Testimonials

We use Understrap for most of our WordPress projects. We find it is a great starting point for just about any design.

It takes a lot of the initial setup of a theme out of the equation allowing us to start building sooner.

It is easy to customise to the needs of our clients as well as build our own custom sections that work well with the theme as it includes Bootstrap 4.

It is the perfect theme to build beautiful responsive sites. I highly recommend this to anyone and everyone!

We've been using UnderStrap for years. It easily saves us 10 hours of work on custom web builds.

The best part is fast-loading pages with zero bloat which is perfect for SEO.

About UnderStrap

Holger - The Developer of UnderStrap
Holger, Developer of UnderStrap

"I´am a Frontend Dev and UX Designer working with WordPress and responsive frameworks daily. Instead of starting again and again from scratch I decide to combine my two most used tools into one:"

Underscores starter theme

Based on the "best-practices" starter theme Underscores, or just "_s" - Made by Automattic, the company behind WordPress.

Bootstrap 4 Grid framework

Uses Bootstrap 3 Bootstrap 4 for markup and CSS styles - THE industry standard for responsive and mobile friendly websites.

SASS

Utilizes the SASS sources from all assets as well as own SASS files. Makes it easy to replace colors, fonts, stylings etc.


npm

Comes with npm support to manage all the dependencies. Just one command in your terminal is needed to update all assets.


Gulp

Comes with Gulp as task runner and one pre-made gulpfile.js with some default tasks. For example to compile SASS to CSS.
