Hi,
For a better user experience, when the user opens the mobile navigation menu then wants to close, just tape any position outside the menu instead of the close icon.
There's no difference exclude the close area size.

You can add the following CSS to Appearance → Customize → Custom CSS to remove the overlay background color:
.penci-menu-hbg-overlay, #close-sidebar-nav {
background-color: transparent;
}
#sidebar-nav {
border-right: 1px solid #dedede;
}
#close-sidebar-nav i {
font-size: 22px;
}
Regards,
PenciDesign.
