Video: Dealing with grid changes

So we've migrated our site from Bootstrap 2 to Bootstrap 3 by installing the new CSS and the new JavaScript files. And the first thing you probably want to fix is the basic layout of your pages, and that's actually extremely easy to do. Before we do that, I'm going to show you how I coded this page because it's important to understand. If you look at my index.php page, you'll see that I'm using PHP components here. To make sure that I separate the part of my content from my layout, and that's going to make it really easy to understand what's changed. Because if you look at this page, there's only a few tags that you need to worry about.

Dealing with grid changes

So we've migrated our site from Bootstrap 2 to Bootstrap 3 by installing the new CSS and the new JavaScript files. And the first thing you probably want to fix is the basic layout of your pages, and that's actually extremely easy to do. Before we do that, I'm going to show you how I coded this page because it's important to understand. If you look at my index.php page, you'll see that I'm using PHP components here. To make sure that I separate the part of my content from my layout, and that's going to make it really easy to understand what's changed. Because if you look at this page, there's only a few tags that you need to worry about.

So for example, we've got the main content right here and we've got the sidebar content in this section and each one of these different parts are separated into different articles or aside items. So what we have in this HTML is essentially two sections and each of the sections has a band with different numbers. Now, if we want to update that into the new version of Bootstrap, you know that what we need to do is change the class from span and whatever number, then add col and then col-lg-1, which is really all wee need to do to update our layouts.

So, let's go ahead and do that. This is the index page, and I'm going to change this span8 to col col-lg, and then 8. And then do the same thing for this other span, and this one's going to be changed, of course, to a number 4 and that should be it. So let me go ahead and save this page and go into our website and refresh. And you'll see that my columns return just fine. So it's really just that easy, it's going to be a lot of these very simple types of changes that you need to do in your layout. And, if you do something like what I've done here, use PHP to separate your content from your layout, it's going to be really easy for you to find this kind of issue and resolve it when you upgrade to the new version.

All you have to do is find anywhere were you see a span tag and change it to the new layouts that appear in Bootstrap 3.
