Bootstrap: align input with button

Twitter Bootstrap 4

In Twitter Bootstrap 4, inputs and buttons can be aligned using the input-group-prepend and input-group-append classes (see https://getbootstrap.com/docs/4.0/components/input-group/#button-addons)

Group button on the left side (prepend)

<div class="input-group mb-3">
  <div class="input-group-prepend">
    <button class="btn btn-outline-secondary" type="button">Button</button>
  </div>
  <input type="text" class="form-control">
</div>

Group button on the right side (append)

<div class="input-group mb-3">
  <input type="text" class="form-control">
  <div class="input-group-append">
    <button class="btn btn-outline-secondary" type="button">Button</button>
  </div>
</div>

Twitter Bootstrap 3

As shown in the answer by @abimelex, inputs and buttons can be aligned by using the .input-group classes (see http://getbootstrap.com/components/#input-groups-buttons)

Group button on the left side

<div class="input-group">
  <span class="input-group-btn">
    <button class="btn btn-default" type="button">Go!</button>
  </span>
  <input type="text" class="form-control">
</div>

Group button on the right side

<div class="input-group">
   <input type="text" class="form-control">
   <span class="input-group-btn">
        <button class="btn btn-default" type="button">Go!</button>
   </span>
</div>

This solution has been added to keep my answer up to date, but please stick your up-vote on the answer provided by @abimelex.

Twitter Bootstrap 2

Bootstrap offers an .input-append class, which works as a wrapper element and corrects this for you:

<div class="input-append">
    <input name="search" id="search"/>
    <button class="btn">button</button>
</div>

As pointed out by @OleksiyKhilkevich in his answer, there is a second way to align input and button by using the .form-horizontal class:

<div class="form-horizontal">
    <input name="search" id="search"/>
    <button class="btn">button</button>
</div>

The Differences

The difference between these two classes is that .input-append will place the button up against the input element (so they look like they are attached), where .form-horizontal will place a space between them.

-- Note --

To allow the input and button elements to be next to each other without spacing, the font-size has been set to 0 in the .input-append class (this removes the white spacing between the inline-block elements). This may have an adverse effect on font-sizes in the input element if you want to override the defaults using em or % measurements.


Just the heads up, there seems to be special CSS class for this called form-horizontal

input-append has another side effect, that it drops font-size to zero


Bootstrap 5

<div class="input-group">
  <input type="text" class="form-control">
  <button class="btn btn-outline-secondary" type="button">Go</button>
</div>

Bootstrap 3 & 4

you may use the input-group button property to apply the button direct to the input-field.

<div class="input-group">
  <input type="text" class="form-control">
  <span class="input-group-btn">
    <button class="btn btn-default" type="button">Go!</button>
  </span>
</div><!-- /input-group -->

Take a look at BS4 or BS5 Input-Group doc for many more examples.

example for bs3 input group button


Use .form-inline = This will left-align labels and inline-block controls for a compact layout

Example: http://jsfiddle.net/hSuy4/292/

<div class="form-inline">
<input type="text">
<input type="button" class="btn" value="submit">
</div>

.form-horizontal = Right align labels and float them to the left to make them appear on the same line as controls which is better for 2 column form layout. 

(e.g. 
Label 1: [textbox]
Label 2: [textbox]
     : [button]
)
