I have been using twitter bootstrap for a year, its the one of those things which -"just works" . With release of twitter bootstrap3 its become even better and awesome with its mobile first approach. But i am not able to understand how to use it properly with mobile first approach.
Earlier there was .span* and .offset* class but now there are .col-xs-* .col-md-* .col-sm-* .col-lg-* and .col-xs-offset-* .col-md-offset-* classes respectively. Even now 'it-just-works' using .col-md-* i want to know the right way to use all these classes so as to not just use them but use them correctly to get most out of bootstrap3.
Thanks.

Currently I'm using Bootstrap 3 for web development, how I'm using the Grid system is,
<div class="container">
<div class="row">
<div class="col-md-9"> <%--this for 9X3 grid--%>
<div class="row">
<div class="col-md-6"> <%--this for 6X6 inner grid--%>
</div>
<div class="col-md-6">
</div>
</div>
</div>
<div class="col-md-3">
</div>
</div>
</div>
I found (a) Bootstrap's own documentation helpful here, but also a (b) lynda.com topic in migrating to Bootstrap 3. Specifically, see "Dealing with grid changes"

I've been using bootstrap 4 on my angular 12 project for a while, and today I've upgraded to bootstrap 5.
I know some properties have changed, but I've read that the grid system is identical.
I regularly use "Mix and Match" columns as written in the documentation, for example
<div class="container">
<div class="row">
<div class="col-12 col-sm"></div>
<div class="col-12 col-sm-auto"></div>
<div class="col-12 col-sm"></div>
</div>
</div>
This example it's working very well with Bootstrap v4.* but not on v5.
It is supposed to have only 1 row where the first and third columns try to get all the available space and the second column fits your content.
What I saw on the Chrome DevTools that the col-12 class takes precedence over the col-sm class, even on larger screens.
Any ideas to try to solve this problem?
As I recently answered here, this is a bug that was introduced in 5.0.2 because the order of the column declarations was changed, making col-12 override col-sm on all breakpoints.
Until it's fixed, a workaround in your case would be to simply remove the col-12 (it's not needed since col-12 is the default)...
<div class="container">
<div class="row">
<div class="col-sm">col</div>
<div class="col-sm-auto">col</div>
<div class="col-sm">col</div>
</div>
</div>

I keep bumping into this issue where everyone keeps:
a) wanting to wrap HTML5 semantic tags with divs, and
b) wants to apply class selectors to the divs and not the semantic tags. It's as if people are afraid of slapping classes onto semantic tags for some reason.
For example, I am constantly told that this is "incorrect",
<body class="container">
<header class="row">
<div class="col-md-12"> ...
And something like this is more preferable,
<body>
<div class="container">
<div class="row">
<div class="col-md-12"> ...
And here, where the first example I have the column class in the h2 tag
<div class="row">
<h2 class="col-4 feature">Featured Work</h2>
</div>
But "the correct" way is to add yet another div tag to apply the class,
<div class="row">
<div class="col-4 feature">
<h2>Featured Work</h2>
</div>
</div>
I understand that this might be opinion-based, but I have found that when dealing with HTML5, opinions actually matter since virtually everyone is having issues and there is no other way to hammer out the details without opinions.
I recommend sticking to the
<body>
<div class="container">
<div class="row">
<div class="col-md-12"> ...
format.
If you intend to work with a lot other developers or with bootstrap templates- you will see that the container classes typically nest row class divs.
Since we are talking about markup there is no right answer, but following this convention is strongly recommended.
For consistency
For easy changes to styling & reusability with other projects- this even opens the door to drop-in replacements of css stylesheets from other projects or bootstrap templates. (I have had some surprisingly good results with this).
However, if you insist on giving non-div tags "container" and "col-X" tags, be consistent. I wouldn't recommend it though and would consider any template that follows its own convention to be an indicator of poor code quality.
I'm having a very hard time assigning intelligent class names to my DOM elements.
I feel like the example below is something my CSS commonly devolves into:
<div class="article">
<div class="title-container">
<div class="title>Something fantastic</div>
<div class="sub-title-controls">
<div class="btn-like"></div>
<div class="btn-google-plus-one"></div>
<div class="btn-share"></div>
</div>
</div>
</div>
But then later I'll want to add a different style of "Share" button lower on the page. So I end up doing:
<div class="article">
<div class="title-container">
<div class="title>Something fantastic</div>
<div class="sub-title-controls">
<div class="btn-like"></div>
<div class="btn-google-plus-one"></div>
<div class="btn-share-tiny"></div>
</div>
</div>
</div>
<div>...More stuff...</div>
<div class="btn-share-big"></div>
Then things spiral out of control from there.
I guess what I'm looking for is: Is there any kind of Chicago Manual of Style for CSS? Like when is a <div> really better described as a <section> or <footer>? How do you intelligently name non-visual DIVs that serve as containers?
My CSS is a nightmare after 2 years of coding without structure. Just about given up and gone all inline on this particular project. :) Tips appreciated.
SMACCS is style guide for CSS, and might be exactly what you're looking for. You can buy it, or alternatively much of the content is available free on the site.
Additionally, BEM is a framework developed by the guys at Yandex, which I found useful reading and is used (somewhat) by InuitCSS, which I personally am keen on.
You should find some answers here, in this article titled: What Makes For a Semantic Class Name?.
In a nutshell, when you can, use the new HTML5 tags:
<header></header>
<article></article>
<aside></aside>
<footer></footer>
for your example, it would be better to do something like this :
<div class="btn-share"></div>
...
<div class="btn-share bigBtn"></div>
and only change the size in the bigBtn class.
I have a demo site which is located here to give you an idea of what's going on. If you scroll to the bottom where you see the 9 individual posts they are all laid out properly. How ever if you shrink the screen to anything less then 1232px's youll see that the 7th post breaks away from the others and shifts down.
Now I am using default styles to align them as such, using row and then span4. Can any one explain why this happens? And any way to fix it?
Your span totals should add up to 12. Your example site however adds up to more than 40! I don't think there is any defined behaviour for what should happen if you don't use it as intended.
From Bootstrap homepage
"The default Bootstrap grid system utilizes 12 columns"
So the total of your spans must add to 12 per row. ie.
<div class="row">
<div class="span4">...</div>
<div class="span8">...</div>
</div>
<div class="row">
<div class="span3">...</div>
<div class="span3">...</div>
<div class="span3">...</div>
</div>
<div class="row">
<div class="span7">...</div>
<div class="span3 offset2">...</div>
</div>
I am currently testing out Blueprint to create the layout for a site. So far it has been going great, but now I've run into a problem I'm wondering if there is any elegant solution to.
I am using the default 24 column layout and have a situation where I would like to do something similar to:
<div class="span-8 box">..</div>
<div class="span-8 box">..</div>
<div class="span-8 box last">..</div>
Problem is that the box-class adds a padding which causes the three div's to not fit into the 24 columns.
One "solution" is to use span-7 instead for all three, but this doesn't fill the entire width.
Any ideas?
You can use the class this way:
<div class="span-8">
<div class="box">..</div>
</div>
<div class="span-8">
<div class="box">..</div>
</div>
<div class="span-8 last">
<div class="box">..</div>
</div>
You could change the "span-7" css rule:
...
.span-7 {width:274px;}
...
And change the divs to "span 7".
Simplest thing I could think of :)
