Bootstrap 4 utility classes for Bootstrap 3 or any other project in LESS and CSS. These are very useful helper classes including common as well as responsive float, spacing and text-align classes which you can easily include in any of your project.
Just download the project and include the CSS file in your project. Nothing fancy here! You can also include the LESS files in your project and add your own custom utility classes on top of it.
Include the stylesheet on your document's <head>
<head>
<link rel="stylesheet" href="bootstrap-4-utilities.min.css">
</head>Next, start adding the classes as and when required.
The utility classes are categorized as Float, Text Align and Spacing and each category is divided into two sections - Common and Responsive.
For responsive utility classes, the breakpoints are considered same as in Bootstrap 3 which are the following:
xs (<768px)(This breakpoint abbreviation is not used in the classes as it applies to all the breakpoints from xs to xl)sm (≥768px)md (≥992px)lg (≥1200px)
Please find the details of the available classes below.
Toggle floats on any element, across any breakpoint, using responsive float utilities.
<div class="float-left">Float left on all viewport sizes</div>
<div class="float-right">Float right on all viewport sizes</div>
<div class="float-none">Don't float on all viewport sizes</div><div class="float-sm-left">Float left on viewports sized SM (small) or wider</div>
<div class="float-md-left">Float left on viewports sized MD (medium) or wider</div>
<div class="float-lg-left">Float left on viewports sized LG (large) or wider</div>
<div class="float-sm-right float-lg-left">Float right on viewports sized SM to MD. Float left on viewports sized LG or wider</div>All available float classes:
.float-left.float-right.float-none.float-sm-left.float-sm-right.float-sm-none.float-md-left.float-md-right.float-md-none.float-lg-left.float-lg-right.float-lg-none
Easily align text to left, right or center, across any breakpoint, with text alignment classes.
<p class="text-left">Left aligned text on all viewport sizes.</p>
<p class="text-center">Center aligned text on all viewport sizes.</p>
<p class="text-right">Right aligned text on all viewport sizes.</p><p class="text-sm-left">Left aligned text on viewports sized SM (small) or wider.</p>
<p class="text-md-left">Left aligned text on viewports sized MD (medium) or wider.</p>
<p class="text-lg-left">Left aligned text on viewports sized LG (large) or wider.</p>
<p class="text-sm-right text-lg-left">Right aligned text on viewports sized SM to MD. Left aligned text on viewports sized LG or wider</p>All available text alignment classes:
.text-left.text-right.text-center.text-sm-left.text-sm-right.text-sm-center.text-md-left.text-md-right.text-md-center.text-lg-left.text-lg-right.text-lg-center
Assign responsive-friendly margin or padding values to an element or a subset of its sides with shorthand classes. Includes support for individual properties, all properties, and vertical and horizontal properties.
The classes are named using the format {property}{sides}-{size} for xs, i.e., across all breakpoints and {property}{sides}-{breakpoint}-{size} for sm(≥768px), md(≥992px), and lg(≥1200px).
Where property is one of:
m- for classes that setmarginp- for classes that setpadding
Where sides is one of:
t- for classes that setmargin-toporpadding-topb- for classes that setmargin-bottomorpadding-bottoml- for classes that setmargin-leftorpadding-leftr- for classes that setmargin-rightorpadding-rightx- for classes that set both*-leftand*-righty- for classes that set both*-topand*-bottom- blank - for classes that set a
marginorpaddingon all 4 sides of the element
Where size is one of:
0- for classes that eliminate themarginorpaddingby setting it to 01- (by default) for classes that set themarginorpaddingto .25rem2- (by default) for classes that set themarginorpaddingto .5rem3- (by default) for classes that set themarginorpaddingto 1rem4- (by default) for classes that set themarginorpaddingto 1.5rem5- (by default) for classes that set themarginorpaddingto 3remauto- for classes that set themarginto auto
<div class="mt-0">Margin top 0 on all viewport sizes</div>
<div class="ml-1">Margin left .25rem on all viewport sizes</div>
<div class="px-2">Padding left and right .5rem on all viewport sizes</div>
<div class="p-3">Padding 1rem on all sides across all viewport sizes</div><div class="mt-sm-0">Margin top 0 on viewports sized SM (small) or wider</div>
