Hi there,
To make the toggle go behind the slideout menu, add this:
#generate-slideout-menu {
z-index: 100002;
}
For the close button to go down, add this:
.offside-js--is-left.slide-opened .slideout-overlay button.slideout-exit {
font-size: 1.4em;
margin-top: 20px;
}
Increase the margin-top value for it to go down further.
As for thickness of the close button, font-weight won’t work because it’s using SVG rather than a font file.
If you want to change its thickness, you’ll have to get a new SVG file with a thicker X
close icon and use it in place of the default SVG icon for the close button.
You can do that using Tom’s code here:
