Well, some of you may have been waiting for my second part of the Wordpress vs Blogger review. But, I was sidetracked by a much more ambitious project - merging the dynamic Bootstrap web framework with Blogger. I knew initially that this would be quite a challenge to get it right - and was I correct in that assumption.

So just what is Bootstrap? You can go over to their site and read up, but, at a very high level it is designed as a starter kit for dynamic web UI layouts that utilize CSS and Javascript for a great user experience. If you've seen sites like this one, or this other one - you'll see how Bootstrap can be beautifully extended. In the case of Blogger almost all of their templates are very static and were designed in the 2005-2010 time frame. In the last few years the web has exploded with new, dynamic web frameworks that have reactive interactivity without page refreshes.

The easy path to my task would have been to strip out the entire Blogger template and add Bootstrap in its place as some of these template providers have done. But, if you read my Best Blogger Templates article you know that I am a stickler for keeping Google Blogger as pure to its original intent of a dynamic layout and user substitution of design elements vs a copy-paste of some Wordpress or other template like Bootstrap and just getting it to work.

If you want to try this I've at least laid down a path that will get you past the hardest parts (let me just say I spent days trying to get some of the Bootstrap basics up!)  The key to merging templates is trying to navigate the structures and naming collisions so that both can work. Some of the functionality simply won't work directly in certain cases (such as the header image gadget). But, a creative Javascript programmer could solve some of these small problems - and, in the interest of time I needed to get the basics completed. If you want to try this you must understand web page html basics or otherwise you'll be lost. So, let's get started.

Stripping Out Blogger Templates

The first step is to pick a basic Blogger template and strip out a significant portion of the layout without damaging the Blogger functionality. I chose the Simple template as a the easiest path. What we'll be doing is removing most of the CSS, div tags and Variables to reduce the Blogger template down to its essential layout components so that both the Layout editor and Template editor can still work. (In many external Blogger template seller sites that have modified templates for sale or are free, the designers just strip away everything and render the Blogger editors basically useless).

This might be the hardest part of this tutorial for you. So, be aware you might want to practice on a test blog first. Remember, the goal is to keep Blogger functionality (template design and layout gadgets). Given that, the first step is to set the template to it's simplest form.  Be sure you started with the basic white Simple template. Choose the 'Template' main menu item and then click the 'Customize' button:

Set the template to the simplest single page and column layout pressing the 'Layout' menu like this and press the 'Apply to Blog' button on the upper right:

Go 'Back to Blogger' and now select the 'Edit HTML' button. You will now be within your template. Find the section near the top called <b:skin> and expand it by clicking on the small black arrow next to it. Using your mouse highlight everything from line 27 down to about line 488 in my example (your line number might be slightly different) down to the ]]></b:skin> section and delete it - insuring you don't delete the ]]></b:skin> tag itself. The starting line you highlight must start with the <Group tag as show in my image. (Note: we're keeping the first few lines of the skin for later work). We're deleting all of the template's CSS here:

Press the 'Save Template' button. If you made an error the template editor will let you know. Next, find the <b:template-skin> section and expand it in the editor. Remove all of the CSS between the <![CDATA[ line and the ]]> line (but not removing those 2 lines) like this:

Press the 'Save Template' button again.

Next, we're going to remove the core template <div> tags that are outside the gadgets (note that gadgets themselves contain <div> tags as well but we'll keep those for now).  This is a very tricky step but you'll find that the template editor is your friend here. As you remove <div> tags the editor will highlight the ending </div> tags that are mismatched.

The key to this step is that certain elements of the template need to stay in place so that the layout editor continues to function. The best way to do this is to remove small sets of <div> tags and then try to save to find which ending </div> tags to remove. The first set to remove is everything just after the Navbar gadget up to the <header> tag (the first tag should be <div class='body-fauxcolumns'>):

You'll have to try and keep saving the template after you delete this section above until you find all of the ending </div> tags to remove farther down in the template (be sure to keep the ending </header> tag. Continue to remove sections of <div> tags being very careful to keep any parts called <b:section and the lines in-between to the ending </b:section like this:

You're going to keep doing this through the template until all <div>s are gone by continually saving and removing (but keeping any div tags that are within a <b:widget section). Now that you've completed this step your template is now fully clean but should be able to still be functional in the main menu Layout section (try adding and deleting some Gadgets to verify). Also, the 'Customize' button should still work partially to add and remove right or left hand columns or footers in the 'Layout' section without any issues. Be sure to verify this. Congrats! You now have a Bootstrap ready template.

Adding Bootstrap Components to Blogger

Bootstrap utilizes the JQuery Javascript engine for part of its functionality as well as its own Javascript library. What we'll be doing in this step is adding the javascript library links and the Bootstrap CSS to the template.  One BIG problem to solve in this step is the naming collision of the Bootstrap CSS components with the Blogger names. I will get to that in a bit.

Meanwhile, just add these library components just before the ending </body> tag of your clean template:

<!-- jQuery (necessary for Bootstrap's JavaScript plugins) --> 
<script src='https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js'/>
<!-- Include all compiled plugins (below), or include individual files as needed -->
<script crossorigin='anonymous' integrity='sha384-0mSbJDEHialfmuBBQP6A4Qrprq5OVfW37PRR3j5ELqxss1yVqOtnepnHVP9aJ7xS' src='https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js'/>

like this:

Go ahead and save the template being sure to test that you can preview it without any errors (yes, the template will look a bit odd at this point.)

Next step is to add the header information. Copy these  lines and paste them just after the <head> tag right at the top of the template as shown below:

    <meta charset='utf-8'/>
    <meta content='IE=edge' http-equiv='X-UA-Compatible'/>
    <meta content='width=device-width, initial-scale=1' name='viewport'/>
    <!-- The above 3 meta tags *must* come first in the head; any other head content must come *after* these tags -->

    <!-- Bootstrap -->
    <!-- <link crossorigin='anonymous' href='https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css' integrity='sha384-1q8mTJOASx8j1Au+a5WDVnPi2lkFfwwEAa8hDDdjZlpLegxhjVME1fgjWPGmkzs7' rel='stylesheet'/> -->
    <!-- HTML5 shim and Respond.js for IE8 support of HTML5 elements and media queries -->
    <!-- WARNING: Respond.js doesn't work if you view the page via file:// -->
    <!--[if lt IE 9]>
      <script src="https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js"></script>
      <script src="https://oss.maxcdn.com/respond/1.4.2/respond.min.js"></script>
    <![endif]-->

like this:

These are the necessary mods for the mobile and browser compatibility settings. You've probably noticed that I commented out the bootstrap.min.css code here. This is because of the naming collisions with Blogger I noted earlier. What we're going to do is to get a copy of this CSS code, modify it and then place it in the <b:skin> section of Blogger's template.

Modifying Bootstrap's CSS Code

The best way to do this is to copy the Bootstrap CSS link of the bootstrap.min.css above (click on this line to get to the link).  You should see the Bootstrap CSS in a new browser window now.  Do a Select All and copy/paste this code into a text editor. Use the editor to do a global replace of any text with 'navbar' to 'navbar2'. You can see where my first instance of 'navbar' was changed to 'navbar2' here (there are over 50 more instances):

The reason we're doing this is due to the 'navbar' name in Blogger. It is different than Bootstrap's navbar so we have to alter the Bootstrap name. What this implies is that any time you add a Bootstrap navbar to Blogger you'll have to alter all of the navbar names to navbar2 which I'll show in a bit.

Next, just copy the modified CSS code from your text editor and paste it into your Blogger's <b:skin> section just like this:

Save your template now and make sure it works again by previewing it, checking if the Layout editor works and the template designer can alter your columns and footers.

Congratulations!! A ton of work has paid off! You now have a first functioning Bootstrap template.

Add the Bootstrap Navbar and Jumbotron

"Wait a minute!" you might ask! "I don't see anything yet!"  That's correct. You now need to add the basic Bootstrap HTML to your template. I'm assuming you understand HTML fairly well so that you can add the Bootstrap components you desire. I'm just going to place an example here by starting with the Bootstrap navbar and jumbotron sections.

One of the best parts of Bootstrap's capabilities is the flexible navbar and upper image contained in the template when you view it on different devices. This is a very simple HTML addition now - just adding the <nav class section and <div class='jumbotron' section. Let's start with the navbar.

I've chosen a dynamic navbar from the Bootstrap example webpage. You could easily choose a different one if you like how it functions. All you need to do is copy and paste the HTML code. The Bootstrap dynamic navbar scales nicely when you view the Blogger page on a full PC screen or on a small smartphone.  This particular code needs to be pasted in the Blogger template just after the <body tag and the Blogger navbar and this section right at the top of the template as shown below:

    <!-- Bootstrap navbar -->
      <nav class='navbar2 navbar2-default'>
        <div class='container-fluid'>
          <div class='navbar2-header'>
            <button aria-controls='navbar2' aria-expanded='false' class='navbar2-toggle collapsed' data-target='#navbar2' data-toggle='collapse' type='button'>
              <span class='sr-only'>Toggle navigation</span>
              <span class='icon-bar'/>
              <span class='icon-bar'/>
              <span class='icon-bar'/>
            </button>
            <a class='navbar2-brand' href='#'>Project name</a>
          </div>
          <div class='navbar2-collapse collapse' id='navbar2'>
            <ul class='nav navbar2-nav'>
              <li class='active'><a href='#'>Home</a></li>
              <li><a href='#'>About</a></li>
              <li><a href='#'>Contact</a></li>
              <li class='dropdown'>
                <a aria-expanded='false' aria-haspopup='true' class='dropdown-toggle' data-toggle='dropdown' href='#' role='button'>Dropdown <span class='caret'/></a>
                <ul class='dropdown-menu'>
                  <li><a href='#'>Action</a></li>
                  <li><a href='#'>Another action</a></li>
                  <li><a href='#'>Something else here</a></li>
                  <li class='divider' role='separator'/>
                  <li class='dropdown-header'>Nav header</li>
                  <li><a href='#'>Separated link</a></li>
                  <li><a href='#'>One more separated link</a></li>
                </ul>
              </li>
            </ul>
            <ul class='nav navbar2-nav navbar2-right'>
              <li class='active'><a href='./'>Default <span class='sr-only'>(current)</span></a></li>
              <li><a href='../navbar-static-top/'>Static top</a></li>
              <li><a href='../navbar-fixed-top/'>Fixed top</a></li>
            </ul>
          </div><!--/.nav-collapse -->
        </div><!--/.container-fluid -->
      </nav> 

notice that I have altered any Bootstrap reference of the word 'navbar' to 'navbar2' in this code - (look for the section I've boxed in below to see where you should paste the navbar code underneath):

That's it! Now take a peek at the top of your template.  It should look like this:

The best part is now when you alter your browser window down to a small size you should see the upper right menu button drop down the very same list that was horizontal in the wide screen mode:

At this point the actual menu items would have to be altered directly in the HTML code above to add your menu items and associated page links. Connecting it to the Blogger template editor would be tougher and I just wanted to get you based functionality first here.

Finally, in this tutorial I'll also add the jumbotron component. This is a large image that sits just under the navbar (if you have one) and will dynamically scale and scroll when you adjust your browser window. I found a simple image out on the Flickr Creative Commons for this particular test. If you've read my previous posts you need to add your desired image to Blogger's image pool first. All you have to do is add your image to a new Post, save it and publish it. Then revert it back to draft status. Your image is then saved on the Blogger network no matter if the post is active or not. Go back into your post and view the HTML. The image will have a long link like this - https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjGh7SnRZ1d9UDKPE4cc3zj1TygXzYIwdFXtBFpIN4Tk0Z_2p2jMcb88XxwRTPkqy6itvWs8wQ6UpCo4_ktpoF-lt-bdg3SPwUCl2N4loHAPX9cHaTe91bimPoTEs_X2TjreNqx6BvBN2k/s320/BloggervsWordpress.jpg.

Once you've uploaded the image you can now use this in the Bootstrap jumbotron component. What you'll want to do is to copy and paste this code just after the <header> tag and before the <b:section class='header' in the Blogger template like this:

     <header>

    <!-- Main jumbotron for a primary marketing message or call to action -->
    <div class='jumbotron'>
      <div class='container'>
        <h1>Hello, world!</h1>
        <p>This is a template for a simple marketing or informational website. It includes a large callout called a jumbotron and three supporting pieces of content. Use it as a starting point to create something more unique.</p>
        <p><a class='btn btn-primary btn-lg' href='#' role='button'>Learn more</a></p>
      </div>
    </div>

      <b:section class='header' id='header' maxwidgets='1' name='Header' showaddelement='no'>

Go ahead and save the template but not that this won't show the image yet. We'll place the image link into a jumbotron CSS section.  This CSS section needs to be copied and pasted into the <b:template-skin part of the Blogger template:

.jumbotron {
    position: relative;
    background: #000 url("https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiyA0FmhlnBSFMKnBed_KmrHlVulVjEbczfGNMDjJOf4hLVbfTeXsaEtHderbp0bp5GcnJ0mO12jgsZRB5Uz3YMQ6qfR7ckAyGNRhsu4Q31DnhLv7RroHWEh2V9_yuv1BwcSwzFv9JsYMS9/s1600/NPineMain.jpg") center center;
    width: 100%;
    height: 100%;
    background-size: cover;
    overflow: hidden;
    color: #fff;
}

In this code you can see the link to my guitar image with the url() section in the background. Be sure to replace your link with mine. Here is where I pasted it:

Save your template. We are just about ready to go. The last thing I want you to do is to add the single Bootstrap  <div class='container'> section around everything under the </header> tag in the Blogger template.  Just add it right after the </header> tag and place an ending </div> tag just after the </footer> tag at the end of the template.

That's it for Part 1!!!  You now have a template with a scalable navbar and jumbotron image!  The entire image and template should slide dynamically up and down when the menu is selected in a small mobile view.  Here are my examples and here is a link you can try: dyplate.blogspot.com. Enjoy!!!

And now a mobile view:
