I want to set a minimum height for tbody in CSS, even if no <tr><td></td></tr>
in tbody, here is my code:
tbody{
height: 500px;
min-height:500px;
}
but it doesn't work. so what should I do to achieve this?
Why you want to do this?
Min-height and height applies to block level elements and table isn't a block level element. Wrap your table inside a div (say div.table-wrap) and apply minimum height to that div.
If you don't want table layout isn't important to you, then just add display:block
to the CSS of tbody.
