Edwin,
What you can do if you want to indent text is just put the style element inside the <div> tag, if you don't want to create a new class.
Example
.bold {
font-weight: bold;
}
Then in the body put:
<div class="bold" style="text-indent: 10px;">Hello World</div>
This is a way round your problem, but I still think the best way is as follows:
<head>
<style type="text/css">
.bold {
font-weight: bold;
}
.boldindent {
font-weight: bold;
text-indent: 10px;
}
</style>
</head>
<body>
<div class="bold">Hello World</div>
<div class="boldindent"> Hello World</div>
Hope this helps....
:)
