The primary container is brimming with an abundance of content

Question

The primary container is brimming with an abundance of content

Can anyone help me with a CSS issue I'm experiencing in the latest versions of Chrome and Firefox? I can't seem to figure it out on my own.

The problem arises with a container div that has a 50px top margin. Inside this container, there's a sidemenu div set to 100% width. The window height is 650px, but when the content exceeds this height, both the sidemenu and container divs fail to adjust accordingly.

Interestingly, it works fine when you run the snippet, but not when you save the HTML locally and test it. I suspect there may be some StackOverflow CSS solving the issue, but I'm unsure how to identify and resolve it.

edit: Upon further investigation, I've realized that the body height matches the window size, restricting the container div. I still need guidance on how to make sure the body height expands to accommodate the full content.

Answer №1

Make sure to replace the height:100% with min-height:100% in #container and #sidenav selectors.

Here is the updated CSS for you to try:

I hope this solution works for you.

html, body {
  margin: 0;
}

#container {
  margin-top: 50px;
  min-height: 100%; /*change*/
  background-color: lightgreen;
}

#sidenav {
  width: 250px;
  min-height: 100%; /*change*/
  display: grid;
  background-color: green;
  align-content: space-between;
}

#menu {
  grid-column: 1 / 2;
  grid-row: 1 / 2;
  background-color: red;
}

#footer {
  grid-column: 1 / 2;
  grid-row: 2 / 3;
}

<html>
<head>
</head>
<body>
<div id="container">
  <div id="sidenav">
    <div id="menu">
      sidenav<br/><br/><br/><br/><br/>
      sidenav<br/><br/><br/><br/><br/>
      sidenav<br/><br/><br/><br/><br/>
      sidenav<br/><br/><br/><br/><br/>
      sidenav<br/><br/><br/><br/><br/>
      sidenav<br/><br/><br/><br/><br/>
      sidenav<br/><br/><br/><br/><br/>
    </div>
    <div id="footer">
      footer<br/>
      footer<br/>
      footer<br/>
      footer<br/>
      footer<br/>
      footer<br/>
    </div>
  </div>
</div>
</body>
</html>

Update:

Replacing min-height:100% ensures a minimum height even with little content, while allowing the container to expand if there's more content beyond the specified minimum height limit.

This adjustment prevents any overflow issues by setting a minimum height constraint instead of a maximum one.

Answer 5

Answer №3

To simplify achieving this effect, you can use the CSS property height:inherit. This will inherit the 100% height of the body tag.
Make the following code changes:
#container {
    margin-top: 50px;
    height: inherit;  /*edits*/
    background-color: lightgreen;
}

#sidenav {
    width: 250px;
    height: inherit;  /*edits*/
    display: grid;
    background-color: green;
    align-content: space-between;
    position: relative;
}

Alternatively,

Set the body height to 100% first and then inherit from there.
html, body {
  height: 100%;
  margin: 0;
}

#container {
    margin-top: 50px;
    height: inherit;  /*edits*/
    background-color: lightgreen;
}

#sidenav {
    width: 250px;
    height: inherit;  /*edits*/
    display: grid;
    background-color: green;
    align-content: space-between;
    position: relative;
}

Answer 7

Answer №4

Despite the limited number of answers available, I found myself pondering why setting the height to 100% wasn't producing the expected result in your code situation.

To further investigate, I added borders to all sections including HTML and body, which helped clear up my confusion (https://i.stack.imgur.com/EI56z.png).

The image showed that the content was extending beyond the boundaries of both the HTML and body elements, prompting me to delve deeper into why the height at 100% wasn't functioning as intended.

Upon realizing that a height set at 100% would be relative to its parent element (in this case, the body), I examined the heights of both the html and body elements.

It became evident that the html element precisely spanned the full height of the viewport, defined by the browser window rather than the inner content

This insight shed light on why the height at 100% wasn't working as expected. By removing the explicit height declaration or using min-height, the content could expand to fit its entirety without overflowing.

For further context, refer to this related query: height and width on html and body elements.
