HTML and CSS Reference
In-Depth Information
Although you don't specify an exact width for fl uid or elastic layouts, you might want to
provide limits on how narrow or wide an element can extend. If an element is very wide,
its lines of text might become too long to be easily readable; likewise, if it is too narrow,
its text also can be diffi cult to read. Rather than allowing these problems to occur, you can
specify a minimum or maximum height or width for an element using the style properties
min-width: value ;
min-height: value ;
max-width: value ;
max-height: value ;
where value is once again a length expressed in one of the CSS units of measure. For
example, the style rule
body {
width: 95%;
min-width: 1000px;
max-width: 1400px;
sets the width of the page body to 95% of the width of the browser window, and also
limits the width to a range of 1000 to 1400 pixels. No matter the screen resolution, the
page body width will never go below 1000 pixels or above 1400 pixels. After discussing
the page layout issue with Dan, you both agree to develop the Cycle Pathology home
page as a fl uid layout starting with this particular style rule. You'll add it now to the
cp_styles.css style sheet fi le.
To set the page width:
1. Return to the cp_styles.css style sheet in your text editor.
2. Within the style rule for the body element, insert the following properties, as
shown in Figure 4-17:

another in the document.
