About

I’m a huge fan of Underscores, Bootstrap, and Sass. Why not combine these into a solid WordPress Theme Framework? That’s what UnderStrap is (or will be…)

At the moment, UnderStrap is in a very early stage. But if you wan’t, feel free to use it for your own WordPress theme!

Basic Features

• Combines Underscore’s PHP/JS files and Bootstrap’s HTML/CSS/JS.
• Comes with Bootstrap (v3.3.6) Sass source files and additional .scss files. Nicely sorted and ready to add your own variables and customize the Bootstrap variables.
• Uses a single and minified CSS file for all the basic stuff.
• Font Awesome integration (v4.5.0)
• Comes with extra slider script by Owl Carousel (v2.0.0-beta.2.4)
• Simple RTL file.
• Jetpack ready.
• WooCommerce support.
• Child Theme ready.
• Translation ready.

Starter Theme + HTML Framework = WordPress Theme Framework

The _s theme is a good starting point to develop a WordPress theme. But it is “just” a raw starter theme. That means it outputs all the WordPress stuff correctly but without any layout or design. Why not add a well known and supported layout framework to have a solid, clean and responsive foundation? That’s where Bootstrap comes in.

Confused by All the CSS and Sass Files?

Some basics about the Sass and CSS files that come with UnderStrap:

• The theme itself uses the /style.cssfile just to identify the theme inside of WordPress. The file is not loaded by the theme and does not include any styles.

• The /css/theme.css file provides all styles. It is composed of five different SCSS sets and one variable file at /sass/theme.scss:

              - 1 "theme/theme_variables";  // <--------- Add your variables into this file. Also add variables to overwrite Bootstrap or UnderStrap variables here
              - 2 "../src/bootstrap-sass/assets/stylesheets/bootstrap";  // <--------- All the Bootstrap stuff - Don´t edit this!
              - 3 "understrap/understrap"; // <--------- Some basic WordPress stylings and needed styles to combine Boostrap and Underscores
              - 4 "../src/fontawesome/scss/font-awesome"; // <--------- Font Awesome Icon styles
  
              // Any additional imported files //
              - 5 "theme/theme";  // <--------- Add your styles into this file
  

• Don’t edit the files no. 2-4 files/filesets or you won’t be able to update it without overwriting your own work!

• Your design goes into: /sass/theme. Add your styles to the /sass/theme/_theme.scss file and your variables to the /sass/theme/_theme_variables.scss. Or add other .scss files into it and @import it into /sass/theme/_theme.scss.

Installation

• Download the understrap folder
• Upload it into your WordPress installation subfolder here: /wp-content/themes/
• Login to your WordPress backend
• Go to Appearance → Themes
• Activate the UnderStrap theme

Developing With NPM, Bower, Gulp and SASS and [Browser Sync][1]

Installing Dependencies

• Make sure you have installed Node.js, Bower, and Browser-Sync on your computer globally
• Then open your terminal and browse to the location of your UnderStrap copy
• Run: $ npm install then: $ bower install and finally: $ gulp copy-assets

Running

To work and compile your Sass files on the fly start:

• $ gulp watch

Or, to run with Browser-Sync:

• First change the browser-sync options to reflect your environment in the file /gulpfile.js in the beginning of the file:

var browserSyncOptions = {
    proxy: "localhost/theme_test/", // <----- CHANGE HERE
    notify: false
};

• then run: $ gulp watch-bs

How to Use the Build-In Widget Slider

The front-page slider is widget driven. Simply add more than one widget to widget position “Hero”.

• Click on Appearance → Widgets.
• Add two, or more, widgets of any kind to widget area “Hero”.
• That‘s it.
