It is not possible in input but you can change the background color to red if it is not in range using CSS only., Constructing a secret villain base - best ways for covert short-range air transport? ,Asking for help, clarification, or responding to other answers.

You can't do this with a regular <input type="text"> or <textarea> element, but with a normal element (like <div> or <p>) made contenteditable, you have all the freedoms of html/css formatting.

<div contenteditable>

This sets the color of every <p> block so that its color attribute matches the current value of the color input, which is referred to using event.target.,Here's an example that watches changes over time to the color value:,As is the case with other <input> types, there are two events that can be used to detect changes to the color value: input and change. input is fired on the <input> element every time the color changes. The change event is fired when the user dismisses the color picker. In both cases, you can determine the new value of the element by looking at its value.

<input type="color" value="#ff0000">

More complex layouts can also be created with the grid system.,As shown in the previous examples, our grid system allows you to place any number of .cols within a .row or .form-row. They’ll split the available width equally between them. You may also pick a subset of your columns to take up more or less space, while the remaining .cols equally split the rest, with specific column classes like .col-7.,Validation styles are available for the following form controls and components:

<form>
   <div class="form-group">
      <label for="exampleInputEmail1">Email address</label>
      <input type="email" class="form-control" id="exampleInputEmail1" aria-describedby="emailHelp">
      <small id="emailHelp" class="form-text text-muted">We'll never share your email with anyone else.</small>
   </div>
   <div class="form-group">
      <label for="exampleInputPassword1">Password</label>
      <input type="password" class="form-control" id="exampleInputPassword1">
   </div>
   <div class="form-group form-check">
      <input type="checkbox" class="form-check-input" id="exampleCheck1">
      <label class="form-check-label" for="exampleCheck1">Check me out</label>
   </div>
   <button type="submit" class="btn btn-primary">Submit</button>
</form>

This problem can be solved by using input tags having the same “name” attribute value that can group multiple values stored under one name which could later be accessed by using that name. To access all the values entered in input fields use the following method:

var input = document.getElementsByName('array[]');
