Making HTML5 More Approachable: Writing for the Web, Accessibility, and Cyberinfrastructure

The white paper below is my final assignment for Week 1, Digitization Fundamentals, as part of the Graduate Certificate in Digital Humanities at DHSI 2015.


Learning to write for the web with HTML5 can be a daunting task. The general procedure is for students to view the raw data of an HTML document, learn about the meanings of tags and the process of encoding, and then hopefully begin writing HTML. This approach, however, relies on other embedded factors and assumptions, such as high computer literacy and facility with web environments. Especially in the Humanities where these skills are not necessarily required, newcomers to HTML are often anxious and afraid to share their projects with others. Discussing the basics of cyberinfrastructure[1] can help students visualize how documents circulate on the Internet, and using visual materials instead of raw code can help lower the barriers to writing for the web.

Defining HTML5

HTML5 consists of three parts, HTML (Hypertext Markup Language), CSS (Cascading Style Sheets, often referred to as CSS3, the third iteration), and Javascript (a programming language).[2] HTML is the markup language that adds semantic meaning to content. These HTML tags, such as <p>paragraph</p>, wrap-around and describe content with opening and closing angle brackets. The fifth version of HTML, or HTML5, contains new tags and markup for modern web development such as <video> and <audio>. CSS contains the aesthetic markers for altering the look and feel of webpages. CSS can be encoded within the HTML page, or as it most often is, referenced as a separate .css file or “style sheet.” The cascading nature of CSS refers to the ability of these style sheets to be hierarchical, where newer style sheets can overwrite previous ones without needing to remove or delete the latter. HTML and CSS are what the majority of people will work with when learning HTML5. Both HTML and CSS are methods of encoding content, not of programming or writing code. Javascript is the third portion of the HTML5 trio, and while essential for the web it can be perplexing for beginners. Javascript is the code-writing or programming portion of HTML5, and it can be tackled later on when a good foundation of HTML and CSS have been achieved.

Accessibility in Web environments

The word “accessible” can have multiple meanings when working with web environments. For many, the term accessibility relates to the openness of data on the web, making information clear and jargon-free, and also ensuring that links and important information are easy to find. However, accessibility also has a deeper meaning. Accessibility refers to the need to create digital environments that are inclusive, responsive, and universal in their design.[3] Web sites and digital projects must be created with all users in mind so that people with disabilities, whether physical, cognitive, or temporary, are not excluded from interaction.[4] Unfortunately, the process of learning HTML often skips past both usages of the word accessible, resulting in web environments that are complicated, and frustrating or impossible to use. Accessibility is often thought of after a project is completed, many times as a result of legal action.[5] Websites or other digital projects that have features of accessibility added to them after the fact can suffer from poor implementation and design, while also incurring additional costs for development. All digital projects, from the smallest personal webpage to the largest corporate website, should be designed from the very beginning with accessibility as a primary feature. The best place to start this process is with those just beginning to write for the web, whether in HTML5 or through other forms of web creation.

Text editors

A major stumbling block in the process of learning HTML5 is the text editor. Many new students learning HTML are unfamiliar with text editor programs, even if there’s already one installed on their computer. The text editor is generally less complicated to use than Word or other word-processing programs, but the unfamiliarity of the program can make students uneasy. An explanation of how word-processing programs incorporate code and other markup behind the visible surface of the document can help students see the reason for text editors. Spending time on the installation and usage of the text editor, along with ensuring that .html and other file extensions open by default, can help reduce student frustration. Instructors should also use the same programs that students are using, especially when projecting their computer screen to the class. It can be disconcerting to see a highly modified text editor running on the projector, and using the command line should be avoided for the sake of clarity as well. Students approaching HTML5 or programming for the first time can feel overwhelmed when watching an expert deftly maneuver through the command line interface with custom keystroke settings and other time-saving shortcuts.

