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.

HTML Video

How it Works
The controls attribute adds video controls, like play, pause, and volume.
It is a good idea to always include width and height attributes. If height and width are not set, the page might flicker while the video loads.
The source element allows you to specify alternative video files which the browser may choose from. The browser will use the first recognized format.
The text between the video tags will only be displayed in browsers that do not support the video element.


Navs

Navigation available in Bootstrap share general markup and styles, from the base .nav class to the active and disabled states. Swap modifier classes to switch between each style.
The base .nav component is built with flexbox and provide a strong foundation for building all types of navigation components. It includes some style overrides (for working with lists), some link padding for larger hit areas, and basic disabled styling. 0680320745


Image replacement

Swap text for background images with the image replacement class.
