The HTML element in the side menu is not adjusting its size to fit the parent content

Update: What a day! Forgot to save my work... Here is the functioning example. Thank you for any assistance.

I have set up a demo here of the issue I'm facing.

I am utilizing this menu as the foundation for a page I am developing.

The menu is built using Bootstrap 3 and jQuery.

I can't seem to understand why the black sidebar (#sidebar-wrapper) doesn't adjust its size according to the content, always starting at a fixed height. It appears that the initial height matches the visible area of this element.

In essence, I want the menu column to adjust in the following manner:

  1. min-height = screen-height - 50px (leaving space for the header)
  2. or its height should match the height of the main content (#page-content-wrapper) which will contain varying amounts of data.

Through my research, I came across CSS code that expands an element to the full page height (as a minimum):

min-height: 100vh;

However, I haven't been able to incorporate the 50px difference. Am I interpreting it correctly?

Any help would be highly appreciated!

Answer №1

To adjust the minimum height, consider using calc(). This function subtracts 50px from the total height of the page.

min-height: calc(100vh - 50px);

Answer №2

After reviewing your fiddle, it appears that the element is a block element with a fixed height. Additionally, being within a div means it will share its height with other elements inside it. I was able to recreate this based on the sample provided. The #sidebar-wrapper has been given the attribute of position:absolute, causing it to only consider itself and not any other elements.

Here is the replicated example

Answer №3

Give this example a try, I believe it will resolve your issue:

$("#menu-toggle").click(function(e) {
        e.preventDefault();
        $("#wrapper").toggleClass("toggled");
    });
     $("#menu-toggle-2").click(function(e) {
        e.preventDefault();
        $("#wrapper").toggleClass("toggled-2");
        $('#menu ul').hide();
    });

     function initMenu() {
      $('#menu ul').hide();
      $('#menu ul').children('.current').parent().show();
      //$('#menu ul:first').show();
      $('#menu li a').click(
        function() {
          var checkElement = $(this).next();
          if((checkElement.is('ul')) && (checkElement.is(':visible'))) {
            return false;
            }
          if((checkElement.is('ul')) && (!checkElement.is(':visible'))) {
            $('#menu ul:visible').slideUp('normal');
            checkElement.slideDown('normal');
            return false;
            }
          }
        );
      }
    $(document).ready(function() {initMenu();});