Working from the outside-in

HTML is a method of encoding text with semantic meaning for the web. It’s common for instructors to begin with “lorem ipsum” text, and there are some entertaining lorem ipsum generators on the web, such as https://baconipsum.com and http://www.cupcakeipsum.com These lorem ipsum generators can add a splash of fun, but they are also another layer of abstraction for new students to navigate through. Instead of working with placeholder text, it would be best to work with materials that are familiar to the student, perhaps their own writing or text from a favorite book, poem, or website. The idea here is to help the student maintain a sense of control over the process and reduce anxiety. By using content that’s familiar, students will have a mental image for how the information should be structured and presented. Using as many familiar points of contact and reference as possible can help students overcome some of the initial fear, and work toward questions of design and presentation. A discussion using visual materials and avoiding raw code can help students see the logic behind HTML. A printed page from a simple website could be used for students to write on, where they might draw arrows pointing to different sections of the page and their corresponding HTML tags and elements.

Hierarchies and structure

Along with using familiar content for teaching HTML, a good overview of the hierarchies and structures of a webpage can be helpful.[6] Building accessibility into a webpage begins with the general layout and order of content. One of the most important aspects is to review how headings operate in a hierarchical structure, but paragraphs and other tags do not. The header tags of <h1>, <h2>,<h3>, and so on, can be quite confusing to new students, in part because of the changing font size associated with the tag. Students often choose a header tag because it changes the visual design, not because it presents information in a logical order. Screen readers and other assistive devices rely on header tags to move through web documents, and this hierarchical order is essential for navigation and meaning. Beginning with a discussion of header and paragraph tags, and how they’re used for semantic rather than aesthetic purposes, is a great place to discuss accessibility and good web design.

Writing for humans, and machines too

Once students have some content on their webpage, they inevitably look toward styling, which then leads to CSS or cascading style sheets.[7] Inline styling, or adding CSS markup within the HTML document, is often the first step. However, CSS markup is usually referenced in another file, referred to by a link in the head of the .html document. Inline styling is an older and more simple styling practice, and if separate style sheets were never used students would still be able to construct a basic webpage with some design features. Yet, there’s an opportunity with CSS files to show students how documents on the web can hyperlink to one another behind the scenes. Even though the links or referenced files in the head portion of the .html file are not visible to the user of the webpage, this information is essential for interoperability on the web. The head portion of the HTML document is important because it’s meant for computers to read, not people. Constructing documents in HTML5 is a process of writing for multiple audiences, including machines, and discussion about this can help students visualize how information moves through the Internet.

The basic workflow

Once the discussion of writing for machines is complete, moving toward a workflow that includes a referenced CSS style sheet can help put theory into practice. Generally, students will work locally on their own computers, and this can result in a lack of understanding about how documents are made visible on the web. There’s nothing inherently wrong with working locally, but without discussing the storage and retrieval of documents over the Internet students will be unable to put their new skills into practice. Online server space is needed for this portion of the class, and availability will depend on institutional resources. Even if there are no resources available, a discussion of the process is essential for students, as this will help them more fully understand what “working locally” means. This process of learning HTML and CSS, locally or otherwise, will require two separate programs to be open (the text editor and a browser), and three separate windows (.html file, .css file, and the browser window). If students can see how these three components relate to one another, they are more likely to understand how documents are stored, retrieved, and revised on the web. A more advanced discussion about FTP (File Transfer Protocol) programs, and discussing the need for SFTP (SSH or Secure Shell FTP), document permission settings, and online security would be wonderful if time allows.


Writing for the web in HTML5 can be complicated to learn, but focusing on visual methods and having directed class discussions can increase student understanding. With HTML and CSS, students can construct static webpages and share information more easily across software platforms and hardware devices. By avoiding proprietary or closed formats and programs, such as Word and .pdf files, students will be engaging in the 5 Star Open Data plan.[8] Most important for 5 Star Open Data is getting the materials online, and a basic understanding of HTML and CSS empowers students to contribute to the Internet in meaningful ways. With their new HTML5 skills, students will be able to interact more fully with programs that they may already be using, such as an LMS (Learning Management System, like Blackboard or Canvas) or a CMS (Content Management System, such as WordPress or Drupal). With accessibility as a primary feature from the very beginning, students will be creating documents that are easier for people to interact with, and by using the logics inherent in well-structured data they will be making the materials easier for machines to read as well. Learning the basics of HTML5 is an opportunity to publish materials online, as well as an occasion to learn about the fundamentals of cyberinfrastructure and digital literacy.
