Sometimes it is just better (faster) to change certain values of a Class inside the Web page rather than do it via CSS file. In these cases how does one do this?
That is for example say we have a CSS class:
font-family: "Lucida Grande", Verdana, sans-serif;
border: 2px dotted blue;
But at times inside a web page we want the value of width to be something else and we want the Font size to be something else, which value is dynamically set by the user. So how does one do this inside the web page?
I mean what do we add to this to tell it that width for example should be 350 and font-size should be 14 Pix?
