There is a block of buttons, I use in the bootstrap project. The color of the buttons decided to adjust for themselves, but the standard blue color still slips when clicked. Used pseudo-class: active, but without results, here is an example:
.commonButton:active { background: #978e83; color: white; z-index:0; }
