9 9  The easiest way to include CSS in your WebObject application is put a style block in your <head> tag:

11 -{{code}}
11 +{{code value="xml"}}
12 12  
13 13  <style type="text/css">
14 -{panel}
15 15   table {
16 16   border-style: solid;
17 17   border-color: black;
18 18   border-width: 1px;
19 19   }

23 +=== Static Reference ===
26 26  
27 27  Another easy way to use CSS in your WebObjects application is to include a static reference to it with:

29 -{{panel}}
27 +{{code value="xml"}}
30 30  
31 - <link rel = "stylesheet" type = "text/css" href = "/webserver/relative/path/to/mystyles.css">
29 +<link rel = "stylesheet" type = "text/css" href = "/webserver/relative/path/to/mystyles.css">
32 32  
33 -{{/panel}}
31 +{{/code}}
34 34  
35 35  However, if you're a WO developer, you know static resource references feel dirty. Don't worry, there are alternatives.
