How to right-align text in a text field



Very often you need to right-align text in a text-box, mostly for financial calculations.
One of the solutions proposed was to use table cell padding, i.e. to add empty spaces before a number. Naturally, you need to calculate the length of the number string and make heavy use of javascript. Is there a simpler solution?

The answer is yes. The right solution is to use the Cascading Style Sheets (CSS). Use the following class selector:

.tar {text-align:right}

The selector name is arbitrary, of course, whereas the contents of the braces are not. Then, within the html input tag use the following: class=tar .
That's all it takes.

Highlight text-box background color

OnMouseOver ="this.style.background ='blue'";
OnMouseOut = "this.style.background=''";

Unfortunately, if no stylesheets are used for the input tag, on Windows XP, the above would change the text-box appearance. The following INPUT style will help to eliminate this problem: 

	INPUT{
		BORDER-RIGHT: 1px solid; PADDING-RIGHT: 1px;
		BORDER-TOP:  1px solid;    PADDING-LEFT: 1px;
		PADDING-BOTTOM: 1px;
		BORDER-LEFT: 1px solid;
		PADDING-TOP: 1px;
		BORDER-BOTTOM: 1px solid
   }
