What is Multimedia?

Multimedia comes in many different formats. It can be almost anything you can hear or see, like images, music, sound, videos, records, films, animations, and more.
Web pages often contain multimedia elements of different types and formats.
Browser Support
The first web browsers had support for text only, limited to a single font in a single color.
Later came browsers with support for colors, fonts, images, and multimedia!
Multimedia Formats
Multimedia elements (like audio or video) are stored in media files.
The most common way to discover the type of a file, is to look at the file extension.
Multimedia files have formats and different extensions like: .wav, .mp3, .mp4, .mpg, .wmv, and .avi.
Common Video Formats
Videoformats There are many video formats out there.
The MP4, WebM, and Ogg formats are supported by HTML.
The MP4 format is recommended by YouTube.


Grid Container

To make an HTML element behave as a grid container, you have to set the display property to grid or inline-grid.
Grid containers consist of grid items, placed inside columns and rows. 0620228524


Cards

A card is a flexible and extensible content container. It includes options for headers and footers, a wide variety of content, contextual background colors, and powerful display options. If you’re familiar with Bootstrap 3, cards replace our old panels, wells, and thumbnails. Similar functionality to those components is available as modifier classes for cards.

Lifting State Up

Often, several components need to reflect the same changing data. We recommend lifting the shared state up to their closest common ancestor. Let’s see how this works in action.

JSX Consider this variable declaration:
This funny tag syntax is neither a string nor HTML.
It is called JSX, and it is a syntax extension to JavaScript. We recommend using it with React to describe what the UI should look like. JSX may remind you of a template language, but it comes with the full power of JavaScript.
JSX produces React “elements”. We will explore rendering them to the DOM in the next section. Below, you can find the basics of JSX necessary to get you started.
