Bootstrap 4 Cards

---

• Using Bootstrap 4 you can create cards.

• Cards are bordered boxes with a bit of padding around the content inside them, which can be used to conveniently display a specific set of information.

** To create a basic Bootstrap 4 card, you need to create a <div> container with the class .card and inside another <div> container with the class of .card-body **

Code example:

<div class="card">
  <div class="card-body">Content</div>
  <!-- content of the card goes here -->
</div>

Header and Footer

---

The structure of the card can be enhanced by the addition of a header and a footer. To add one of these elements, you have to create a <div> container with the .card-header or .card-footer class.

Code example:

<div class="card">
  <div class="card-header">
      <!-- Header content -->
  </div>
  <div class="card-body">
      <!-- Body content -->
  </div>
  <div class="card-footer">
      <!-- Footer content -->
  </div>
</div>

Cards with Images

---

• You may also use specific classes for displaying images in cards.

• There are two classes for this purpose: card-img-top, which places an image on the top of the card, and card-img-bottom, which places the image on the bottom, both of them fitting them to the rounded border of the card neatly.

• These classes have to be used with the <img> tag inside a card to work properly.

• Keep in mind, that if you want an image to span the entire width, you would add the image container outside of the <div> container with the card-body class.

This is how it will look in an html doc

<div class="card">
<!-- content of the card goes here -->
<!-- image on the top of the content -->
  <img src="picture.jpg" alt="Picture" class="card-img-top">
  <div class="card-body">Body content</div>
</div>
<div class="card">
<!-- content of the card goes here -->
  <div class="card-body">Body content</div>
<!-- image on the bottom of the content -->
  <img src="picture.jpg" alt="Picture" class="card-img-bottom"> 
</div>

Cards Overlay

---

• For making an image into the background of the card and displaying the text on top of it you need to use the class card-img-overlay on the content, which you want to display over the image, instead of using the card-body class.

This is how it will look in an html doc

<div class="card">
<!-- content of the card goes here -->
  <img src="picture.jpg" alt="Picture" class="card-img-top">
<!-- this content is displayed over the image, which is now in the background and covers the whole element -->
  <div class="card-img-overlay">Overlay content</div>
</div>

Card is balanced with the image

<div class="card" style="width: 18rem;">
  <img class="card-img-top" src="..." alt="Card image cap">
  <div class="card-body">
    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
  </div>
</div>
<!--You must set the image height on all cards -->
