HTML is a markup language that’s used to create web pages. It’s usually combined with CSS and JavaScript for dynamic functionality.

HTML can contain special components, known as tags, that label pieces of content like headings, paragraphs, images, links, tables, and lists. It’s important to understand the syntax of HTML so that your documents display correctly in a browser.

Scripting

Scripting is the process of adding functionality to a program, or making it “do something.” It’s often used for automating processes and creating dynamic experiences.

Unlike coding languages, scripts are short and run without the use of a compiler, so they’re generally faster. They’re also more portable, as they can be executed on a remote server or in the browser of the site visitor.

Scripting languages are easier to learn than programming languages, so they’re an ideal option for people looking to build websites or apps quickly. Some of the most popular and easy-to-learn scripting languages include JavaScript and PHP.

Variables

Variables are a part of the computer programming language that stores data. They can be used to store specific values, like a text color or a font size, and are also able to update dynamically using JavaScript.

In HTML, the var> tag is used to define variables for programming or mathematical expressions, and they are normally displayed in italics. This tag also supports all global and event attributes in HTML.

CSS variables, also called CSS custom properties, are a type of variable that stores and uses custom values in the CSS style sheet. They are a popular choice among web developers because they allow for reusability and easier maintenance of styles in a document.

Objects

If you’re looking to create a website, HTML is easier than C++ or Java. This is because HTML doesn’t require a lot of programming basics, just the requisite tags.

You can also use the object> tag to embed external resources such as videos, audios, images, PDF documents, and Flash. These are often accompanied by a param> tag that defines the various parameters to be passed to the embedded plugins.

Objects are the foundation of C++ and provide data abstraction, encapsulation, and inheritance to help minimize code size. They’re also a key element of video games, where high performance is imperative.

Classes

Classes are groups of HTML elements that have common styling. They’re similar to a real-life class — a group of students who share a certain set of interests, ages, area codes, or life goals.

In CSS, you can style an entire class of elements by using a class selector. You can also use class selectors in JavaScript via the Document Object Model (“DOM”) to manipulate an HTML element by its class.

There are three different types of selectors in CSS: class, attribute, and pseudo-class. Each type has equal specificity, but the one appearing latest in a stylesheet will override the other two.

Interfaces

C++ is a programming language that is used in a wide variety of different applications. This includes game development, software engineering, data structures, developing browsers and operating systems.

HTML is a markup language, which is used in combination with CSS and JavaScript to style websites. This is an extremely easy programming language to learn, and it is highly recommended that beginners get their hands on HTML first before moving on to other more advanced languages.

Using interfaces allows you to define a contract (agreement or blueprint) between your application and other objects, which defines what methods, properties and events are exposed by the object. This can help your applications run more smoothly, as well as making them much cleaner and more maintainable. It also makes code reuse easier.
