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.


HTML Versus XHTML

XHTML is a stricter, more XML-based version of HTML.
What is XHTML?
XHTML stands for EXtensible HyperText Markup Language
XHTML is a stricter, more XML-based version of HTML
XHTML is HTML defined as an XML application
XHTML is supported by all major browsers
Why XHTML?
XML is a markup language where all documents must be marked up correctly (be "well-formed").
XHTML was developed to make HTML more extensible and flexible to work with other data formats (such as XML). In addition, browsers ignore errors in HTML pages, and try to display the website even if it has some errors in the markup. So XHTML comes with a much stricter error handling 0976117671

Components and Props

Components let you split the UI into independent, reusable pieces, and think about each piece in isolation. This page provides an introduction to the idea of components. You can find a detailed component API reference here.
Conceptually, components are like JavaScript functions. They accept arbitrary inputs (called “props”) and return React elements describing what should appear on the screen.

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.
