# Images

Documentation and examples for opting images into responsive behavior (so they never become larger than their parent elements) and add lightweight styles to them—all via classes.

##### Responsive Images

Images in Bootstrap are made responsive with `.img-fluid`. This applies `max-width: 100%;` and `height: auto;` to the image so that it scales with the parent element.

    <img src="..." class="img-fluid" alt="...">

##### Aligning Images

Align images with the helper float classes or text alignment classes. `block`-level images can be centered using the `.mx-auto` margin utility class. and `height: auto;` to the image so that it scales with the parent element.

    <img src="..." class="rounded float-start" alt="...">
    <img src="..." class="rounded float-end" alt="...">

##### Image Thumbnails

In addition to our border-radius utilities, you can use `.img-thumbnail` to give an image a rounded 1px border appearance.

    <img src="..." class="img-thumbnail" alt="...">

##### Center

Aligning image horizontally center.

    <img src="..." class="rounded mx-auto d-block" alt="...">
