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. CSS was created by the World Wide Web Consortium (W3C) to address the need for better web page styling and management. Part of the curriculum will focus on HTML and CSS, which are used for building web applications.

What Is HTML?

HTML stands for Hypertext 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. An HTML document is the foundational structure of a web page and is written in a markup language. HTML is one of several markup languages used in web development. It is made up of elements.

  • <!DOCTYPE html> represents the document type and helps the browser to display web pages. It is not case sensitive and a declaration for HTML5.
  • <head> contains the metadata about the HTML page. It specifies the page’s description within 60 characters or less.
  • <title> specifies a title for the HTML page and sets the page title as it appears in the browser.
  • <body> defines the document’s body and contents, including headings, paragraphs, images, hyperlinks, tables, and lists.
  • <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>.
  • <p> defines a paragraph. It specifies the contents of text within a paragraph.
  • <img> defines an image within the body element. Within the image element, attributes are defined including the source file, alternative text, width, and height.
  • <ol> is used to create ordered lists (1, 2, 3, etc.).
  • <ul> is used to create unordered lists using bullet points.
  • <a> defines a hyperlink. It specifies where the browser should be 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. Attributes are also important in CSS, such as the style attribute, which allows you to apply inline CSS directly to an HTML element and can override styles from <style> tags or external stylesheets due to their higher specificity.

What Are the Advantages of HTML?

There are many advantages to using HTML to create web pages.

  • 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.
  • Separating style (CSS) from structure in HTML documents improves maintainability, reduces complexity, and enables responsive design across different devices.

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 enables styling of web pages by allowing web developers to write style definitions in separate CSS files, which helps maintain consistency and makes it easier to update styles across a site.

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. Common CSS properties include font family, font size, background color, and text align, which control how text and elements are displayed on the page. CSS also allows for different styles to be applied for different devices and screen sizes, making web pages responsive and adaptable to various display contexts.

What Are the Features of CSS?

CSS helps separate the design from the content to make the web page readable, flexible, and accessible. By separating content from presentation, CSS enhances accessibility for users with disabilities, allowing assistive technologies to interpret content more effectively and enabling content to adapt to different devices, user preferences, and special needs.

Additionally, browser support is required, as different web browsers may render CSS in varying ways, so web developers must consider compatibility to ensure consistent user experiences. New CSS modules and standards introduce additional functionality, but their adoption often depends on the level of browser support.

Here are some of the elements:

  • Internal CSS is 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. When using layout techniques like floats, floated elements interact with other elements on the page, causing surrounding blocks or inline elements to flow around them unless cleared.

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 web page 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.
