我有一个像这样的圆形按钮。
.rock{
height:100px;
width:100px;
border-radius:100px;
border-color:yellow;
border-width:8px;
}
<button class="rock" type='button'>Button</button>
My question is, how can I remove the weird half-colored thing that shows up on the button border and changes when clicked. I just want the button border to be solid yellow.
