How to make Label and Button control Responsive using CSS in ASP.Net

Please share your html. Let me see how you are applying css.

HI Power , 

try following script to make responsive and add CssClass="form-control" in their ASP controls, which would you like to use ... example in button.

 <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
    <script type="text/javascript" src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/js/bootstrap.min.js"></script>
    <link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap.min.css" />

 <asp:Button ID="Button1" runat="server" Font-Bold="true" ForeColor="White" CssClass="form-control" BackColor="#428bca" 
                                    Width="30px" Text="button" ></asp:Button>

Check you have not added&nbsp CssClass="form-control" for button and label.

I ended up adding the following css and it works for me. I am sharing this incase it helps others. Thank you.

@media all and (max-width: 600px) {
    .responsive-width {
        font-size: 2vw;
    }
