I am trying to have a centered main content div along with a right sidebar using Bootstrap 3.0.
I have tried the following code to achieve this.
BootPly
But when i resize the browser to shorter width, the sidebar gets pushed down and also the main content get wider. Is this behavior expected of bootstrap ? Do i need to add col-xs* to accommodate the shorter width ?
I am wondering if this is the correct way to achieve this design ?
Thanks !
Yes, it is default behaviour. Bootstrap 3 was built with "mobile first" in mind, so the layout is responsive by default. You can achieve this effect by writing a custom grid and not using the Bootstrap column classes, like col-sm-6 and so on.
<div class="container">
<div class="row">
<div class="col-md-12">
<div class="content">
Main Content
</div>
<div class="sidebar">
Side bar
</div>
</div>
</div>
</div>
Then write some css. This is just an example, and you should customise to fit your own needs.
.sidebar { width: 33.3%; }
.content { width: 66.6%; }
You can fit two columns on the smallest screen size, but it's unlikely that this is what you are after. On small screens there's very little space for any substantial content to fit into two columns.
<div class="col-xs-6">
Main Content
</div>
<div class="col-xs-6">
Side bar
</div>
You are indeed correct that this is a feature of bootstrap :) You're also correct on using .col-xs-* to achieve your planned design. To add to what you're trying to do, (just in case you haven't tried this already) you can also combine the grid classes in order to accommodate the different screen sizes.
Here's an example:
<div class="row">
<div class="col-md-8 col-sm-6 col-xs-12">
</div>
<div class="col-md-4 col-sm-6 col-xs-12">
</div>
</div>
Goodluck! :)

I am a complete beginner and I am learning Bootstrap. I want to know how to determine which column system I need to use in my website. Suppose I have a row with 3 columns. Now I have 3 options.
Option 1:
<div class="row">
<div class="col-md-4">
</div>
<div class="col-md-4">
</div>
<div class="col-md-4">
</div>
</div>
Option 2:
<div class="row">
<div class="col-lg-4">
</div>
<div class="col-lg-4">
</div>
<div class="col-lg-4">
</div>
</div>
Option 3:
<div class="row">
<div class="col-sm-4">
</div>
<div class="col-sm-4">
</div>
<div class="col-sm-4">
</div>
</div>
Now my question is, As I want my website to be responsive which class I need to apply. I want my website to render properly irrespective of device selected. I understood that they are meant for different devices. Does that mean, I need to write 3 different css style code (I doubt it). So, what shall I put in my code?
P.S: I saw this link SO LINK and I understood it. But still I am confused, what to put in my code? Shall I put sm,lg or md?
These define the width of the screen at which the layout will collapse. For example, in .col-md-, the layout will be horizontal until the screen width is less than 970px, at this point, the layout will collapse. However, if you use .col-lg-, the layout will be horizontal until the screen width is less than 1170px, then it will collapse.
Bootstrap has 4 breakpoints, .col-xs-, .col-sm-, .col-md- and .col-lg-. You should use these depending on the content of the div. The best way to become familiar is to play around with each one and notice that the layout collapses at different points for each one when you decrease the width of your window. So to answer the question, you should choose whichever one collapses correctly for the content of your div. Hope this helps.
For a more detailed guide on the bootstrap grid system, take at look at this: https://www.w3schools.com/bootstrap/bootstrap_grid_system.asp
I found it helpful to get a good understanding.
I generally use col-md prefix, so I guess your first option would work quite fine: col-md-4.
To add to the other suggestions you've received, remember that you can apply multiple Bootstrap column classes to the same div.
