    Heights in CSS are a pain to deal with. They almost never work as you expect and they always seem to be larger or smaller than you want them to be. In this video I will show you why things like height: 100% do not work like you expect and what you can do to make them work.

    This pain with heights in CSS is related to how web pages in general are vertical scrolling by default. In any other application UI framework, such as mobile (Native iOS, Android, RN, Flutter, et al), or desktop (like FX, Qt or Swing), the base behaviour takes into account the full viewport as defined by the device (or window dimensions), and scrolling is opt-in on a per element/component/view basis. I ran into this issue whilst building out an Electron application where I wanted to emulate the desktop experience by making the main DIV a viewport height of 100%, and adding in components that had internal scrolling. It was very difficult to define, say, a view that would have scrolling content on a non-scrolling page that would take up the remaining space in its respective column. It was a YUUUGE pain in the arse, and I never did iron out all the CSS bugs. Mind you, I built this using flex box when it was sort of new. I'd imagine if I needed to do something similar in the future, CSS grid would be more helpful in this regard.

    Off topic: Web stores differ in how the behave upon navigation back (like: from a product view back to the gallery view which you have scrolled down a lot). Some do restore original scroll position, some don't, some frameworks provide settings on the router to control that, but what are the browser defaults, what can a dev do to effect this behavior? I'd be curious to hear you talk about it.

    • @WebDevSimplified

      That is just how css was made. I think they did this since there was no way to make something fill the full viewport height when css was first created.

    • @jshstuff

      @@WebDevSimplified from the CSS W3 spec:
      "The background of the root element becomes the background of the canvas and covers the entire canvas, anchored (for 'background-position') at the same point as it would be if it was painted only for the root element itself. The root element does not paint this background again. "
      but I thought the html element is the root element, right..? like the :root selector? So I thought I might ask ChatGPT for an answer:
      Me: "hi ChatGPT, the spec indicates that the root element's background overflows and becomes the background for the whole canvas. If the html element is the root, not the body, why does applying a background to the body set the background color for the whole canvas, even if the body doesn't fill the canvas?"
      ChatGPT: "You are correct that the HTML element is the root element and not the body element. However, in most cases, the body element is the containing block for the entire document and covers the entire canvas. Therefore, when you set a background color or image on the body element, it effectively becomes the background of the canvas. To be more precise, when you set a background on the body element, the browser will render it as the background for the body element and will also propagate it to the viewport (which is the visible portion of the canvas) and any areas outside of the body element. This is because the body element fills the entire viewport by default, so the background applied to it will cover the entire canvas. So while the root element technically overflows and becomes the background for the whole canvas, in practice, the body element is usually used as the containing block and has the same effect.
      **So, TL;DR: it's all about the containing block of the element with the background**
      But ChatGPT said "*in most cases* the body element is the containing block for the whole document". So I asked a follow up:
      Me: "show me a case where setting a background on the body will not cause propagation to the html element"
      ChatGPT: "One case where setting a background on the body element will not cause propagation to the html element is when the html element has a fixed height and the body element's height is set to 100%."
      "In this case, the body element will only take up the height of its content, which may be smaller than the height of the html element. As a result, the background set on the body element will only cover the area within the body element and will not propagate to the html element."
      "Here is an example of CSS code that demonstrates this:"
      ``` css
      html {
      height: 500px;
      background-color: blue;
      }
      body {
      height: 100%;
      background-color: red;
      }
      ```
      "
      (end chatGPT)
      This was a cool little rabbit hole to go down :)

    as you showed in the video it will expand the card and in my use case I don't want that. I want it to fill the remaining height but when the content gets higher than the min-height I want it to have a scrollbar. I've tried to set the scroll-y to scroll but it doesn't work.

      if you don't want the container to go beyond a certain height then you should go with height instead of min-height, or use max-height alongside min-height. when the content goes beyond the limit of the container it will 'overflow' and act based upon the overflow property, which in your case for showing scrollbar it should be auto (default) or scroll

    The behavior of the body-height is very weird (Minute 2:20): It has height of 400px, you can see this because of the blue-border, but the background-color which is #333 fills the entire screen. So the body is 400px height, but on the same time it is also 100% height.
