Because the width of #player-cover-artist and #player-cover-album are both 100%, and if we put #player-cover-share on top of them, once the artist or album get long strings, it will just covered by the share button, which should be a noticeable bug. We could probably change a little bit about the elements arrangement, like to use a parent to contain #player-cover-artist and #player-cover-album, then set the width to maybe 75%, and the rest space is all for "player-cover-share", then the maximum length of artist/album can be controlled and will not be covered. An alternative way is just give both width: 75% to #player-cover-artist and #player-cover-album, and use position: absolute to place the share button to the rest 25%.
