Source Code
Step 1 (HTML Code):
Start by creating the HTML structure for your webpage. Ensure you have a container element that will host the pulsating effect. This could be a section, div, or any other suitable HTML tag.
How to:
- Open your preferred code editor.
- Create an HTML file.
- Define the structure of your webpage, including the container element.
Let's break down the HTML code:
1. <!DOCTYPE html>: This declaration defines the document type and version of HTML being used. In this case, it's HTML5.
2. <html lang="en">: This tag represents the root of the HTML document, and the lang attribute is set to "en" indicating that the document is written in English.
3. <head>: This section contains meta-information about the HTML document, such as character set, viewport settings, and links to external resources.
- <meta charset="UTF-8">: Specifies the character encoding for the document as UTF-8, which is a widely used character encoding for the web.
- <meta http-equiv="X-UA-Compatible" content="IE=edge">: This meta tag is used to set the document mode and engine compatibility for Internet Explorer. It's often set to "IE=edge" to ensure the highest compatibility.
- <meta name="viewport" content="width=device-width, initial-scale=1.0">: This meta tag sets the viewport properties for responsive web design. It ensures that the width of the page is equal to the device width and sets the initial zoom level to 1.0.
- <title>Pulse Effect</title>: Sets the title of the HTML document to "Pulse Effect," which is typically displayed in the browser's title bar or tab.
- <link rel="stylesheet" href="styles.css">: This line links an external stylesheet (styles.css) to the HTML document. The stylesheet contains CSS rules that define the visual appearance of the page.
4. <body>: This section contains the actual content of the HTML document.
- <div class="pulse"></div>: A <div> element with a class of "pulse." This is used for a pulsating effect.
Step 2 (CSS Code):
Now, let's add some style to your container element. Apply basic styling properties like width, height, and background color. This will serve as the canvas for our pulse animation. Define keyframes for the pulsating effect, adjusting the size, opacity, or color at different intervals. This creates the illusion of a pulsating animation.
How to:
- Create a new CSS file.
- Link the CSS file to your HTML document.
- Style the container element with the desired properties.
- In your CSS file, define @keyframes with specific percentages.
- Adjust the properties of the container element within each keyframe.
Let's break down the CSS code step by step:
1. Styling for the body element:
- Background Color: Sets the background color of the entire webpage to a dark shade (#1f1d2b).
- Margin: Sets the margin of the body to zero, removing any default spacing.
- Height: Sets the height of the body to 100% of the viewport height (100vh), ensuring the content takes up the full height of the browser window.
- Flexbox: Uses Flexbox to center the content both vertically and horizontally.
2. Styling for elements with the class .pulse:
- Background Color: Sets the background color of elements with the class .pulse to a light shade (#ffd791).
- Border Radius: Rounds the corners of the element to create a circular shape, as the value is set to 50%.
- Animation: Applies the pulse-effect animation to the element, with a duration of 2 seconds and set to repeat infinitely.
- Height and Width: Sets the height and width of the element to 80 pixels each, creating a circular shape.
3. Keyframes Animation named pulse-effect:
- Keyframes Definition: Defines a set of keyframes for the animation named pulse-effect.
- 0% Keyframe: At the start (0%), the element is slightly scaled-down (90% of its original size) and has a box shadow with a certain color (#ffba44).
- 70% Keyframe: At 70% of the animation, the element is fully scaled up (100% of its original size) and has a larger box shadow with a red tint (rgba(255, 82, 82, 0)).
- 100% Keyframe: At the end (100%), the element returns to being slightly scaled down, and the box shadow disappears.
body {
background-color: #1f1d2b;
margin: 0;
height: 100vh;
display: flex;
align-items: center;
justify-content: center;
}
.pulse {
background-color: #ffd791;
border-radius: 50%;
animation: pulse-effect 2s infinite;
height: 80px;
width: 80px;
}
@keyframes pulse-effect {
0% {
transform: scale(0.9);
box-shadow: 0 0 0 0 #ffba44;
}
70% {
transform: scale(1);
box-shadow: 0 0 0 10px rgba(255, 82, 82, 0);
}
100% {
transform: scale(0.9);
box-shadow: 0 0 0 0 rgba(255, 82, 82, 0);
}
} Final Output:
