Making a sidebox with fixed height

[gjh42]

Or, since you have created the new sidebox with the name of editable_sidebox4, the view source should have a line which includes an id of editable_sidebox4 (unless Template Monster has deleted the box id output from its code). If you are unsure about the box id, let us see your site live and we can tell you what it is if it is there. You can then use the box id in your stylesheet to control that particular box without upsetting any existing styling.

The line shown will work as schoolboy says to control the content of the box (everything below the box heading). This is probably all you need for your current purpose, but if you want to affect the whole box, use the overall box id.
