Bootstrap Input Style

Introduction

The majority of the components we utilize in applications to catch site visitor data are coming from the <input> tag.

You may with ease add to form regulations simply by incorporating text, buttons, or tab groups on each side of textual <input>-s.

The many different kinds of Bootstrap Input Group are established due to the value of their option attribute.

Next, we'll describe the approved types with regard to this specific tag.

Text message

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

Quite possibly easily the most typical type of input, which owns the attribute type ="text", is put to use each time we desire the user to give a elementary textual details, due to the fact that this feature does not enable the access of line breaks.

Every time sending the form, the data inputed by the site visitor is easily accessible on the server side throughout the "name" attribute, used to determine every single relevant information contained in the request parameters.

To have access to the details typed in anytime we deal with the form along with some type of script, to validate the information as an example, it is necessary to get the elements of the value property of the object in the DOM.

Security password

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

Bootstrap Input Form that gets the type="password" attribute is quite similar to the text type, apart from that it does not reveal exactly the message inserted by the user, on the other hand instead a group of signs "*" or another being dependent on the web browser and working system .

Standard Bootstrap Input Text 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">

</div>
<br>
<label for="basic-url">Your vanity URL</label>
<div class="input-group">

</div>
<br>
<div class="input-group">

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