Delete gap between content and footer on front page

Dear officer
For My personal website, there is always a white space between the bottom content and footer, could you give me help on deleting this gap?
Here is my website:www.leon-ren.com

Hello Liang,

I have just checked your website and it looks fine.

Have you already resolved your issue?

Kind Regards, Roman.

Hi,Roman
Thanks for your reply. The fact is it still has a gap when using Edge. And another thing is that I also managed to reduce the gap between header and content. but when I apply the CSS, it seems my Post is too close to the top of the header.

so do you have any idea about the solution? Thanks very much!

Edit main page, then see at bottom where it says “Sydney FP: Social Profile”? That’s the one I think that causes that gap. I changed the colour of mine, but if you want to remove it, play with removing that maybe?

Hello Liang,

Regarding your header/content gap, please try to use something like 30px instead of 0 in this custom CSS rule:

.page-wrap {
    padding: 0 !important;
}

Please feel free to ask any other questions that you might have.

Kind Regards, Roman.
