There are lots of things you might like to do with CSS, one of which is the font color.

For this reason percentages and ’em’s might be better for accessibility reasons. The only thing to be aware of is that pixel values (like 14px) aren’t adjustable in Internet Explorer for people with poor eyesight who like their text larger. There is no right or wrong answer as to which one is best, so do some experimenting and see what you like best. xx-small / x-small / small / medium / large / x-large / xx-large 0.8ex something to do with the ‘x-height’, whatever that may be. 1.2em something to do with the font-size, but it works. 14pt usually used in print stylesheets (more on these later). Obviously you could use values larger or smaller than 100% to enlarge or reduce the size, but if you’re feeling adventurous there are lots of different ways you can control the size: I’ve used percentages to define my font sizes. The property is separated from the value by a colon, and a semi-colon is used to show that the css property is complete. The property could be the font-size, the color, the border etc, and the value is the value which you wish this property to assume. The paragraph tag has an attribute called style, and this contains some CSS. The technical HTML term is an “attribute”. We’ve just used what I like to call a command inside of a command. To use CSS all we need is the Style attribute: This used to be done using the commands, but they’ve now been depreciated in favor of CSS, so I’m going to give you the CSS now, and explain in more detail later.

Maybe you’d like a little more control over your text size. Once you learn a little CSS in a few of the next primers, you’ll be able to customize them to appear exactly as you want. In-line elements should always be contained in a Block level element. If you guessed Strong and Em fell into this category then you’re really getting the hang of this! These ones don’t create new lines around themselves. It will be the full width of the screen unless you specify otherwise. This means it likes to be a block shape on your page, and it will start new lines around itself. This is because, like the P tag, it’s a block level element.

The heading takes up the entire width available to it. Instead of looking at the headings above and seeing text, I want you to draw an imaginary box, the height of the text and the width of the screen. Heading commands create nice, bold text, as shown above, and are quite easy to use. Note: The numbers 7 and 8 have been added by some browsers, but these are not part of the recognized HTML standard.
