There are two common ways to introduce images using Bootstrap: use the element to specify the src attribute; use the img-fluid class to adapt the image to the width of the container.

How to use Bootstrap to introduce images

Bootstrap provides a variety of ways to introduce images. Here are the two most popular ones: Commonly used methods:

Use img element

This is the most direct method, just use <img src="/static/imghwm/default1.png" data-src="image.jpg" class="lazy" alt="How to introduce images into bootstrap" > element, and specify the src attribute to point to the path of the image. For example:

<code><img src="/static/imghwm/default1.png" data-src="image.jpg" class="lazy" alt="图片说明"></code>

Use the img-fluid class

Bootstrap provides the img-fluid class, which can make images automatically Fits to the width of the container. To use this method, add the img-fluid class on the <img class="img-fluid lazy" src="/static/imghwm/default1.png" data-src="image.jpg" alt="How to introduce images into bootstrap" > element. For example:

<code><img class="img-fluid lazy" src="/static/imghwm/default1.png" data-src="image.jpg" alt="图片说明"></code>

Other options

In addition to the above two methods, Bootstrap also provides other options to control the appearance of the image:

• img-thumbnail Class: Creates a thumbnail with borders and rounded corners.

• img-circle Class: Create a circular image.
• figure Elements: Add a title and description to the image.

Tips
