Video: Looking out for class changes

Something you need to watch out for when you upgrade an old site to the new version of Bootstrap is that one of the classes in Images has changed a little bit in the new version. So, you may have noticed that these pictures don't look like polaroids, which is what they're supposed to look like. Now if we take a look at the manual, you'll see that in the old Bootstrap, the class for creating this effect right here was called img-polaroid. In the new version of Bootstrap, this is now called img-thumbnail. So if you've got any Polaroids that you're using, you need to make sure that you watch out for that class change.

Looking out for class changes

Something you need to watch out for when you upgrade an old site to the new version of Bootstrap is that one of the classes in Images has changed a little bit in the new version. So, you may have noticed that these pictures don't look like polaroids, which is what they're supposed to look like. Now if we take a look at the manual, you'll see that in the old Bootstrap, the class for creating this effect right here was called img-polaroid. In the new version of Bootstrap, this is now called img-thumbnail. So if you've got any Polaroids that you're using, you need to make sure that you watch out for that class change.

Now, in my website, I was using JavaScript to generate those, so notice that right here, what I'm doing is, I'm just saying any photos from last year class in the aside section that is an image I want you add the class img-polaroid. So I need to modify that to thumbnail, and Save it, and let me go back into my website, and you'll see that it's refreshed to the proper version. Now, this is going to be different on your website because you may not be using JavaScript at classes to things. But it's still something you're going to have to watch out for. If you're using any classes of img-polaroid , they have to be updated to img-thumbnail in the new version of Bootstrap.
