[css] Input widths on Bootstrap 3

Update again: I am closing this question by selecting the top answer to keep people from adding answers without really understanding the question. In reality there is no way to do it with the build in functionality without using grid or adding extra css. Grids do not work well if you are dealing with help-block elements that need to go beyond a short input for example but they are 'build-in'. If that is an issue I recommend using extra css classes which you can find in the BS3 discussion here. Now that BS4 is out it is possible to use the included sizing styles to manage this so this is not going to be relevant for much longer. Thanks all for good input on this popular SO question.

Update: This question remains open because it is about built-in functionality in BS to manage input width without resorting to grid (sometimes they have to be managed independently). I already use custom classes to manage this so this is not a how-to on basic css. The task is in BS feature discussion list and has yet to be addressed.

Original Question: Anyone figure out a way to manage input width on BS 3? I'm currently using some custom classes to add that functionality but I may have missed some non documented options.

Current docs say to use .col-lg-x but that clearly doesn't work as it can only be applied to the container div which then causes all kinds of layout/float issues.

Here's a fiddle. Weird is that on the fiddle I can't even get the form-group to resize.

<form role="form" class="row">
    <div class="form-group col-lg-1">
        <label for="code">Name</label>
        <input type="text" class="form-control">
    </div>

    <div class="form-group col-lg-1 ">
        <label for="code">Email</label>
        <input type="text" class="form-control input-normal">
    </div>

    <button type="submit" class="btn btn-default">Submit</button>
</form>
</div>

ASP.net MVC go to Content- Site.css and remove or comment this line:

input,
select,
textarea {
    /*max-width: 280px;*/
}

Bootstrap uses the class 'form-input' for controlling the attributes of 'input fields'. Simply, add your own 'form-input' class with the desired width, border, text size, etc in your css file or head section.

(or else, directly add the size='5' inline code in input attributes in the body section.)

Bootstrap 3 I achieved a nice responsive form layout using the following:

<div class="row">
    <div class="form-group  col-sm-4">
        <label for=""> Date</label>
        <input type="date" class="form-control" id="date" name="date" placeholder=" date">
    </div>

    <div class="form-group  col-sm-4">
        <label for="hours">Hours</label>
        <input type="" class="form-control" id="hours" name="hours" placeholder="Total hours">
    </div>
</div>

You don't have to give up simple css :)

.short { max-width: 300px; }
<input type="text" class="form-control short" id="...">

In Bootstrap 3

All textual < input >, < textarea >, and < select > elements with .form-control are set to width: 100%; by default.

http://getbootstrap.com/css/#forms-example

It seems, in some cases, we have to set manually the max width we want for the inputs.

Anyway, your example works. Just check it with a large screen, so you can see the name and email fields are getting the 2/12 of the with (col-lg-1 + col-lg-1 and you have 12 columns). But if you have a smaller screen (just resize your browser), the inputs will expand until the end of the row.

You can add the style attribute or you can add a definition for the input tag in a css file.

Option 1: adding the style attribute

<input type="text" class="form-control" id="ex1" style="width: 100px;">

Option 2: definition in css

input{
  width: 100px
}

You can change the 100px in auto

I hope I could help.

I think you need to wrap the inputs inside a col-lg-4, and then inside the form-group and it all gets contained in a form-horizontal..

    <form class="form form-horizontal">
         <div class="form-group">
           <div class="col-md-3">
            <label>Email</label>
            <input type="email" class="form-control" id="email" placeholder="email">
           </div>
         </div>
         ...
     </form>

EDIT: From the Bootstrap 3 docs..

Inputs, selects, and textareas are 100% wide by default in Bootstrap. To use the inline form, you'll have to set a width on the form controls used within.

So another option is to set a specific width using CSS:

.form-control {
    width:100px;
}

Or, apply the col-sm-* to the `form-group'.

If you're looking to simply reduce or increase the width of Bootstrap's input elements to your liking, I would use max-width in the CSS.

Here is a very simple example I created:

    <form style="max-width:500px">

    <div class="form-group"> 
    <input type="text" class="form-control" id="name" placeholder="Name">
    </div>

    <div class="form-group">
    <input type="email" class="form-control" id="email" placeholder="Email Address">
    </div>

    <div class="form-group">
    <textarea class="form-control" rows="5" placeholder="Message"></textarea>
    </div>   

    <button type="submit" class="btn btn-primary">Submit</button>
    </form>

I've set the whole form's maximum width to 500px. This way you won't need to use any of Bootstrap's grid system and it will also keep the form responsive.

