Change Asp.net or HTML TextBox background color on focus using jQuery

Introduction:  In this article I am going to share how to highlight HTML input or Asp.Net textbox on focus using focusin and focusout  methods of jquery   i.e. Change background color on focus. This trick also works for HTML textarea and asp.net multiline textbox.
Change background color of Asp.net or HTML TextBox on focus using jQuery
In previous articles i explained how to Highlight asp.net or html textbox on mouse hover using jquery and Jquery to show hide password characters in textbox on checkbox check uncheck and How to Show jquery tooltip message on mouse over on asp.net controls  and How to Show tool tip message using css and html in asp.net controls and Show validation guidelines in web forms using javascript in asp.net

Implementation: Let’s create an example to demonstrate the concept.

HTML Source
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
    <title></title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script type="text/javascript">
        $(document).ready(function () {
            $('.txt').focusin(function () {
                $(this).css("background-color", "#fff4d8");
            });
            $('.txt').focusout(function () {
                $(this).css("background-color", "#FFFFFF");
            });
        });
    </script>
</head>
<body>
    <form id="form1" runat="server">
        <div>
            <fieldset style="width:270px;">
                <legend>Highlight textbox on focus</legend>
                <table>
                    <tr>
                        <td>User Name:</td>
                        <td>
                            <asp:TextBox ID="txtUserName" CssClass="txt" runat="server"></asp:TextBox></td>
                    </tr>
                    <tr>
                        <td>Password:</td>
                        <td>
                            <asp:TextBox ID="txtPassword" TextMode="Password" CssClass="txt" runat="server"></asp:TextBox>                         
                        </td>
                    </tr>
                </table>
            </fieldset>
        </div>
    </form>
</body>
</html>

Highlight HTML input controls: If you want to implement the same for HTML textbox or then just replace the asp.net textbox  controls with html input controls as mentioned below and rest is same:
<input id=" txtUserName " type="text" class="txt" />
<input id=" txtPassword " type="password" class="txt"/>

Description: I have assigned a CSS class "txt" to the controls that I want to highlight on getting focus and through jquery I accessed the controls by the assigned class and changed the background color.
