HTML-CSS: Offscreen
HTML-CSS : Exercise-39 with Solution
Using HTML, CSS hides an element completely (visually and positionally) in the DOM while still allowing it to be accessible.
- Remove all borders and padding and hide the element's overflow.
- Use clip to define that no part of the element is shown.
- Make the height and width of the element 1px and negate them using margin: -1px.
- Use position: absolute so that the element does not take up space in the DOM.
- Note: This technique provides an accessible and layout-friendly alternative to display: none (not readable by screen readers) and visibility: hidden (takes up physical space in the DOM).

A min-height for table, tr or td:
It's not a nice solution but try it like this:
<table> <tr> <td> <div>Lorem</div> </td> </tr> <tr> <td> <div>Ipsum</div> </td> </tr> </table>
and set the divs to the min-height:
div { min-height: 300px; }
