If there is someone who can help me answer this question I would greatly appreciate it.I am aware that with class selector you can define different styles for the same type of HTML element.example:p.right {text-align: right}p.center {text-align: center}My question is: Are there standard style attributes that need to be used after the period "." or can I just make up any word.example:span.big {font-family:"Monotype Corsiva";font-size:36pt;color:#FFFFFF}This example seems to have worked for me when I tested it in the browser but I am concerned as to if I am writing the code correctly.Also XHTML should be written in lowercase. Does this rule also apply to hex values such as the example above: #FFFFFFThanksEddie
