Source Code

Step 1 (HTML Code):

To start, create the basic HTML structure for your video player. This includes elements such as the <video> tag to embed the video, buttons for play/pause, volume control, progress bar, etc.


Let's break down the HTML code step by step:


1. <!DOCTYPE html>: This declaration specifies the document type and version of HTML being used, in this case, HTML5.


2. <html lang="en">: This opening tag defines the start of the HTML document, with the specified language set to English ("en").


3. <head>: This section contains meta-information about the HTML document, such as character encoding, viewport settings, and the title of the page.


  • <meta charset="UTF-8">: Specifies the character encoding of the document to UTF-8, which supports a wide range of characters.
  • <meta name="viewport" content="width=device-width, initial-scale=1.0">: Defines the viewport settings for the device's screen width and initial zoom level.
  • <title>Custom HTML5 Video Player</title>: Sets the title of the HTML document displayed in the browser tab.
  • <link rel="stylesheet" href="styles.css">: Links an external CSS file named "styles.css" to style the HTML elements.

4. <body>: This section contains the visible content of the HTML document.


  • <h1>Video Player</h1>: Displays a heading "Video Player" at the top of the page.
  • <div class="video-wrapper">: This div contains the video player and its controls.
  • <div class="video-container" id="video-container">: This div wraps the HTML5 video element and provides a container for styling purposes.
  • <video controls id="video" preload="metadata" poster="//cdn.jsdel....jpg">: Defines a video element with controls for play/pause, with an ID of "video". It preloads only the metadata of the video and displays a poster image before the video starts loading.
  • <source src="//cdn.jsdelivr.n..mp4" type="video/mp4">: Specifies the video source file in MP4 format.
  • <div class="play-button-wrapper">: This div contains the play button overlay.
  • <div title="Play video" class="play-gif" id="circle-play-b">: This div displays a play button icon.
  • <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 80 80">: Defines an SVG image for the play button icon.

5. <script src="script.js"></script>: Links an external JavaScript file named "script.js" to handle any interactive behavior or functionality related to the video player.

Step 2 (CSS Code):

Once the HTML structure is in place, style your video player using CSS. Customize the appearance of controls, player layout, and overall design to match your website's theme.


Let's break down the CSS code step by step:


1. html: Styles applied to the HTML element.


  • box-sizing: border-box;: Sets the box-sizing property to border-box, which includes padding and border in the element's total width and height.
  • font-family: "YouTube Noto", Roboto, Arial, Helvetica, sans-serif;: Specifies the font family to be used for text content within the HTML document.
  • height: 100%;: Sets the height of the HTML element to 100% of its containing element.

2. *, *::before, *::after: Styles applied to all elements, pseudo-elements before and after.


  • box-sizing: inherit;: Inherits the box-sizing property from the parent element.
  • margin: 0;: Sets margin to 0 for all elements.
  • padding: 0;: Sets padding to 0 for all elements.

3. body: Styles applied to the body element.


  • height: 100%;: Sets the height of the body element to 100% of its containing element.
  • background-color: #b6c3f0;: Sets the background color of the body to a light blue shade.

4. h1: Styles applied to all h1 elements.


  • color: #00053b;: Sets the text color of h1 elements to a dark blue shade.
  • text-align: center;: Centers the text horizontally within the container.
  • margin-top: 40px;: Sets a top margin of 40 pixels for h1 elements.

5. .video-container: Styles applied to elements with the class "video-container".


  • width: 640px;: Sets the width of the container to 640 pixels.
  • border-radius: 4px;: Rounds the corners of the container.
  • margin: 0 auto;: Centers the container horizontally within its parent element.
  • position: relative;: Establishes a positioning context for absolutely positioned children.
  • display: flex;: Displays the container as a flex container.
  • flex-direction: column;: Arranges flex items vertically.
  • justify-content: center;: Centers flex items vertically within the container.
  • box-shadow: 0px 8px 20px rgba(0, 0, 0, 0.4);: Adds a box shadow effect to the container.

6. .play-button-wrapper: Styles applied to elements with the class "play-button-wrapper".


