Glassy Music Player Codepen

Procedure

Step 1 - HTML Structure:
Declare the document type and set the language to English. Include metadata in the head, such as character set, viewport settings, and page title. Import Google Fonts ('Belanosima' and 'Rubik+Vinyl'). Create a body with a background image and 'Belanosima' font..

Step 2 - Music Player Container (div class="darksoul-music"):
Style a container for the music player with dimensions, background, and a glassy effect. Use flexbox for proper alignment and apply keyframe animations for a subtle movement.

Step 3 - Media Player Section (div class="music-mediaplayer"):
Include an audio element with the source set to your music file. Display the song title, an input range slider, and control icons.

Step 4 - Range Slider Styling (input type="range"):
Style the range slider with a custom appearance. Add a cubic-bezier animation for the slider thumb.

Step 5 - Media Player Icons (div class="media-player-icons"):
Use flexbox to align play, pause, backward, and forward icons. Apply styles, including a hover effect for better visibility.

Step 6 - Music Banner (div class="music-banner"):
Create a banner with a semi-transparent background, rounded border, and shadow. Insert an image for the album cover.

Step 7 - JavaScript Script:
Implement JavaScript functions to play/pause audio. Set an interval to simulate the range slider movement.

Step 8 - Responsive Design (@media):
Adjust the music player's dimensions and styles for screens with a width of 500px or less.
