JBST is a powerful theme framework that can be used as a standalone website builder or as a framework to create child themes for WordPress. JBST build on the top of Twitter's Bootstrap 3 and is full customizable with LESS. Integrated customizer for easy responsive website building. Right-To-Left (RTL) support. It also has built in support for BuddyPress, BBpress and eCommerce (WooCommerce, JigoShop and WPeCommerce).

Demo of default install: (some quick install notes:


Download the latest version as .zip file. Upload the .zip file to your WordPress theme directory (wp-content/themes) or use Install theme function in your dashboard. Activate the theme in your dashboard ( Appearence > themes ).

Customization and LESS

JBST has a build in customizer and LESS editor. Also read: Integrate LESS in JBST WordPress Theme. LESS implementation build in with WP LESS to CSS which relies on less.php. Add your mixins, variables and function with the editor Appearance > WP LESS to CSS. Check the plugin documentation for advanched options. Optional add LESS code to library/assets/less/custom.less (less/custom.less for child themes) or wpless2css/wpless2css.less (backup when updating the theme!).

Modify the build in Twitter's Boostrap Code: Don't edit wpless2css/bootstrap/variables.less but overwrite the variables in the editor mentioned above.

Note: Edit and add LESS code with the editor, unless you understand what you're doing. Modifications with the editor are saved in the database and not over written or lost when you update your theme. Changing less/custom.less in your child theme will also be save. Cause CSS is valid LESS you could also add CSS code to the LESS editor.

Use the built-in compiler to:

  • set any Bootstrap variable or use Bootstrap's mixins: -@navbar-default-color: blue;
  • create a custom button: .btn-custom { .button-variant(white; red; blue); }
  • set any built-in LESS variable: for example @footer_bg_color: black; sets the background color of the footer to black
  • use built-in mixins: - add a custom font: .include-custom-font(@family: arial,@font-path, @path: @custom-font-dir, @weight: normal, @style: normal);

Other notes and examples Customization and LESS

Security issues

The theme will ask for your FTP credentials when saving your LESS settings or using the customizer. Sending your credentials over a non-secure (http) connection will be a bad idea always. Add your credentials to your wp-config.php to make this file saving easy and secure. Do not forget to chmod your wp-config.php to 0600. More about all this: Using wp_filesystem in Plugins to store customizer settings


The most important changes in Twitter Bootstrap 3 will be the more mobile-first approaching and the grid. From now Twitter’s Bootstrap defines three grids: Extra small (xs) grid for Phones (<768px), Small/Medium grid for Tablets (&gt=;768px), the Medium grid for Laptops (>=992px) and the Large grid for Desktops. The row class prefixes for these grid are “.col-xs”, “.col-sm-”,“.col-md-“ and “.col-lg-”. The Large grid will stacks below 1200px pixels screen width. So does the Medium grid below 992px pixels and the small below 768px. The extra small grid never stacks. (updated for Twitter's Bootstrap3 RC1). Also read: Twitter Bootstrap 3 breakpoints and grid

JBST use the Small grid by default. You can change this in the customizer. (Tiny, Small or Large). The large grid will stack below the 992px and be horizontal for desktop (and large tablets) while the Tiny grid never stacks.

More about the grid and examples on:

NOTE: Twitter's Bootstrap 3 RC2 intoduced a new grid class (col-xs-*). The class is used for mobile phones and col-xs-* will never stack). The new grid classes are add to the settings now.

Without Responsive features

For a non responsive website set the default grid in the customizer to "Extra Small" and set the Max container width.

To remove all responsive features consider to replace the Bootstrap CSS (replace libary/assets/css/bootstrap.min.css) with the one from Also read: Compile Twitter’s Bootstrap 3 without responsive features.

Accessibility / a11y

JBST is a11y ready by default. When building your site by changing the settings or creating a child theme a11y checks can be broken. Color settings should check for contrast. Also other installed plugins or settings can influence the accessibility of your site. JBST helps you to meet the a11y standard but you also have to check your site after changing it. Condsider to install WP Accessibility and check your color settings on GrayBit. Also see Bootstrap a11y theme.
