Exploring an illustration of Bootstrap

As a newcomer to html and css, I am currently working on building a website using the following example template: http://getbootstrap.com/docs/4.1/examples/dashboard/. My issue is that when I zoom in by pressing cmd + '+' or Ctrl + '+', the left sidebar disappears. I would like to prevent this from happening as I want to view the desktop version of the website on mobile screens as well. I suspect this may be related to the 'sticky' property in the dashboard.css file, but I am unsure of how to address it. To better understand the issue, you can access the dashboard.css and related files by inspecting the source code from the link provided above. Any guidance or suggestions would be greatly appreciated. Thank you!

Answer №1

One way to utilize the em unit in conjunction with media queries is as follows:

.responsive-container {
   width : 50px;
   height : 50px;
   margin : 0 auto;
    background-color: blue;
}

@media (max-width: 30em) {
  .responsive-container {
    background-color: red;
  }
}
<div class="responsive-container"></div>

Check it out on JSFiddle!

By setting a value of 30em, which equates to base font size(16px) * 30 = 480px;

If the width exceeds 519px, which is more than 30em (480px), then the media query will not be effective.

However, when the zoom font size is increased by 110% and the width is reduced to 461.278px, making it less than 30em (480px), the media query becomes active.
