It is very simple to define the style properties of the HTML elements in the Tags, eg;
ignoreButtonStyle="font-family:'Tahoma,Arial,Helvetica';font-size:10pt;
border:1px solid #b5bed6; background-color:#dddddd; width: 90px;"
ignoreButtonOnMouseOver="this.style.backgroundColor='#b5bed6';this.style.borderColor='#08246b';"
ignoreButtonOnMouseOut="this.style.backgroundColor='#dddddd';this.style.borderColor='#b5bed6';"
This specifies the style using regular CSS syntax and also specifies onMouseOver/Out Javascript
events to modify the style for an attractive effect.
