十年河东,十年河西,莫欺少年穷
学无止境,精益求精
描述一:子元素超出父元素的部分隐藏
overflow: hidden; /*将子元素覆盖的地方压下去*/ border: 1rpx solid #0DD0D0 ; /*压下去后 边框就可以展示了*/
描述二:子元素居中于父元素(不管宽高) 父元素如果是个圆,那么下面的CSS效果会将子元素定位到圆心
position: absolute; top:50%; left: 50%; /*相对父元素 向左移动50%*/ transform: translate(-50%,-50%);/*相对自己 向左移动50%,向上移动50%*/
描述三:使内容左右居中
left: 50%; /*相对父元素 向左移动50%*/ transform: translateX(-50%);/*相对自己 向左移动50%,因自己的长度短,所以移动后,会居中*//*左负右正*/
效果(图片左右居中)
