HTML + CSS Tutorials

Description of HTML, CSS and JavaScript

HTML

HTML is a markup language used for describing web pages. It uses markup tags that describe the content of the document. It was designed for website creation. HTML is made up of a series of short codes typed into a text-file. Once the text has been saved as a html file it can be viewed through an internet browser. The browser then reads the file and translates the text into visible form. HTML stands for HyperText Markup Language. Hyper text is the method used to move around the web, clicking on special text called hyperlinks bring the user to the next page. 

JavaScript

JavaScript is the language for HTML, the web, computers, servers, tablets, smart phones, and more. It is a programming language used to make web pages interactive and runs on the visitors computer so that it doesn't require constant downloads from the creators website. It is also often used to create polls and quizzes. It is different to HTML in that HTML is a markup language designed for defining static web page content whereas JavaScript is a programming language designed for performing dynamic tasks. It is used for relatively simple functions e.g. popping up new windows or checking the information typed into a form to make sure it conforms to what the receiving database expects. 

CSS

CSS stands for cascading style sheets. Styles define how to display HTML elements. External style sheets can save a lot of work and are stored in CSS files. They define the layout of HTML documents allowing colours, margins, height and width to be changed along with many other elements. They were added to HTML to save a very large problem- HTML was created to define the content of the document and was never intended to contain tags for formatting it. Development of large websites where fonts and colour information were needed for every page became an expensive and long process. CSS was created to solve this meaning all the formatting could be removed from the HTML document and stored in a separate single CSS file.

Evidence of Codecademy Tutorial 

By doing these tutorials I learned the basics of HTML and CSS and the differences between them. HTML is the basic information for the website e.g. headers, text, tables and CSS is how this information is styled e.g. colours, borders, fonts. I learned the basic tags for making paragraphs, headers, lists, pictures, links and tables and how to style them using the CSS style sheets.
