This HTML code snippet helps you to create an alarm clock. The clock interface is divided into three sections: WeekDays, TimeHolder, and AlarmInput. The WeekDays section displays the days of the week. The TimeHolder section shows the time in a digital format, including hours, minutes, and seconds. The Time Format section provides controls to set the time format (12hr or 24hr), display AM/PM, and start, pause, or stop the alarm clock.

Finally, the AlarmInput section allows users to enter the number of seconds for the alarm to go off. The code also includes span elements and div elements with classes and IDs that will be styled with CSS.

How to Create Html Alarm Clock Code

First of all, load the Font Awesome 5 CSS for icons and Google digital fonts by adding the following CDN links into the head tag of your HTML document.

<link rel='stylesheet' href='https://use.fontawesome.com/releases/v5.5.0/css/all.css'>
<link href="https://fonts.googleapis.com/css?family=Orbitron|Text+Me+One" rel="stylesheet">

Now, create the HTML structure for the alarm clock as follows:

<div class="container">
            <div class="ClockHolder">

                <div class="WeekDays">
                    <span>sat</span>
                    <span>sun</span>

                    <span>tue</span>
                    <span>wed</span>
                    <span>thu</span>
                    <span>fri</span>
                </div>

                <div class="TimeHolder">
