How to fix vanilla comments extra iframe space

UPDATE

The frame element has a height of 1000px. I am not sure which file generates the comment form, but the height seems to be in that file. Simply delete height=1000px to remove the space.

Also, if you want to remove the Vanilla credit and link, add .vanilla-credit {display:none !important} to your style sheet.

ORIGINAL

I believe you are referring to the large space between the bottom of your post and the “Leave Comments” title to the comment textarea.

If so, there is a pretty large bottom margin in the .post class in your style sheet. You can remove it by changing it to margin:0
