Encoding (Character Sets)

To display an HTML page correctly, a web browser must know which character set to use.
What is Character Encoding?
ASCII was the first character encoding standard (also called character set). ASCII defined 128 different alphanumeric characters that could be used on the internet: numbers (0-9), English letters (A-Z), and some special characters like ! $ + - ( ) @ .
ISO-8859-1 was the default character set for HTML 4. This character set supported 256 different character codes.
ANSI (Windows-1252) was the original Windows character set. ANSI is identical to ISO-8859-1, except that ANSI has 32 extra characters.
Because ANSI and ISO-8859-1 were so limited, HTML 4 also supported UTF-8.
UTF-8 (Unicode) covers almost all of the characters and symbols in the world.
The default character set for HTML5 is UTF-8.
The HTML charset Attribute
To display an HTML page correctly, a web browser must know the character set used in the page.


What is HTML Web Storage?

With web storage, web applications can store data locally within the user browser.
Before HTML5, application data had to be stored in cookies, included in every server request. Web storage is more secure, and large amounts of data can be stored locally, without affecting website performance.
Unlike cookies, the storage limit is far larger (at least 5MB) and information is never transferred to the server.
Web storage is per origin (per domain and protocol). All pages, from one origin, can store and access the same data. 0975868050

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.


Position

Use these shorthand utilities for quickly configuring the position of an element. 0975868050


Stretched link

Make any HTML element or Bootstrap component clickable by “stretching” a nested link via CSS.

The Viewport What is The Viewport?
The viewport is the user visible area of a web page.
The viewport varies with the device, and will be smaller on a mobile phone than on a computer screen.
Before tablets and mobile phones, web pages were designed only for computer screens, and it was common for web pages to have a static design and a fixed size.
Then, when we started surfing the internet using tablets and mobile phones, fixed size web pages were too large to fit the viewport.
To fix this, browsers on those devices scaled down the entire web page to fit the screen. This was not perfect!! But a quick fix.
