I have this button with border-radius:50% so it is circular and goes well with the design. Problem is on desktop browsers it shows a rectangular thin line border while in touch screen, it shows a full rectangular background behind the circular element upon tap/touch.
The rectangular shape in touch screens appear in areas not covered by the circle. While in desktops, the thin lines exists all the way.
Any tip to remove them and button remains the same in behavior on click/tap?
