Customizr, what for ?

WordPress is probably one of the best tools to publish and organize content (CMS) in the world, but a website is not only about content, it’s also about design. That’s where the Customizr theme comes in. The Customizr theme is a tool to bring design to your WordPress content.

When developing the Customizr theme, the first step has been to analyze the most frequent requests from my clients and to understand what makes a layout and design engaging for their visitors. Everyone has a specific design need for his or her website. A small pizza restaurant in Rome will obviously not target the same audience of a large private equity company based in San Francisco. But ultimately, the goal of those two very different websites will still converge in the way that they need to present what they do in the most impactful and engaging way, hoping that a visitor will stay as long as possible, and could even be converted into more than a simple visitor : client, follower, recurrent visitor, etc.

The Customizr theme has been developed with universal design principles in mind that will work on most websites,for example :

  1. Logo upload
  2. Featured content (page, post, images) with sliders, featured pages
  3. Easily select and apply beautiful typographies with a live Google Fonts picker
  4. Apply a specific page layout on a page or post basis


Under the hood, a the Customizr theme has been coded to ensure that your website :

  1. Loads fast (read more about the performance settings) ,
  2. Adapts to any devices (responsive) : desktop, tablets, smartphones,
  3. Is compatible with all the major browsers,
  4. Is optimized for SEO


A reliable and safe theme

The Customizr theme is the result of more than 5 years of development and improvements. Probably all possible mistakes, issues, errors, and¬†plugin collisions have been reported, and for most of them fixed! (thanks to a vibrant community of users ūüôā )

Since there’s no such thing as bug-free software, we have our eyes peeled for any unknown or future bugs. If you have a question about Customizr, chances are it has already been asked and answered in the 10 000 + topics on the Customizr theme forum.

The Customizr theme is hosted on the theme’s repository. To be accepted on this repository, a theme has to respect detailed requirements and guidelines to ensure maximum security for its users, and to be compliant with WordPress best coding practices. Each time a new version is submitted, it goes through a control process with hundreds of automated checks, a final manual test, and an approval made by an administrator of the theme review team.


Made to be customizable

Since its inception, the Customizr theme has been designed to be easily customizable and extendable.

Live customizations with the WordPress Customizer

¬†skin The first level of customization can be accessed from the WordPress admin area, in Appearance > Customize. There you‚Äôll find a set of options allowing you to change your site’s appearance¬†in real-time. With 135 + different options to choose from, the theme offers endless possible combinations of unique webdesigns.

CSS customizations

For designers, Customizr offers a live Custom CSS  field to test and apply simple style modifications. For more complex style changes, the Customizr theme is child-theme ready and there’s no limit to overriding and extending the default CSS stylesheets of the theme.
