Welcome to the science and technology section of Bella’s Fun World. Here you can learn about different programming languages that I know. You can also learn about new and innovative technology. Check back periodically to find new information about science and technology.

HTML stands for HyperText Markup Language. It’s a way of displaying information located on webpages in your web browser. One major thing to note is that HTML is not a programming language. It is in fact a Markup language. Programming languages use things called logic and conditions to control content. HTML does not have logic nor conditions but it is still important.

CSS is a design language that stands for Cascading Style Sheets. It is a design language that helps you style your web pages, changing aspects like the font, color, background style, border, and size. CSS works by setting rules for the elements in an HTML document. These rules define how the browser should present the content. If you want to style an HTML element, select it and indicate what you want to do with it.

JavaScript is one of the most popular scripting languages. Web developers often use it when developing their websites, applications, servers, and games. JavaScript is helpful to implement dynamic features for interactive elements. For example, you see the effects of JavaScript in animated graphics and slideshows. JavaScript improves the user experience by converting a static page – basic HTML and CSS page – into an interactive one. Along with HTML and CSS, the three languages form the foundation of web development.

Something to note is that JavaScript is different from Java. Java is often used for user-side development. It creates applications that run in a virtual browser, while JavaScript works on user-side scripts for interactive functions.

Python was first introduced in 1991 by Guido van Rossum. It is an object-oriented and high-level programming language widely used by software developers. Examples of platforms that use Python include Google, Facebook, Dropbox, and even Spotify.
