Bootstrap Input Box

Overview

The majority of the elements we work with in documents to record site visitor information are offered by the

<input>

tag.

You are able to easily add to form directions via incorporating text message, tabs, as well as button groups on either side of textual

<input>

-s.

The separate sorts of Bootstrap Input Group are identified by value of their type attribute.

Next, we'll describe the received styles regarding this kind of tag.

Message

<Input type ="text" name ="username">

Undoubtedly the absolute most typical type of input, which has the attribute

type ="text"

, is utilized each time we need the user to deliver a elementary textual info, because this particular feature does not allow the access of line breaks.

Whenever providing the form, the details inserted by the site visitor is easily accessible on the server side throughout the

"name"

attribute, utilized to determine every related information contained in the request parameters.

In order to get access to the details inputed if we manage the form having some kind of script, to validate the web content as an example, it is required to have the elements of the value property of the object in the DOM. ( read more)

Parole

<Input type="password" name="pswd">

Bootstrap Input Class that accepts the

type="password"

attribute is very similar to the text type, except that it does not present really the text message inserted at the hand of the site visitor, on the other hand prefer a group of figures "*" or yet another depending upon the browser and operational system .

Basic Bootstrap Input Box good example

Place one add-on or button on either side of an input.

<div class="input-group">
  <span class="input-group-addon" id="basic-addon1">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-describedby="basic-addon1">
</div>
<br>
<div class="input-group">
  <input type="text" class="form-control" placeholder="Recipient's username" aria-describedby="basic-addon2">
  <span class="input-group-addon" id="basic-addon2">@example.com</span>
</div>
<br>
<label for="basic-url">Your vanity URL</label>
<div class="input-group">
  <span class="input-group-addon" id="basic-addon3">https://example.com/users/</span>
  <input type="text" class="form-control" id="basic-url" aria-describedby="basic-addon3">
</div>
<br>
<div class="input-group">
  <span class="input-group-addon">$</span>
  <input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
  <span class="input-group-addon">.00</span>
</div>
<br>
<div class="input-group">
  <span class="input-group-addon">$</span>
  <span class="input-group-addon">0.00</span>
  <input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
</div>

Proportions

Add in the related form scale classes to the

.input-group

itself and information located in will automatically resize-- no urgency for reproducing the form regulation scale classes on each feature.

<div class="input-group input-group-lg">
  <span class="input-group-addon" id="sizing-addon1">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-describedby="sizing-addon1">
</div>
<br>
<div class="input-group">
  <span class="input-group-addon" id="sizing-addon2">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-describedby="sizing-addon2">
</div>

Set any kind of checkbox or radio feature inside an input group’s addon as an alternative to of text.

Checkbox button option

The input element of the checkbox option is pretty often employed as we have an solution that can possibly be registered as yes or no, such as "I accept the terms of the user contract", or perhaps "Keep the active procedure" in documents Login. ( more info)

Even though commonly used having the value

true

, you can easily certify any value for the checkbox.

<div class="col-lg-6">
    <div class="input-group">
      <span class="input-group-addon">
        <input type="checkbox" aria-label="Checkbox for following text input">
      </span>
      <input type="text" class="form-control" aria-label="Text input with checkbox">
    </div>
</div>

Radio button feature

In the event we desire the user to choose only one of a set of methods, we are able to employ input components of the radio option.

Every time there is more than just one particular feature of this style along with the similar value in the name attribute, only one can possibly be chosen.

<div class="col-lg-6">
    <div class="input-group">
      <span class="input-group-addon">
        <input type="radio" aria-label="Radio button for following text input">
      </span>
      <input type="text" class="form-control" aria-label="Text input with radio button">
    </div>
</div>

Multiple addons

Plenty of add-ons are upheld and could be crossed with checkbox and radio input versions.

<div class="row">
  <div class="col-lg-6">
    <div class="input-group">
      <span class="input-group-addon">
        <input type="checkbox" aria-label="Checkbox for following text input">
      </span>
      <span class="input-group-addon">$</span>
      <input type="text" class="form-control" aria-label="Text input with checkbox">
    </div>
  </div>
  <div class="col-lg-6">
    <div class="input-group">
      <span class="input-group-addon">$</span>
      <span class="input-group-addon">0.00</span>
      <input type="text" class="form-control" aria-label="Text input with radio button">
    </div>
  </div>
</div>

Input group: additional buttons variations

<Input type ="button" name ="show_dialogue" value ="Click here!">

The input element along with the

type="button"

attribute delivers a button inside the form, but this specific tab has no straight use upon it and is regularly employed to cause activities when it comes to script implementation.

The tab content is identified with value of the

"value"

attribute.
