Learn to design a pill loader with HTML and CSS through this detailed guide. Perfect for pharmacy applications.
Table of Contents
A pill loader, also known as a pharmacy loader or capsule loader, is a visual element commonly used in web applications to indicate the progress of tasks. In this tutorial, we'll walk through the process of creating a pill loader from scratch using HTML and CSS.
Source Code
Step 1 (HTML Code):
The first thing we need to do is create our HTML File for the pill loader. We'll start with well-organized markup. After creating the files just paste the following codes into your file. Remember that you must save a file with the .html extension.
Let's break it down step by step:
1. <!DOCTYPE html>: This declaration specifies that the document is an HTML5 document.
2. <html lang="en">: This opening tag marks the beginning of the HTML document and specifies that the language of the document is English.
3. <head>: This section contains meta-information about the document, such as its title, character encoding, and links to external resources like stylesheets.
- <meta charset="UTF-8">: This meta tag specifies the character encoding for the document, ensuring proper display of text characters.
- <meta http-equiv="X-UA-Compatible" content="IE=edge">: This meta tag ensures compatibility with Internet Explorer by instructing it to use the latest rendering engine available.
- <meta name="viewport" content="width=device-width, initial-scale=1.0">: This meta tag sets the viewport properties for responsive web design, ensuring proper scaling on various devices.
- <title>Pill Loader</title>: This sets the title of the webpage, which appears in the browser's title bar or tab.
- <link rel="stylesheet" href="styles.css">: This line links an external stylesheet named "styles.css" to the HTML document, providing styles to be applied to the webpage.
4. <body>: This section contains the visible content of the webpage.
5. <div class="absCenter">: This <div> element with the class "absCenter" serves to center its child elements both vertically and horizontally on the page.
6. <div class="loaderPill">: This <div> represents the container for the loader animation.
7. Inside the .loaderPill div, several nested <div> elements define the structure of the loader animation:
- .loaderPill-anim: Container for the animation.
- .loaderPill-anim-bounce: An element responsible for the bouncing animation.
- .loaderPill-anim-flop: An element responsible for the flopping animation.
- .loaderPill-pill: The actual pill-shaped loader element.
8. <div class="loaderPill-floor">: This <div> represents the floor or base of the loader animation.
9. <div class="loaderPill-floor-shadow"></div>: This <div> represents a shadow effect under the loader.
10. <div class="loaderPill-text">Loading your RX</div>: This <div> contains text indicating that the page is loading, for user feedback.
11. </body>: This tag marks the end of the body section.
12. </html>: This closing tag marks the end of the HTML document.
Step 2 (CSS Code):
Next, we need to style our pill loader by adding our CSS. This will give our pill loader an upgraded presentation. Create a CSS file with the name of styles.css and paste the given codes into your CSS file. Remember that you must create a file with the .css extension.
Let's break down the CSS code:
1. @import: This rule imports the Montserrat font from Google Fonts to be used in the document.
2. :root: This is a CSS pseudo-class that represents the root element of the document, usually <html>. Custom properties (CSS variables) are declared here. These properties define cubic bezier functions for easing animations and a color variable for the UI color theme, as well as the duration for the loader animation.
3. body: This rule sets the font family of the entire document to Montserrat, falling back to a sans-serif font if Montserrat is not available.
4. .absCenter: This class positions an element absolutely in the center of its containing element by setting its top and left properties to 50% and then translating it back by -50% of its own width and height.
5. .loaderPill: This class sets up the container for the loader animation and aligns its contents to the center.
6. .loaderPill-anim: This class sets the height of the loader animation.
7. .loaderPill-anim-bounce: This class applies the animation for the bouncing motion of the loader pill using the loaderPillBounce keyframes animation.
8. .loaderPill-anim-flop: This class applies the animation for the flopping motion of the loader pill using the loaderPillFlop keyframes animation.
9. .loaderPill-pill: This class styles the loader pill element. It sets its dimensions, border radius, border color, and background gradient.
10. .loaderPill-floor: This class styles the floor of the loader animation.
11. .loaderPill-floor-shadow: This class styles the shadow beneath the loader pill.
12. .loaderPill-text: This class styles the text within the loader pill. It sets its font-weight, color, and text transform.
13. @keyframes: These are animation keyframes defined for the loader animation. They specify the transformations and timing functions at various points of the animation.
- loaderPillBounce: This keyframe animation defines the bouncing motion of the loader pill by changing its translateY property at different percentages of the animation duration.
- loaderPillFlop: This keyframe animation defines the flopping motion of the loader pill by rotating it at different angles.
- loaderPillScale: This keyframe animation defines the scaling motion of the loader pill by changing its scale along the y-axis at different percentages of the animation duration.
