CSS中的linear属性是什么意思?
background-position 0.1s linear;
我正在查看此代码并且不熟悉线性属性。这如何改变按钮的渐变?
.btn:hover {
color: #333333;
text-decoration: none;
background-color: #e6e6e6;
background-position: 0 -15px;
-webkit-transition: background-position 0.1s linear;
-moz-transition: background-position 0.1s linear;
-ms-transition: background-position 0.1s linear;
-o-transition: background-position 0.1s linear;
transition: background-position 0.1s linear;
}
