Installation

There are several ways to install Understrap. We'll look at three of them: (1) classic install by uploading Understrap to a WordPress install, (2) using npm, and (3) using the theme directory in WordPress.

Classic install

Download the understrap folder from GitHub or from https://understrap.com
IMPORTANT: If you download it from GitHub make sure you rename the "understrap-master.zip" file just to "understrap.zip" or you might have problems using child themes!
Upload it into your WordPress installation theme subfolder: /wp-content/themes/
Login to your WordPress backend
Go to Appearance → Themes
Activate the Understrap theme

npm install

Open your terminal
Change to the directory where you want to add Understrap
Type npm install understrap

WordPress.org install

Open your WordPress backend
Click on "Appearance -> Themes"
Hit the "Add new" button
Search for "Understrap"
Hit the "install" button
Activate the theme

Developing With npm, postCSS, Rollup, SASS and BrowserSync

This theme uses sass and postCSS to handle compiling all of the styles into one style sheet. The theme also includes rollup.js to handle javascript compilation and minification. These choices are based on the same libraries and npm commands used in Bootstrap. In addition, it comes with Browser Sync to handle live reloading while you develop.

Confused by All the CSS, SCSS, and SASS Files?

Some basics about the files that come with Understrap:

The theme itself uses the /style.css file only 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 and its minified little brother /css/theme.min.css file(s) provides all styles. It is composed of different SCSS sets and one variable file, all imported at /src/sass/theme.scss
Your design goes into: /src/sass/theme.
- Override Bootstrap by addind your variables to the /src/sass/theme/_theme_variables.scss
- Add your custom styles to the /src/sass/theme/_theme.scss file
- Or add other .scss files into it and @import it into /src/sass/theme/_theme.scss.

The same goes for Javascript. Just add your javascript to /src/js/custom-javascript.js and let rollup.js handle the rest.

Installing Dependencies

Make sure you have installed Node.js and Browser-Sync (optional) on your computer globally
Then open your terminal and browse to the location of your Understrap copy
Run: $ npm install

Running

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

npm run watch

Or, to run with Browser-Sync:

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

module.exports = {
	"proxy": "localhost/", // Change here
	"notify": false,
	"files": ["./css/*.min.css", "./js/*.min.js", "./**/*.php"]
};

then run:

npm run watch-bs

Block Editor (Gutenberg) Support

As of version 1.0.0, Understrap supports the block editor. The theme include "Bootstrap" styles automatically for default blocks like tables, captions, and blockquotes. Even further, the theme automatically parses your Bootstrap variables to load your custom color palette into the block editor, ensuring that your color choices match the front-end of the site.

Note: Wide- and full-width blocks will not work with the sidebar templates. They'll simply display in a normal width. They will work, however, with any full width templates or if sidebars are globally disabled in the customizer.

How to Use the Built-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.

RTL styles?

Add a new file to the themes root folder called rtl.css. Add all alignments to this file according to this description: https://codex.wordpress.org/Right_to_Left_Language_Support
