Twitter Bootstrap 4 WordPress Starter Theme for Developers

Creating a WordPress Theme using the Bootstrap 4 Blog Template Example

When using Bootstrap 4 as a basis for WordPress one of the biggest work items is the integration with different plugins, widgets and template pages. This work usually requires a lot of filters and rolling your own bespoke methods to manipulate the WordPress output to use Bootstrap 4 HTML markup. I don’t say this as a negative, that IS the game with WordPress and Bootstrap: you can do whatever you want, with whatever you want and DevDmBootstrap4 wouldn’t be possible without it.

Looking at the Bootstrap 4 examples page, you can see there is a whole showcase of examples showing you “what is possible” for a motivated individual with Bootstrap 4 at their finger tips. This is easy stuff if you have a static website. However, folding these examples into WordPress is a little more involved and takes some knowledge of WordPress systems to create something that is actually usable.

You can guess my goal here: Show you how to make these Bootstrap 4 examples into actual functioning WordPress child themes using DevDmBootstrap4. I say this with the caveat that these will NOT be perfect. I will however get you to something functional. I encourage you to take the reigns, make it your own, expand on what I have done, share it for others and help us all be better developers.

The first example we will start with is, The Blog Template.

Step one in the conversion process is to study the Bootstrap 4 example but imagine it was powered by WordPress instead of being static HTML. With the Blog Template example it was clear this was going to be the Home Page of the WordPress site, there is need for a featured post system, a sidebar, a text widget with a background option for the sidebar and a custom nav walker to get the nav bar links to be powered by a WordPress menu.

Fortunately for us DevDmBootstrap4 is built EXACTLY for this type of work. A simple view source in our browser will give us everything we need to break this example down and create a WordPress theme that actually works. So sit back and let’s take a journey through the process of creating a child theme for DevDmBootstrap4. We are going to touch a lot of different areas of the WordPress development skill set: widget areas, filters, hooks and the customizer API just to name a few.

In this blog series I will walk you through the thought process and what I did to create the final child theme, which you can download here.

Let’s get started…

First I downloaded a new devdmbootstrap4-child theme to get started. I changed the Theme Name and Description in the meta tags of style.css to reflect the project. I saw that the Blog Template example was using a blog.css file so I copied the entire contents and just pasted it into style.css. You could download blog.css and send it through the enqueue system. You should, if this is going to be a production level project.

The first tricky bit was the Google font in the HTML header.

<!-- Custom styles for this template -->
<link href=",900" rel="stylesheet">

I choose to add this as an @import in the style.css so I wouldn’t have to mess with the header.php at all from the original devdmbootstrap4 parent theme.

@import url(',900');

Remember, this (parent / childtheme relationship) is a system that is 100% centered around duplicating files from the parent devdmbootstrap4 into a childtheme to override it. The less we have to do, the better. You can enqueue Google fonts as well but I wanted things to be simple.

Here is a full guide on Google Font integration into WordPress that I have used in the past.

In the next post we will talk about building the HTML header and footer from the Blog Template Example. In the mean time download the completed child theme and take a look for yourself and try it out.

Download the Blog Template Example Child Theme

DevDmBootstrap4 v1.71

The theme has been updated to v1.71. The Download Page is updated with links. The WordPress Theme directory version has been updated as well.

About this Update:

  • Updated to the latest pull of Bootstrap. It is currently at version 4.1.1
  • Fixed sprint_f vs sprintf in utilities.php devdmbootstrap4_header_background() method. The issue being that sprint_f is nothing and it was breaking the theme when using a header background. This was pretty silly and I have no idea how it slipped through everything. Sorry if it caused anyone some trouble.

DevDmBootstrap4 v1.7

The theme has been updated to v1.7. The Download Page is updated with links. We skipped v1.6 this time as I wanted to try and get it submitted to the Theme Directory before I actually generated a release. My Theme Reviewer had more changes and Bootstrap 4.1 has become available, so it is time for a new release.

About this Update:

WordPress Theme Directory Status

Could v1.7 be the one that gets us finally listed?! Only the Shadow Knows…

We made it. Officially listed!

DevDmBootstrap4 v1.5

The theme has been updated to v1.5. The Download Page is updated with links.

About this Update:

  • Some small updates to searchform.php for proper esc attributes to get on the WordPress Theme Directory.
  • Adding in links and a changelog in the readme.txt/md.
  • Updating licenses to be consistent with GPLv3.

WordPress Theme Directory Status

We are close. These changes should be what we need to get officially listed.

DevDmBootstrap4 v1.4

The theme has been updated to v1.4. The Download Page is updated with links.

About this Update:

This update is fairly straight forward.

