The World Wide Web relies on the communication between
web servers and browsers using the HTTP (Hyper Text Transfer Protocol) protocol. Web servers
transmit text in the form of HTML, CSS, and/or JavaScript to browsers, which interpret these
languages to render them into multimedia webpages.
HTML
(HyperText Markup Language) is the language used for
creating webpages and web applications. It describes the structure, appearance
and contents of webpages, using tag labels for paragraphs, headings, tables
and so on.
CSS
(Cascading Style Sheets) is a style sheet
language used for describing the presentation of a document written in a markup
language such as HTML. It is used to specify attributes such as font, colour,
alignment, margins, and more.
JavaScript is a dynamic
programming language that may be used in HTML
documents to provide dynamic interactivity on websites. For instance, developers
often use JavaScript to code the sequence of events that occur when a user
clicks a call-to-action button.
Higher-level programming languages such as PHP, Python, Java, and
C++ supported by Integrated Development Environments (IDEs) are extensively used
for website development. These languages offer more advanced functionalities, greater control,
and the ability to interact with databases and other software systems, making them ideal for
building complex websites and web applications.
