transform属性允许你旋转,缩放,倾斜或平移给定元素。这是通过修改CSS视觉格式化模型的坐标空间来实现的。The source for this interactive example is stored in a GitHub repository. If you'd like to contribute to the interactive examples project, please clone https://github.com/mdn/interactive-examples and send us a pull request.
只能转换由盒模型定位的元素。根据经验,如果元素具有display: block,则由盒模型定位元素。
语法
/* Keyword values */ transform: none; /* Function values */ transform: matrix(1.0, 2.0, 3.0, 4.0, 5.0, 6.0); transform: translate(12px, 50%); transform: translateX(2em); transform: translateY(3in); transform: scale(2, 0.5); transform: scaleX(2); transform: scaleY(0.5); transform: rotate(0.5turn); transform: skew(30deg, 20deg); transform: skewX(30deg); transform: skewY(1.07rad); transform: matrix3d(1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, 11.0, 12.0, 13.0, 14.0, 15.0, 16.0); transform: translate3d(12px, 50%, 3em); transform: translateZ(2px); transform: scale3d(2.5, 1.2, 0.3); transform: scaleZ(0.3); transform: rotate3d(1, 2.0, 3.0, 10deg); transform: rotateX(10deg); transform: rotateY(10deg); transform: rotateZ(10deg); transform: perspective(17px); /* Multiple function values */ transform: translateX(10px) rotate(10deg) translateY(5px); /* Global values */ transform: inherit; transform: initial; transform: unset;
transform属性可以指定为关键字值none 或一个或多个<transform-function>值。
值
<transform-function>- 要应用的一个或多个CSS变换函数。 变换函数按从左到右的顺序相乘,这意味着复合变换按从右到左的顺序有效地应用。
none- 不应用任何变换。

border: solid red;
transform: translate(30px, 20px) rotate(20deg);
width: 140px;
