Trouble arises with CSS flexbox functionality when connecting to Bootstrap 4 CDN

I'm currently utilizing CSS flexbox to design the header of my webpage by using display:flex; However, I've noticed that when I include the Bootstrap 4 CDN link in my HTML, the flexbox no longer functions as intended and the different divs within the flexbox are being displayed on separate lines. I would greatly appreciate any assistance with resolving this issue. Thank you.

Answer №1

Your personalized CSS class is currently conflicting with Bootstrap-4 CSS class. To prevent this conflict, you can take the following steps:

  1. Start by adding the Bootstrap-4 CDN followed by your custom CSS. This will override Bootstrap's CSS with your custom CSS.

Example:

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous">
<!-- Bootstrap CDN -->
<link rel="stylesheet" href="your-custom.css" />
<!-- Your custom CSS -->
  1. If the above solution does not resolve your issue, navigate to your HTML and change the Bootstrap class to your custom class.

Example:

<nav class="navbar"></nav>
<!--  -->

The classes mentioned above are reserved by Bootstrap. If these class names conflict with your .navbar class, please adjust the class.

<nav class="my-navbar"></nav>
<!-- OR -->
<nav class="navbar my-navbar"></nav>
  1. If the previous solutions do not work, consider using !important after the CSS property. This will prioritize your custom CSS over Bootstrap's CSS.

Example:

.navbar{
    display: flex !important;
}

Note: It is recommended to avoid using !important with CSS properties. Instead, create new classes to overwrite Bootstrap's CSS.

Answer №2

It seems like your css may be getting overridden by bootstrap's css. Because you are using a CDN, you are unable to modify the bootstrap css.

I recommend trying to add '!important' to your header styles to see if that will take precedence over the BS css.

You can also analyze which styles are being applied by viewing your page in Chrome and pressing F12. Navigate to the 'Elements' tab, select your header on the left, and inspect the Styles on the right. This will display the styles that are currently in effect.
