How to open a box during a mouseover on an image

[yiskas]

I have an icon image of "?" that gets information about the field it belongs. I want the image to open a box like a balloon pop-up while the cursor is hovering over it(hovering over the image).

I wrote this:

<div class="formInfo">
  <a href="ajax.htm?width=375">
    <img src="http://bytes.com/images/question_icon.jpg" width="19" height="18">
  </a>
</div>

In the cshtml file.
And I have an Ajax file that defines what is in the box.
But - it dosn't work.
Do i need something else?

You have nothing defined for onmouseover. And that's a javascript event. You could also use the anchor's hover pseudo-element to do it in CSS.

I managed already. I used the hover event in CSS like you suggested. Thank you anyway.

You're missing a closing tag for the image in the code you posted.

Also, I don't see any section for the "info" that you want to display.

You don't need closing tags for images
