Content Delivery Network (CDN)

Definition

A Content Delivery Network (CDN), also known as a Content Distribution Network, is an expansive distributed system of servers positioned in numerous data centers across the Internet. The primary goal of a CDN is to provide web content to users as promptly, reliably, and efficiently as possible. It accomplishes this by serving the content from a location that is closest to the user.

Key Points:

• CDN collects and delivers static content such as images, videos, and JavaScript and CSS files.

• It stores the collected content on servers at various locations around the world.

• When a user requests a web page containing this static content, the CDN dynamically routes the request to the server that is geographically closest to the user.

• This method reduces latency, or delay, in delivering the content to the user, thus improving the overall performance of the website.

Animations

@keyframes Rule

The @keyframes rule in CSS is used to create animations. It specifies the animation sequence by defining keyframes (or stages) of the animation. The animation is created by gradually changing from one set of CSS styles to another.

Example:

@keyframes myanime {
    0% {
        background-color: aquamarine;
    }
    25% {
        background-color: yellow;
    }
    50% {
        background-color: blue;
    }
    100% {
        background-color: aquamarine;
    }
}

In the example above, the animation named myanime changes the background color at different stages (0%, 25%, 50%, and 100% of the animation sequence).

Grid Layout

Definition

The CSS Grid Layout is a two-dimensional layout system, optimized for responsive design. It allows developers to layout web pages in rows and columns, making complex responsive web design more straightforward and intuitive.

HTML Meta Viewport Tag

To make a web page look good and scale well on all devices (desktops, tablets, and phones), you should use the HTML <meta> viewport tag in your HTML code.

Example:

<meta name="viewport" content="width=device-width, initial-scale=1.0">

Including the viewport meta tag in your HTML code makes your web page more mobile-friendly by ensuring it scales and renders correctly on all device screens, particularly on devices with widths less than 600 pixels.
