Question

today I have a quick question. Here is my function:

function checkheight() {
var heightofdiv = $('#checkforheight').height();
$("#centeredbackground").css("min-height",heightofdiv);
}

My problem is that I want to get my variable, heightofdiv, and then subtract the answer by 42 pixels. So really, I want heightofdiv to be equal to the height of checkforheight minus 42 pixels. If this is even possible, help would be greatly appreciated. Thanks!

Answer 1

Can you not simply subtract 42 from $('#checkforheight').height()?

var heightofdiv = $('#checkforheight').height() - 42;