For example say you wanted 3 equal width columns on a wide viewport. Then as the viewport narrows this changes to one full width header with two equal width columns below, and on smartphones all three divs are stacked vertically, then you might use something like
<div class="container">
<div class="row">
<div class="col-lg-4 col-md-12">column1
</div>
<div class="col-lg-4 col-md-6">colmun2
</div>
<div class="col-lg-4 col-md-6">column3
</div>
</div>
</div>
See this live https://codepen.io/panchroma/pen/EwVwpw
Or you might want to change the relative widths of your 3 columns at different viewports
<div class="row">
<div class="col-lg-6 col-md-4">
</div>
<div class="col-lg-3 col-md-4">
</div>
<div class="col-lg-3 col-md-4">
</div>
</div>
Or you might want to hide one of the columns at narrower viewports
<div class="row">
<div class="col-md-4">
</div>
<div class="col-md-4">
</div>
<div class="col-md-4 hidden-sm hidden-xs">
</div>
</div>
The important thing is that you can mix and match your classes to achieve the responsive behaviour that you need.
Once you get the hang of the grid sizing options you might also want to check out how to reorder columns. What often happens is that you need to have a different column order on desktop and mobile, and there will probably be times when you want to offset columns as well.
Good luck!
I'm making a web app which should list objects gathered from json in a tile-based list (kinda like shopping store), where every tile is a div. What is the best way to do that in Bootstrap ? I'm using Angular and I want to do it with a help from ng-repeat directive. If the number of divs exceed view area, scroll bar should appear.
This is graphical view, how I want it to look like.
What is actually the best way to implement that?
Thanks in advance.
You can use the regular bootstrap grid system
<div class="row">
<div class="col-md-4">.col-md-4</div>
<div class="col-md-4">.col-md-4</div>
<div class="col-md-4">.col-md-4</div>
<div class="col-md-4">.col-md-4</div>
<div class="col-md-4">.col-md-4</div>
<div class="col-md-4">.col-md-4</div>
</div>
The width of the page is 12 units, so divs of width 4 will give you 3 columns. If you keep adding divs with a total width of more than 12, it will be placed in diferent rows.
In the example I gave you, you should get exacly 2 rows with 3 elements in each.
<div class=container>
<div class="row">
<div class="col-sm-4" ng-repeat="tile in tiles">
<div class="panel panel-default">
<div class="panel-header">
{{tile.header}}
</div>
<div class="panel-body">
{{tile.body}}
</div>
</div>
</div>
</div>
</div>
Something like this maybe? I use col-sm-4, that way 3 tiles can be visible in a row. When the screen becomes smaller, then 700-something, it will be layed upon eachother instead.
Use bootstraps grid system. Put all the divs in a container with .row class and mark the ng-repeated div with .col-sm-4 Add max-width: and overflow: auto to your container so you get the scrolling.
I'm having a bit of a hickup with bootstrap. Here's the deal:
I have a table made with divs with 4 fields, but I want them to have different alignments when they are being viewed on a mobile phone. Let me put the code of my table here to help explain:
<div class="table-responsive container text-center">
<div class="visible-md-block visible-lg-block row">
<div class="col-xs-4 col-md-3"><strong>From</strong></div>
<div class="col-xs-4 col-md-3"><strong>Points</strong></div>
<div class="col-xs-4 col-md-3"><strong>To</strong></div>
<div class="col-xs-12 col-md-3"><strong>Description</strong></div>
</div>
<div class="row">
<div class="col-xs-4 col-md-3">John doe</div>
<div class="col-xs-4 col-md-3">+20</div>
<div class="col-xs-4 col-md-3">Jane doe</div>
<div class="col-xs-12 col-md-3">Test Description</div>
</div>
</div>
There. If you are aware of bootstrap, you'll by now have realized the type of layout it will adopt. but I'll explain anyways:
When the viewport goes to a phone screen size I want the description column to go below the other ones.
Thing is, on that phone screen size I want to put the alignment diffrently from the centered one (that I defined on the table).
I want the "From" column aligned to the left, the "Points" column center aligned and the "To" column right aligned and the "Description" column to be center aligned while on larger viewports I want them to have a diffrent alignment. How would I pull such an effect off?
