The method window.getComputedStyle retrieves the CSS max-height property containing an unresolved calc() function

Has anyone encountered a challenge with a function related to Angular in their project? Here is a snippet of the code causing issues:

console.log(window.getComputedStyle(this.frontLayer.nativeElement).maxHeight);

And within the component template:

 <div #frontLayer        
      [style.maxHeight]="maxHeight"
      [style.height]="curHeight"
      [style.minHeight]="minHeight">

The maxHeight property is initialized in the ngOnInit lifecycle hook.

However, the result obtained appears unresolved and reads as follows:

calc(100% - 56px)

Does anyone have any suggestions on how to address this issue?

Thank you for your assistance.

Answer №1

Most browsers do not compute the max-height property, except for edge/internet explorer. It is recommended to calculate the height instead. However, if you need to check the max height, here is a workaround that I came up with:

When the position of the child is relative, setting the height to 100% will refer to the parent's height. By subtracting 56 from the parent container's height, we can determine the final value.

In this case, it is best to use the height property as opposed to max-height.
