Fieldset tag is not working in my asp.net website?

i have a fieldset in my asp.net website to make a groupbox look alike.. but its not coming. here's what i am doing :

<fieldset id="fl1" runat="server">
     <legend>My Group</legend>
</fieldset>

screen shot of the page where its not working

only My Group is coming the border isn't coming ... i also used panel but same issue...

i am using ajax toolkit and update panel in this page ...

what should i do?

Solution

The fieldset is visible, it is just the border that isn't. Therefore you, presumably, have a style sheet that is removing the border.

Edit the style sheet so either it doesn't remove the border in the first place, or it adds one in explicitly.