I'm also struggled with the same problem, and this is my solution.

HTML source

<div class="input_width">
    <input type="text" class="form-control input-lg" placeholder="sample">
</div>

Cover input code with another div class

CSS source

.input_width{
   width: 450px;
}

give any width or margin setting on covered div class.

Bootstrap's input width is always default as 100%, so width is follow that covered width.

This is not the best way, but easiest and only solution that I solved the problem.

Hope this helped.

<div class="form-group col-lg-4">
    <label for="exampleInputEmail1">Email address</label>
    <input type="email" class="form-control" id="exampleInputEmail1" placeholder="Enter email">
</div>

Add the class to the form.group to constraint the inputs

Current docs say to use .col-xs-x , no lg. Then I try in fiddle and it's seem to work :

http://jsfiddle.net/tX3ae/225/

to keep the layout maybe you can change where you put the class "row" like this :

<div class="container">
  <h1>My form</h1>
  <p>How to make these input fields small and retain the layout.</p>
  <div class="row">
    <form role="form" class="col-xs-3">

      <div class="form-group">
        <label for="name">Name</label>
        <input type="text" class="form-control" id="name" name="name" >
      </div>

      <div class="form-group">
        <label for="email">Email</label>
        <input type="text" class="form-control" id="email" name="email">
      </div>

      <button type="submit" class="btn btn-default">Submit</button>
    </form>
  </div>
</div>

http://jsfiddle.net/tX3ae/226/

I know this is an old thread, but I experienced the same issue with an inline form, and none of the options above solved the issue. So I fixed my inline form like so:-

<form class="form-inline" action="" method="post" accept-charset="UTF-8">
    <div class="row">
        <div class="form-group col-xs-7" style="padding-right: 0;">
            <label class="sr-only" for="term">Search</label>
            <input type="text" class="form-control" style="width: 100% !important;" name="term" id="term" placeholder="Search..." autocomplete="off">
            <span class="help-block">0 results</span>
        </div>
        <div class="form-group col-xs-2">
            <button type="submit" name="search" class="btn btn-success" id="search">Search</button>
        </div>
    </div>
</form>

That was my solution. Bit hacky hack, but did the job for an inline form.

Add and define terms for the style="" to the input field, that's the easiest way to go about it: Example:

<form>
    <div class="form-group">
        <label for="email">Email address:</label>
        <input type="email" class="form-control" id="email" style="width:200px;">
    </div>
    <div class="form-group">
        <label for="pwd">Password:</label>
        <input type="password" class="form-control" id="pwd" style="width:200px">
    </div>
    <button type="submit" class="btn btn-default">Submit</button>
</form>

In Bootstrap 3

You can simply create a custom style:

.form-control-inline {
    min-width: 0;
    width: auto;
    display: inline;
}

Then add it to form controls like so:

<div class="controls">
    <select id="expirymonth" class="form-control form-control-inline">
        <option value="01">01 - January</option>
        <option value="02">02 - February</option>
        <option value="03">03 - March</option>
        <option value="12">12 - December</option>
    </select>
    <select id="expiryyear" class="form-control form-control-inline">
        <option value="2014">2014</option>
        <option value="2015">2015</option>
        <option value="2016">2016</option>
    </select>
</div>

This way you don't have to put extra markup for layout in your HTML.

I do not know why everyone has seem to overlook the site.css file in the Content folder. Look at line 22 in this file and you will see the settings for input to be controlled. It would appear that your site is not referencing this style sheet.

I added this:

input, select, textarea { max-width: 280px;}

to your fiddle and it works just fine.

You should never ever update bootstrap.css or bootstrap.min.css. Doing so will set you up to fail when bootstrap gets updated. That is why the site.css file is included. This is where you can make changes to site that will still give you the responsive design you are looking for.

Here is the fiddle with it working

If you are using the Master.Site template in Visual Studio 15, the base project has "Site.css" which OVERRIDES the width of form-control fields.

I could not get the width of my text boxes to get any wider than about 300px wide. I tried EVERYTHING and nothing worked. I found that there is a setting in Site.css which was causing the problem.

Get rid of this and you can get control over your field widths.

/* Set widths on the form inputs since otherwise they're 100% wide */
input[type="text"],
input[type="password"],
input[type="email"],
input[type="tel"],
input[type="select"] {
    max-width: 280px;
}
