How do I remove the blank white space at the very bottom of my website?

Unwanted baseline spacing is caused by structural markup gaps, unclosed background container tags, margin collapse errors, or script modules pushing tracking containers far past the footer boundaries.

“More often than not, it’s an unclosed container tag or a stray tracking script pushing extra space past your footer. I’ll track down the gap and remove it within 24 hours for $99.”
