Differences and changes

Compared with its antecedent Bootstrap 3 the fourth edition utilizes the class

.img-fluid

instead of

.img-responsive

as it used to be. Just what this class indicates is the Bootstrap Image Example will fill up the full width of its own container sizing upward or down as required to protect its proportions. So for beginners-- make certain you bring in

.img-fluid

to your

<div class="img"><img></div>

components whenever you are providing all of them into Bootstrap 4 powered web-site pages.

.img-thumbnail

class and simply slightly round the sharp edges with the

.img-rounded

Responsive images

Pics in Bootstrap are actually generated responsive having

.img-fluid

max-width: 100%;

and

height: auto;

are related to the picture to make sure that it sizes with the parent component.

<div class="img"><img src="..." class="img-fluid" alt="Responsive image"></div>

SVG images and IE 9-10

With Internet Explorer 9-10, SVG pics with

.img-fluid

are disproportionately sized. To resolve this, bring in

width: 100% \ 9

where necessary. This solution improperly scales other pic formats, and so Bootstrap does not use it systematically.

Image thumbnails

Beyond our border-radius utilities , you can utilize

.img-thumbnail

to offer an illustration a curved 1px borderline appeal.

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

.m-x. auto

class as follows :

This particular classes have made a few transformations-- from

.pull-left

as well as

.pull-right

in the former Bootstrap 3 version to

.pull- ~ screen size ~ - left

and

.pull- ~ screen size ~ - right

at Bootstrap 4 up to alpha 5 and lastly inside the sixth alpha-- to

.float-left

plus

.float-right

replacing the

.float-xs-left

plus

.float-xs-right

classes having the dropping of the

-xs-

infix leaving the other

.float- ~ screen sizes md and up ~ - lext/ right

as they remain in Bootstrap 4 alpha 5. ( additional reading)

.text- ~ screen size ~ -right

plus
