overflow-y: scroll not working in firefox; any idea to fix same? [You can look at template section on right hand side]

回答1:

This is a bug. The overflow property is not implemented on fieldsets in firefox. Do you have to use a fieldset? If not I would suggest changing it to a div:

Change:

<fieldset style="border-radius: 5px; padding: 5px;height: 450px; border: solid 1px red; overflow: auto;">

to:

<div style="border-radius: 5px; padding: 5px;height: 450px; border: solid 1px red; overflow: auto;">

回答2:

You should mention the overflow for the section not the fieldset.

<section class="loginform" style="overflow-y: auto;">

And add height: auto for fieldset, so that the content doesn't flow outside.

<fieldset style="border-radius: 5px; padding: 5px;height: 450px; border: solid 1px red; height: auto">

回答3:

Set overflow:auto on the section: .loginform (the parent element of the fieldset)

UPDATED FIDDLE

.loginform
{
    height:450px;
    overflow: auto;
}
