What Is HTML and CSS?

Are you considering becoming a web application designer or developer? If so, the good news is that you will learn about the programming languages you need to know to start this career with the help of Hunter Business School’s Web Application Design and Development Program. Part of the curriculum will focus on HTML and CSS. So, what are HTML and CSS?

What is HTML?

HTML stands for Hyper Text Markup Language and is used to create web pages. HTML describes the structure of a web page and tells the browser how to display the content. It is made up of elements. Some HTML elements include:

Document Type Declaration

<1DOCTYPE html> represents the document type and helps the browser to display web pages. It is not case sensitive and a declaration for HTML5.

Head Element

<head></head> contains the meta-information about the HTML page; specifies the page’s description within 60 characters or less.

Title Element

<title></title> specifies a title for the HTML page and sets the page title as it appears in the browser.

Body Element

<body></body> defines the document’s body and contents, including headings, paragraphs, images, hyperlinks, tables, and lists.

Heading Element

<h1></h1> defines a large heading; these elements specify whether a certain part of the content is a heading or subheading and highlight the importance of the header within the HTML code. The heading elements range from <h1> to <h6>

Paragraph Element

<p></p> defines a paragraph; it specifies the contents of text within a paragraph.

Image Element

<img></img> defines an image within the body element. Within the image element attributes are defined including the source file, alternative text, width and height.

List Element

<ol></ol> ordered lists (1, 2, 3, etc) <ul></ul> unordered lists using bullet points

Link Element

<a href=”https://hunterbusinessschool.edu/”>https://hunterbusinessschool.edu/</a> defines a hyperlink; it specifies where the browser should when clicked upon.

What are HTML Attributes?

HTML attributes provide additional information for HTML elements. They are always specified in the start tag and usually come in pairs.

What are the Advantages of HTML?

There are many advantages to using HTML to create web pages. They include:

  • HTML is an agnostic operating system that works on Android, iOS, and Linux.
  • HTML is visually represented as a tree structure with parent and child elements.
  • HTML can be used in most browsers, including Microsoft Edge, Firefox, and Google Chrome.
  • It is easy to add content into HTML, like images, hyperlinks, and videos.

What is CSS?

CSS stands for cascading style sheets. They describe how an HTML element will display and control the layout of multiple web pages. CSS is used to define styles for a web page. CSS Syntax defines rules by specifying groups of styles for a web page to apply to an element or group of elements. For example, CSS syntax can define all <h1> tags as a specific color and size.

What are the Features of CSS?

CSS helps separate the design from the content to make the web page readable, flexible, and accessible. Some of the elements include:

Internal CSS – used as a style tag within the head tag

External CSS – adds an external CSS file in the head tag of the HTML file.

Inline CSS – defines properties for a single tag.

What Do You Use HTML and CSS For?

HTML and CSS are scripting languages used to create a web page or application. HTML provides the structure, and CSS controls the style. If we compare them to the human body, HTML is the bones, and CSS is the skin that covers the bones.

HTML helps create the primary content of a webpage and gives it structure. The process starts by writing words and then adding elements to those words. The web browser reads the elements and understands the hierarchy of the content.

CSS helps style HTML to improve the presentation and modify the design of web pages. HTML can incorporate CSS, but CSS cannot contain HTML.

What are Additional Programming Languages a Web Application Developer May Use?

Many programming languages help web application developers. They include:

Java – an object-oriented programming language that uses classes, objects, attributes and methods to code mobile applications and server-side technologies.

Ruby – an open-source programming language that focuses on simplicity and productivity. It is a highly portable general-purpose language that can be used to build desktop applications or automation tools.

Python – an interpreted, object-oriented, high-level programming language with dynamic semantics. It is used to build websites, automate tasks, and analyze data.

SQL – structured query language (SQL) is a standard database creation and manipulation language.

PERL – a highly capable, feature-rich programming language with many years of development. It is used for system administration, networking, and applications that involve user interfaces.

JavaScript – a cross-platform, object-oriented scripting language that allows a web application developer to create dynamically updating content, control multimedia, and animate images.

C# – an object-oriented, component-oriented programming language. It is a natural language to create and use software components.

C/C++ – C is a procedural programming language that does not support classes and objects. C++, on the other hand, is an extension of C programming with object-oriented programming support. C++ is the best language for creating large-scale applications.
