size --------- The font-size property sets the size of the text. Being able to manage the text size is important in web design. However, you should not use font size adjustments to make paragraphs look like headings, or headings look like paragraphs. Always use the proper HTML tags, like

-

for headings and

for paragraphs. The font-size value can be an absolute, or relative size. Absolute size: Sets the text to a specified size Does not allow a user to change the text size in all browsers (bad for accessibility reasons) Absolute size is useful when the physical size of the output is known Relative size: Sets the size relative to surrounding elements Allows a user to change the text size in browsers If you do not specify a font size, the default size for normal text, like paragraphs, is 16px (16px=1em). Font Size With Pixels h1 {font-size:40px;} h2 {font-size:30px;} p {font-size:14px;} This example work in Internet Explorer 9, Firefox, Chrome, Opera, and Safari. not work in IE prior version 9. Font Size With Em To avoid the resizing problem with older versions of Internet Explorer, many developers use em instead of pixels. The em size unit is recommended by the W3C. 1em is equal to the current font size. The default text size in browsers is 16px. So, the default size of 1em is 16px. h1 {font-size:2.5em;} /* 40px/16=2.5em */ h2 {font-size:1.875em;} /* 30px/16=1.875em */ p {font-size:0.875em;} /* 14px/16=0.875em */ It is possible to adjust the text size in all browsers. A problem with older versions of IE. The text becomes larger than it should when made larger, and smaller than it should when made smaller. Combination of Percent and Em body {font-size:100%;} h1 {font-size:2.5em;} h2 {font-size:1.875em;} p {font-size:0.875em;} Example 1 ---------

Specifying the font-size in px allows Internet Explorer 9, Firefox, Chrome, Opera, and Safari to resize the text.

Note: This example does not work in IE, prior version 9.

Example 2 ---------

This is heading 1

This is heading 2

This is a paragraph.

Specifying the font-size in em allows all major browsers to resize the text. Unfortunately, there is still a problem with older versions of IE. When resizing the text, it becomes larger/smaller than it should.
