CSS Helpers

Useful css classes for admin side. To use these helpers, add fw to your style dependencies:

wp_register_style(..., ..., array('fw'));


Alignment classes

Easily realign text to components with text alignment classes.

<p class="fw-text-left">Left aligned text.</p>
<p class="fw-text-center">Center aligned text.</p>
<p class="fw-text-right">Right aligned text.</p>
<p class="fw-text-justify">Justified text.</p>
<p class="fw-text-nowrap">No wrap text.</p>

Transformation classes

Transform text in components with text capitalization classes.

<p class="fw-text-lowercase">Lowercased text.</p>
<p class="fw-text-uppercase">Uppercased text.</p>
<p class="fw-text-capitalize">Capitalized text.</p>

Responsive images

Images can be made responsive-friendly via the addition of the .fw-img-responsive class. This applies max-width: 100%; and height: auto; to the image so that it scales nicely to the parent element.

<img  src="..."  class="fw-img-responsive"  alt="image Responsive" >

Delete icon

Use the generic delete icon for links that delete something.

<a href="#" class="dashicons fw-x"></a>

Quick floats

Float an element to the left or right with a class. !important is included to avoid specificity issues. Classes can also be used as mixins.

<div class="fw-pull-left">...</div>
<div class="fw-pull-right">...</div>

Center content blocks

Set an element to display: block and center via margin. Available as a mixin and class.

<div class="fw-center-block">...</div>


Easily clear floats by adding .fw-clearfix to the parent element. Utilizes the micro clearfix as popularized by Nicolas Gallagher. Can also be used as a mixin.

<div class="fw-clearfix">...</div>

Showing and hiding content

Force an element to be shown or hidden. These classes use !important to avoid specificity conflicts, just like the quick floats. They are only available for block level toggling. They can also be used as mixins. Furthermore, .fw-invisible can be used to toggle only the visibility of an element, meaning its display is not modified and the element can still affect the flow of the document.

<div class="fw-show">...</div>
<div class="fw-hidden">...</div>

Image replacement

Utilize the .fw-text-hide class or mixin to help replace an element’s text content with a background image.

<h1 class="fw-text-hide">Custom heading</h1>

Grid system

Css helpers includes a responsive, fluid grid system that appropriately scales up to 12 columns as the device or viewport size increases. Grid systems are used for creating layouts through a series of rows and columns that house your content. Here’s how the grid system works:

  • Use rows to create horizontal groups of columns.
  • Content should be placed within columns, and only columns may be immediate children of rows.
  • Predefined grid classes like .fw-row and .fw-col-xs-4 are available for quickly making grid layouts.
  • Grid columns are created by specifying the number of twelve available columns you wish to span. For example, three equal columns would use three .fw-col-xs-4.
  • If more than 12 columns are placed within a single row, each group of extra columns will, as one unit, wrap onto a new line.
  • Grid classes apply to devices with screen widths greater than or equal to the breakpoint sizes, and override grid classes targeted at smaller devices. Therefore, applying any .fw-col-md- class to an element will not only affect its styling on medium devices but also on large devices if a .fw-col-lg- class is not present.

This grid system was inspired from bootstrap with some modifications:

  • Added .fw- prefix to classes
  • Changed media queries screen sizes
  • Rows are used without containers (no .container and .container-fluid)
  • Rows have no padding

Media queries

We use the following media queries to create the key breakpoints to a narrower set of devices.

/* Extra small devices (phones) */
@media (max-width: 782px) { ... }

/* Small devices (tablets) */
@media (min-width: 783px) and (max-width: 900px) { ... }

/* Medium devices (desktops) */
@media (min-width: 901px) and (max-width: 1199px) { ... }

/* Large devices (large desktops) */
@media (min-width: 1200px) { ... }


Using a set of .fw-col-* classes, you can create grid systems that look good on any device:

  • .fw-col-xs-* - extra small devices (phones).
  • .fw-col-sm-* - small devices (tablets)
  • .fw-col-md-* - medium devices (desktops)
  • .fw-col-lg-* - large devices (large desktops)


More details about grid system and examples can be found here.

Responsive utilities

For faster mobile-friendly development, use these utility classes for showing and hiding content by device via media query.


Try to use these on a limited basis and avoid creating entirely different versions of the same site. Instead, use them to complement each device’s presentation.

Available classes

Use a single or combination of the available classes for toggling content across viewport breakpoints.


Extra small devices


Small devices


Medium devices


Large devices


.visible-xs-* Visible Hidden Hidden Hidden
.visible-sm-* Hidden Visible Hidden Hidden
.visible-md-* Hidden Hidden Visible Hidden
.visible-lg-* Hidden Hidden Hidden Visible
.hidden-xs Hidden Visible Visible Visible
.hidden-sm Visible Hidden Visible Visible
.hidden-md Visible Visible Hidden Visible
.hidden-lg Visible Visible Visible Hidden

The .visible-*-* classes for each breakpoint come in three variations, one for each CSS display property value listed below.

Group of classes CSS display
.visible-*-block display: block;
.visible-*-inline display: inline;
.visible-*-inline-block display: inline-block;

So, for extra small (xs) screens for example, the available .visible-*-* classes are: .visible-xs-block, .visible-xs-inline, and .visible-xs-inline-block.
