CSS gives you great control over the way your text is displayed. You can change the text size, color, style, and more. You probably already knew how to make text bold or underlined, but did you know you could resize your font using percentages? Let us begin the lesson with an easy and important font attribute, color!
Although the color of the text seems like it would be part of CSS Font, it actually is a standalone attribute in CSS. This could be for many reasons, including the fact that it will be used a great deal, so why make the coder type out "font-color", when they could just type out "color" instead? Here's an example of changing the color of your font.
h4 { color: red; }
h5 { color: #9000A1; }
h6 { color: rgb(0, 220, 98); }
Font families can be divided into two groups: serif and sans-serif. A sans-serif font does not include the small lines at the end of characters, while a serif font does include these small lines. When choosing which kind you prefer, remember that studies have shown that sans-serif fonts are much easier to read on a computer monitor than serif fonts.
h4 { font-family: sans-serif; }
h5 { font-family: serif; }
h6 { font-family: arial; }
You can manipulate the size of your fonts by using values, percentages, or key terms. Using values are useful if you do not want the user to be able to increase the size of the font because your site will look incorrect if they did so. Percentages are great when you want to change the default font, but do not want to set a static value. Note: Some browsers now have a "Zoom" feature, so it will allow users to make your website bigger or smaller and static values will grow larger/smaller as well.
p { font-size: 120%; }
ol{ font-size: 10px; }
ul{ font-size: x-large; }
CSS Font-Style is where you define if your font will be italic or not. Possible key terms are the following: italic, oblique, and normal.
p { font-style: italic; }
h4{ font-style: oblique; }
If you want to control the weight of your font (its thickness), using font weight is the best way to go about it. We suggest that you only use font-weight in multiples of 100 (e.g. 200, 300, etc) because any less and you probably will not see any difference. The values range from 100 (thin)-900 (thick).
p { font-weight: 100; }
ul{ font-weight: bolder; }
CSS Font Variant allows you to convert your font to all small caps. Note: not every font supports CSS Font Variant, so be sure to test before you publish.
p { font-variant: small-caps; }
