Customizing Bootstrap CSS

In my recent code, I included a bootstrap css reference in this manner:

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous">

However, the border that is applied to .card elements by default is not something I like. I attempted to override the bootstrap styling and remove the border by adding style="border: 0" to the card div, but it had no effect.

.card {
  border: 0;
}
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous">

<div class="card card-sm" id="localcard">
  <p> See Thin Border </p>
</div>

Is there a way for me to successfully eliminate this border?

Answer №1

You don't have to create a custom style, just use the built-in class: https://getbootstrap.com/docs/4.1/utilities/borders/

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous">

<div class="card card-sm border-0" id="localcard">
  <p> Look, no border! </p>
</div>

Answer №2

One way to apply the !important tag in CSS is by doing the following:

.card {
  border: 0 !important;
}
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous">

<div class="card card-sm" id="localcard">
  <p> No Border </p>
</div>
