scaleX() CSS 函数将每个元素点的横坐标修改为一个常数因子，除了该比例因子为1，在这种情况下，函数是身份变换。 缩放不是各向同性的，并且元素的角度不保守。

+ +

+ +

scaleX(sx) 是 scale(sx, 1) 或 scale3d(sx, 1, 1) 的一个速记/缩写。

+ +
+

Note:

+ +

scaleX(-1) 定义一个 轴向对称性(axial symmetry) ，它具有一个垂直轴通过原点 (由 {{cssxref("transform-origin")}} 属性规定)。

+
+ +

Syntax

+ +
scaleX(s)
+
+ +

Values

+ +
+
s
+
Is a {{cssxref("<number>")}} representing the scaling factor to apply on the abscissa of each point of the element.
