HubToolify Education icons with CSS

Background image (Flat: colours kept)

.icon-school-building { background-image: url(svg/flat/school-building.svg); }

Mask (Line: recolour with CSS)

.mask-school-building { background-color: currentColor; mask: url(svg/line/school-building.svg) center / contain no-repeat; }

Masks need the page to be served over http(s); browsers block them on file:// pages.
