CSS-CSS tool for web styling.

Example

CSS allows you to customize font sizes, styles (italic, bold), families (serif, sans-serif), and colors. For example, `h1 { font-family: Arial; color: red; font-size: 24px; }` makes all `<h1>` elements use Arial, be red, and have a 24px font size.

Scenario

In web applications, a company may want their brand colors and fonts to be consistently applied to headings, paragraphs, and buttons. By defining a CSS rule for these elements, the look and feel of the text across the site becomes uniform, contributing to brand identity.

Example

CSS controls the box model, which includes padding, borders, and margins around elements. For example, `div { margin: 20px; padding: 10px; border: 1px solid black; }` creates space around and inside a `<div>` element, enhancing the overall layout.

Scenario

When designing a web page, it's important to create space between elements for readability. The box model lets you adjust the spacing around text, images, and other elements, ensuring the page looks well-organized and not cluttered.

Example

CSS provides ways to position elements on a page using properties like `position: absolute;`, `position: relative;`, and `float`. For example, `div { position: absolute; top: 50px; left: 100px; }` places the `<div>` at an exact position within its container.

Scenario

In a dashboard application, you may want specific sections (e.g., a sidebar or navigation bar) to remain fixed or appear at certain positions as users scroll. CSS positioning helps achieve this, ensuring important content remains visible or placed according to design specifications.

Example

CSS enables the use of media queries to create responsive layouts. For example, `@media (max-width: 600px) { body { background-color: lightblue; } }` applies styles when the screen width is less than 600px.

Scenario

In today's mobile-first world, ensuring that websites display properly across a variety of devices is crucial. With CSS, developers can adjust layouts and styles for different screen sizes, offering a seamless experience on desktops, tablets, and smartphones.

Example

CSS supports smooth transitions and animations using properties like `transition` and `animation`. For example, `button { transition: background-color 0.3s ease-in-out; }` creates a smooth color change when hovering over a button.

Scenario

E-commerce websites often use CSS animations to make interactions more engaging. For example, when users hover over product images or buttons, smooth color changes or animations can improve the user experience, making the site more dynamic and visually appealing.

Example

CSS offers layout models like Flexbox and Grid for creating advanced, responsive layouts. For example, using Flexbox, `display: flex; justify-content: center;` aligns elements in a flexible, responsive row or column.

Scenario

Modern web design often requires complex, multi-column layouts that adjust dynamically based on screen size. Flexbox and Grid provide powerful tools to create these layouts without relying on outdated float-based designs, ensuring flexibility and ease of alignment.
