    For some reason I can’t figure out, the value returned by element.scrollHeight is about 50-60px more than the actual content height. It should represent the height of the inner p element here but is consistently higher. What am I missing?

    codepen.io/anon/pen/NwNoaq

    I’ve used this kind of thing a million times before, successful as far as I’m aware of…

    The scrollHeight is logged to the console. Please take a moment to look at the actual height of the inner element through the console and compare it. Not matching up at all.

    If overflow-y: scroll is removed from .panel, the value is suddenly correct.

    Thanks in advance for any insight.

    Just as strange, I get the same result when using jQuery’s .height() on the p element…

    Seems all this stuff got somehow messed up. Yesterday outerWidth() was all over the place too.

    Either that or I’m having a major blind spot momentarily.

    Edit – logging the entire element itself shows the correct amount of pixels for scrollHeight among the list of properties.

    I’ve now also added a click function (for the small custom scrollbar) which presents the correct result.

    ???

    Wow, I’m a total idiot. Only realising that after stripping down the code:

    codepen.io/anon/pen/wPGZRN

    Here the height is actually the presumed incorrect value but I’m changing the width of the element a bit later on myself in order to put the scrollbar out of view (which was the entire intention of the pen initially), with which it has a bit more space and becomes somewhat shorter.

    My brain really has to get into coding again. Like in the early days, spending hours over something rather obvious. :-/

    Lol, much better now.