Also tips on weather I should use a table or keep using divs for this type of responsive coding are welcome :p
To accomplish the behavior you're after, you're likely going to need to come up with your own class, give it the majority of behaviors that col-xs-4 and col-md-3 have, and add your own home brewed styling to make the Description column fall below the other three for certain #media queries, etc.
media all and (max-width: 1000px) {
.custom-col-xs-4 {
float: left;
}
.costom-col-xs-4-lower {
clear: both;
}
}

I'm trying to position sidebar on the right side in a site based on Bootstrap grid.
Well, this is very simplified layout that I've made - jsFiddle
I admit it's not the good use of bootstrap classes (rows etc.) but it works.
The problem is: the sidebar html code must be under the text and content (because of SEO), so it must be somehow positioned next to content (class .content).
I tried positioned it as an relative element but didn't have any luck.
The text in .text div does not have static height, it will change
The .content will have same height every time
Is this more what you were after?
<div class="container">
<div class="row">
<div class="col-xs-9 pull-right">
<div class="col-xs-12 content">Main</div>
<div class="col-xs-12 text">Lorem</div>
</div>
<div class="col-xs-3 sidebar pull-left">
<p>sidebar</p>
</div>
</div>
</div>
jsFiddle
Basically I've split your entire container 3 to 9, and then made your 'content' and 'text' blocks children of the '9' column. I then applied both the pull-left and pull-right class to the relevant containers.
I also fixed up your HTML a bit as it was missing a div tag. I also got rid of some of the text to make the code more readable to me!
I'm a beginner in css and I have a little problem. I tested different methods to handle a responsive 4 div grid with css, and I failed.
I want to responsively arrange the 4 divs as an grid with 2 columns and, if the display is to narrow it should be floating to a one column layout.
Here is a sketch of the responsive grid:
Here is a simple responsive grid with 4 div boxes in plain CSS and HTML it aranges from two to one columns when the browser width becomes smaller :
DEMO (resize the result window to see the effect)
Note that the max-width value on the #container is set to 450px so that 2 blocks + their margin can fit by width in two colmuns.
When the widow is smaller than 450px the width of the #container adapts to the window width and as the block can't fit anymore, they rearage to one column.
#container {
text-align: center;
max-width: 450px;
margin: 0 auto;
}
.block {
width: 200px;
height: 200px;
margin: 10px;
display: inline-block;
background: #00CC99;
}
<div id="container">
<div class="block">1</div>
<div class="block">2</div>
<div class="block">3</div>
<div class="block">4</div>
</div>
You may want to check out Bootstrap, and specifically their Grid System. You can easily accomplish what you want with that. Otherwise, you'd want to look into writing your own CSS Media Queries to handle the different screen sizes.
Here's a JSFiddle showing how this can be achieved using Bootstrap. Just drag the side of the Result container to make it smaller and you can see the blocks shift. This may need some tweaking but it should get you going.
<div class="row">
<div class="col-sm-2 col-sm-offset-3 col-xs-12">
<div class="block">1</div>
</div>
<div class="col-sm-3 col-xs-12">
<div class="block">2</div>
</div>
<div class="col-sm-2 col-sm-offset-3 col-xs-12">
<div class="block">3</div>
</div>
<div class="col-sm-3 col-xs-12">
<div class="block">4</div>
</div>
</div>
In the above code, I'm creating a Bootstrap Grid which uses 12 columns. You can specify the column width at different screen sizes, for example the class col-sm-2 is saying use 2/12ths of the width for small screen sizes, then offset it 3 to center it. col-xs-12 says to use the full width for extra small screen sizes (essentially moving each block to its own row for extra small screens). Note the row class as well which is also Bootstrap specific.
Hopefully this helps!
Bootstrap is a great tool to do this as the above answerer said. Bootstrap allows you to position items in a grid layout (as you want).
Another way to do this is create media queries in css that will take effect when the browser has a smaller or larger min-width.
I recommend using Bootstrap as all of the heavy lifting is done for you and you would just have to make small tweaks to ensure it looks like you want it to.
