Skewing Elements for Unique Designs

skew() allows us to deviate an element's sides to the coordinate axes on a specific angle. The angle must be specified in degrees (deg). Also, we can determine the skew only for the x-axis or y-axis. The syntax is following:

transform: skew(X_angle, Y_angle);
transform: skewX(angle);
transform: skewY(angle);

skew() accepts 2 values. The X_angle value specifies the skew angle for the x-axis. The Y_angle value specifies the skew angle for the y-axis. If we don't set the second value (Y_angle), the browser understands it as skewX();
skewX(angle) specifies the skew along the x-axis;
skewY(angle) specifies the skew along the y-axis.

Let's run the following example to see what we can get with the help of skewing:

index.html

index.css
