Mobile frontpage - hiding header logo and minor issue on footer

Site URL: https://www.helmatoimisto.fi/

Hi! I'm trying to hide the header logo on mobile frontpage only (I have managed to hide it on desktop view succesfully). Does anyone have working code for this?

Also, on mobile view the footer has a weird white space in the bottom, any advice how to fix this?

I now have the following custom CSS regarding the mobile footer:

@media screen and (max-width:767px) {
footer.sections section * {
    padding-top: 0 !important;
    padding-bottom: 0 !important;
    margin-top: 0 !important;
    margin-bottom: 0 !important;
}
}

Add to Design > Custom CSS

/* Mobile */
@media screen and (max-width:767px) {
/* Hide mobile logo */
.header-title {
    visibility: hidden;
}
}

Thank you @tuanphan! Your code hides the mobile logo from every page, I would like to hide it only on front page. Is this possible?

I think I solved it:

/* Mobile */
@media screen and (max-width:767px) {
/* Hide mobile logo */
.homepage .header-title {
    visibility: hidden;
}
}

There is still an issue with the homepage footer. It looks on mobile like this (has a unwanted white space on the bottom, there should be a line of white text visible here):

When in all the other pages it looks like this (as it should):

change visibility: hidden; to display: none !important;
