The responsive float tools could be chosen to put an responsive picture floating right or left and alter this placement according to the proportions of the existing viewport.

This specific classes have taken a number of transformations-- from .pull-left plus .pull-right in the prior Bootstrap 3 edition to

.pull- ~ screen size ~ - left and .pull- ~ screen size ~ - right at Bootstrap 4 up to alpha 5 and lastly at the sixth alpha-- to .float-left as well as .float-right switching out the .float-xs-left plus .float-xs-right classes using the dropping of the -xs- infix leaving the other .float- ~ screen sizes md and up ~ - lext/ right as they were in Bootstrap 4 alpha 5.

Coordinate illustrations having the helper float classes as well as text message placement classes. block -level images may possibly be focused using the .mx-auto margin utility class.

<div class="img"><img src="..." class="rounded float-left" alt="..."></div>
<div class="img"><img src="..." class="rounded float-right" alt="..."></div>

<div class="text-center">

On top of that the text placement utilities might be taken applying the .text- ~ screen size ~-left, .text- ~ screen size ~ -right and .text- ~ screen size ~ - center to the parent component where the actual <div class="img"><img></div> component has been wrapped. A brand new option in recent alpha 6 build of the Bootstrap 4 again is connected with the dropping of the -xs- infix-- and so supposing that you desire to for example center an illustration globally-- for all of the sizes together with the text utilities simply just apply the .text-center class.