  • Bootstrap 4 assets (css/js) update as of 3.27.18
  • Updating Archive Post Types to use h2 vs h1 tags for SEO improvements.
  • Added some descriptions to the DevDmBootstrap4 options in the WordPress Customizer.
  • Updated the and en_US.po files with these new description strings.

WordPress Theme Directory Status

Still no traction on our approval ticket. I have submitted this version of the theme. I will poke them again.

DevDmBootstrap4 v1.3

A new theme update wills itself into existence today, v1.3. Head on over to the Download Page to grab it.

About this Update:

  • Includes the latest pull (as of 02/15/18) from the Bootstrap Git Repository (v4-dev) branch.
  • Various escaping and translation fixes to strings and variables in the theme files.
  • SEO improvements to the post list pages vs single posts/pages. Any post list style pages like archive.php or index.php will have the Site Title in the header by an <h1> tag. Single post/pages will have the title of the page/post be the <h1> and theSite Title will be downgraded to an <h2>. This should help with search engine indexing.
  • Regenerated the devdmbootstrap4.pot file and the  / en_US.po files. You can find links to the language files on the Translations page.
  • The devdmbootstrap-scss-child theme has also had the latest compiled Bootstrap 4 pull integrated into it.

WordPress Theme Directory Status

A lot of the code changes in this update were the result of v1.2 being shutdown for admittance to the WordPress Theme Directory. I guess it has been a while since I have played that game. Some new tools have emerged that are automating a lot of the Theme Checks. One such tool called, “Theme Sniffer” was actually really helpful and there were clearly some security flaws with the Theme that needed to be addressed. I have submitted version 1.3 to the Theme Directory but it is missing our SEO tweaks and latest Bootstrap 4 update. Things don’t move very fast over there. I anticipate v1.4 of the Theme to be in sync with the Theme directory. If we get approved. Maybe I can re-submit v1.3 as it is on GitHub. I’ll try.

Knowledge Base

We have a new tab at the top here called Knowledge Base. This is where I will post my fielded questions from Twitter and email

“In brightest day, in blackest night, No evil shall escape my sight. Let those who worship evil’s might Beware my power –Green Lantern’s light!”

DevDmBootstrap4 v1.2

A new theme update hits today, v1.2. Head on over to the Download Page to grab it.

About this Update:

  • Includes the latest pull from the Bootstrap Git Repository (v4-dev) branch.
  • Bug Fix for not displaying categories on pages.
  • CSS fix for removing rounded corners on the featured post image.
  • Some PHP clean up.

Introduction of the devdmbootstrap4-scss-child theme.

The default child theme devdmbootstrap4-child doesn’t include any of the SCSS code. It is just a simple child theme to get you started coding outside of the parent. This new child theme includes the full suite of SCSS and compiled CSS used by the parent theme devdmbootstrap4. So you are getting the entire Bootstrap 4 SCSS code and the additions for WordPress that devdmbootstrap4 brings to the table. This child theme’s functions.php actually dequeues the parent stylesheet and enqueues the compiled CSS bundled within itself.

This translates to COMPLETE control for the savvy developer who wants to get in there to tweak, extend, and compile their own version of a Bootstrap 4 WordPress compatible theme.

WordPress Theme Directory Submission.

I’ve submitted the theme officially to the WordPress theme directory. I will update with any news as it becomes available.

The theme documentation on the site here is being worked on daily.

I’m still working through all the different theme file pages but most of the important stuff is fleshed out to give you any assistance you might require when developing your child theme.

As always, my office is open! Leave a comment here, email me or dm me on Twitter.

DevDmBootstrap4 v1.1

It is time true believers, to open the gates and get WordPress into the Bootstrap 4 world.

[Download it Here]

I’ve been working on DevDmBootstrap4 since Bootstrap 4 Alpha was announced. With the success of DevDmBootstrap3 I wanted to make sure I was ready when Bootstrap 4 officially came out of Beta, and here we are. Bootstrap 4 release blog post announcement.

I have had to rebuild and retool some things on the migration from Bootstrap 3.x to Bootstrap 4.x, but those who are familiar with DevDmBootstrap3 will find that DevDmBootstrap4 follows the same file patterns and code structure as its predecessor.

I’ll be working on bringing up more child-themes and fleshing out the documentation on the site here in the coming months.

You can sign up for the Newsletter on the sidebar to get updates. I’m going to be sending those around the 1st of every month to give a state of the theme, what new content is available and what has been updated. I’ve got BIG plans for child-themes this year, including full Gutenberg support.

We are not on the WordPress Theme Directory yet but you can find everything on GitHub or the Download page.
