jQuery is considered to be a lightweight, “write less, do more” form of coding. It’s purpose is to make it easier for JavaScript to interact with your website.

HTML or “HyperText Markup Language”, is a form of computer language that can be viewed by anyone connected to the Internet. HyperText is the method by which we traverse the web. By clicking on words that have hyperlinks that lead to other sites and locations. The “Hyper” is a reference to HTML’s non-linear functionality, meaning you don’t need to go in a specific order of links to get somewhere. Markup is referencing what the HTML tags do to the text they are attached to. They mark the text as a certain type (for example; bold). How does it work? HTML consists of a series of short codes typed into a text file by the coder, and this is known as tags. The text is then saved as the familiar html file, which can then be viewed in a browser (like Google Chrome). This browser reads the file and translates the text into a visible form and attempts to render the page as the coder intended.

JavaScript is another form of coding language that allows you to implement complex things on webpages. Javascript is behind the more animated and complex aspects of a website, for example timely content updates, interactive maps, animated 2D/3D graphics, scrolling video jukeboxes and more.

Javascript is a language that enables the user to create dynamically updating content, control multimedia, animate images, and anything else you can think of that involves interactives on a website. 
When it comes to the core Javascript capabilities, the most common features allow you to do the following:

When it comes to the core Javascript capabilities, the most common features allow you to do the following:

• Store useful values inside variables
• Operations on pieces of text (Strings)
• Running code in response to certain events occurring on a web page

CSS stands for Cascading Style Sheets, and is a simple design language intended to simplify the complexities of making web pages presentable.

CSS takes charge of the look and feel of a web page, controlling factors like the color of text, the style of fonts, the spacing between paragraphs, how columns are sized and laid out, what background images or colors are used, layout designs, variations in display for different devices and screen sizes as well as many other effects.

CSS provides powerful control over the presentation of HTML documents and is commonly combines with the markup languages of HTML or XHTML.

A list of the advantages of CSS:

• Time saver- You can write CSS once and then reuse the same sheet in multiple HTML pages. You can even define a style for each HTML element and apply it to as many web pages as you desire
• Page load times- Using CSS means you don’t need to write HTML tag attributes every time. Just create  a rule of a tag using CSS and apply it to all the occurrences of that tag. So less code means faster download times and happier customers
• Ease of maintenance- Global changes are easy to do by simply changing the style, and watch as all the web pages automatically update
• Superiority over HTML in most instances- CSS boasts a wider array of attributes than HTML, so you can have a page that is visually stronger than that created by HTML
• Multiple Device Compatibility- Style sheets enable content to be optimized for more than one type of device. By using the same HTML document, different versions of a website can be presented for handheld devices such as PDAs and cell phones or for printing
• New rising standards- HTML attributes are generally being deprecated and CSS is taking over as the recommended. This means CSS will be necessary for most all web pages for compatibility sake 
• Offline Browsing-  CSS has the ability to store web applications locally with the help of offline catch. With the help of this functionality we can view offline websites and ensure faster loading and better overall performance of websites when online
• Platform independence- The Script offer consistent to platform independence and has the capabilities to support latest browsers as well
