Reduce white space in Mobile

Site URL: http://www.karektr.com

I'm trying to reduce the white space between certain pages in mobile view.  It seems to differ from page to page as per the attached images. I've checked and there are no extra blocks.

Any assistance would be greatly appreciated.

Hi thank you for responding. I've removed the password from the site. I managed to fix a few pages but the about me and brand experience page is still showing a large space in mobile.

Add to Home > Design > Custom CSS

@media screen and (max-width:640px) {
/* about me */
div#block-yui_3_17_2_1_1594646491940_22948 {
    display: none;
}
/* brand */
div#block-yui_3_17_2_1_1594657361296_43056 {
    display: none;
}
}

That worked perfectly, thank you so much, you're a legend!!
