Hyperlink word shifts position on mouse

i have a external css files.
i which i hve some code for mouse over

but in a page i have a hyperlink

<a href=“form.htm” >click</a>
when i put my mosue over click , the word "click " jumps from its position
only for this hyperlink how do i make the word in <a> stable

Following the link to your site posted in another thread, the reason for the shifting seems to be this CSS rule:

#content a:hover {
    float: left;
    padding-top: 10px;
    text-align: left;
    width: 700px;
}

It’s very unlikely that any of these styles would be applicable to an anchor, and they seem more suited to a container or layout element. The stylesheet has no rules for Content so perhaps that is the selector they were intended for. Try either removing it altogether or with the a:hover removed.
