Introducing trim, toUpperCase and toLowerCase Methods in Javascript | HTML + CSS + JS Course
HTML for Absolute Beginners:
While many guides on the internet attempt to teach HTML using a lot of mind-boggling theory, this tutorial will instead focus on giving you the practical skills to build your first site.
The aim is to show you ‘how’ to create your first web page without spending the entire tutorial focusing too much on the “why.”
By the end of this tutorial, you will have the know-how to create a basic website and we hope that this will inspire you to delve further into the world of HTML using our follow-on guides.
What is HTML?
Okay, so this is the only bit of mandatory theory. In order to begin to write HTML, it helps if you know what you are writing.
HTML is the language in which most websites are written. HTML is used to create pages and make them functional.
The code used to make them visually appealing is known as CSS and we shall focus on this in a later tutorial. For now, we will focus on teaching you how to build rather than design.
A Markup Language is a way that computers speak to each other to control how text is processed and presented. To do this HTML uses two things: tags and attributes.
CSS: Cascading Style Sheets:
Cascading Style Sheets (CSS) is a stylesheet language used to describe the presentation of a document written in HTML or XML (including XML dialects such as SVG, MathML or XHTML). CSS describes how elements should be rendered on screen, on paper, in speech, or on other media.
CSS is among the core languages of the open web and is standardized across Web browsers according to W3C specifications. Previously, the development of various parts of CSS specification was done synchronously, which allowed the versioning of the latest recommendations. You might have heard about CSS1, CSS2.1, or even CSS3. There will never be a CSS3 or a CSS4; rather, everything is now CSS without a version number.
JavaScript:
JavaScript (JS) is a lightweight, interpreted, or just-in-time compiled programming language with first-class functions. While it is most well-known as the scripting language for Web pages, many non-browser environments also use it, such as Node.js, Apache CouchDB and Adobe Acrobat. JavaScript is a prototype-based, multi-paradigm, single-threaded, dynamic language, supporting object-oriented, imperative, and declarative (e.g. functional programming) styles. Read more about JavaScript.
This section is dedicated to the JavaScript language itself, and not the parts that are specific to Web pages or other host environments. For information about APIs that are specific to Web pages, please see Web APIs and DOM.
The standards for JavaScript are the ECMAScript Language Specification (ECMA-262) and the ECMAScript Internationalization API specification (ECMA-402). As soon as one browser implements a feature, we try to document it. This means that cases where some proposals for new ECMAScript features have already been implemented in browsers, documentation and examples in MDN articles may use some of those new features. Most of the time, this happens between the stages 3 and 4, and is usually before the spec is officially published.
Do not confuse JavaScript with the Java programming language. Both "Java" and "JavaScript" are trademarks or registered trademarks of Oracle in the U.S. and other countries. However, the two programming languages have very different syntax, semantics, and use.
