Without CSS you need to set the style for each paragraph on your page:
<p><font color=”#800090″ face=”Verdana,Geneva,Arial,Helvetica”>The latest update of Oracle Solaris 11 delivers unprecedented scale for cloud infrastructures and Oracle environments.</font></p>
You can use CSS to define in the style sheet that the color property of the <p> tag is #800090, and that the font-family should be Verdana, Geneva,Arial,Helvetica:
Now, every time you add to your document text enclosed in a <p> tag, it will take on this style, and save you from needing to add extra markup to your documents. If you client wants to change the font from Geneva to Times on 100 documents, you can change it only in one place.