  • position: absolute;: Positions the element absolutely within its containing element.
  • top: 0; left: 0; right: 0; bottom: 0;: Stretches the element to cover its entire containing element.
  • display: flex; align-items: center; justify-content: center;: Centers the content vertically and horizontally within the element.
  • width: 100%; height: auto;: Sets the width to 100% and adjusts height automatically.
  • pointer-events: none;: Disables pointer events on the element.

7. #circle-play-b: Styles applied to the element with the ID "circle-play-b".


  • cursor: pointer;: Changes the cursor to a pointer when hovering over the element.
  • pointer-events: auto;: Allows pointer events on the element.

8. .play-button-wrapper #circle-play-b svg: Styles applied to the SVG element within the play button wrapper.


  • width: 100px; height: 100px;: Sets the width and height of the SVG element to 100 pixels.
  • fill: #fff; stroke: #fff;: Sets the fill and stroke color of the SVG path to white.
  • cursor: pointer;: Changes the cursor to a pointer when hovering over the SVG element.
  • background-color: rgba(0, 0, 0, 0.2);: Sets the background color of the SVG element to a semi-transparent black.
  • border-radius: 50%;: Rounds the corners of the SVG element, making it a circle.
  • opacity: 0.9;: Sets the opacity of the SVG element to 90%.
html {
  box-sizing: border-box;
  font-family: 'YouTube Noto', Roboto, Arial, Helvetica, sans-serif;
  height: 100%;
}

*,
*::before,
*::after {
  box-sizing: inherit;
  margin: 0;
  padding: 0;
}

body {
  height: 100%;
  background-color: #b6c3f0;
}

h1 {
  color: #00053b;
  text-align: center;
  margin-top: 40px;
}

.video-container {
  width: 640px;
  border-radius: 4px;
  margin: 0 auto;
  position: relative;
  display: flex;
  flex-direction: column;
  justify-content: center;
  box-shadow: 0px 8px 20px rgba(0, 0, 0, 0.4);
}
.video-container .video-wrapper {
  width: 100%;
  height: 100%;
  display: flex;
  justify-content: center;
  align-items: center;
}
.video-container video {
  width: 100%;
  height: 100%;
  border-radius: 4px;
}

.play-button-wrapper {
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  display: flex;
  align-items: center;
  justify-content: center;
  width: 100%;
  height: auto;
  pointer-events: none;
}
.play-button-wrapper #circle-play-b {
  cursor: pointer;
  pointer-events: auto;
}
.play-button-wrapper #circle-play-b svg {
  width: 100px;
  height: 100px;
  fill: #fff;
  stroke: #fff;
  cursor: pointer;
  background-color: rgba(0, 0, 0, 0.2);
  border-radius: 50%;
  opacity: 0.9;
} 

Step 3 (JavaScript Code):

Next, add play/pause functionality to your video player using JavaScript. Let's break down the JavaScript code step by step:


1. const video = document.getElementById("video");


  • This line selects the video element on the webpage using its id attribute and assigns it to the variable video.

2. const circlePlayButton = document.getElementById("circle-play-b");


  • This line selects the play button (assumed to be circular) on the webpage using its id attribute and assigns it to the variable circlePlayButton.

3. function togglePlay() { ... }


  • This is a function named togglePlay that toggles the play/pause state of the video. If the video is paused or ended, it will play the video; otherwise, it will pause the video.

4. circlePlayButton.addEventListener("click", togglePlay);


  • This line adds an event listener to the play button. When the play button is clicked, it calls the togglePlay function to toggle the play/pause state of the video.

5. video.addEventListener("playing", function () { ... });


  • This line adds an event listener to the video element for the "playing" event. When the video starts playing, it executes the function, which sets the opacity of the play button to 0, effectively hiding it.

6. video.addEventListener("pause", function () { ... });


  • This line adds an event listener to the video element for the "pause" event. When the video is paused, it executes the function, which sets the opacity of the play button back to 1, making it visible again.
const video = document.getElementById("video");
const circlePlayButton = document.getElementById("circle-play-b");

function togglePlay() {
	if (video.paused || video.ended) {
		video.play();
	} else {
		video.pause();
	}
}

circlePlayButton.addEventListener("click", togglePlay);
video.addEventListener("playing", function () {
	circlePlayButton.style.opacity = 0;
});
video.addEventListener("pause", function () {
	circlePlayButton.style.opacity = 1;
});
