What Attributes Distinguish Quality HTML5 Developers From Others?
Like HTML, HTML5 is used to build interfaces for web applications, enabling developers to create intuitive layouts with a visual appearance that is professional and consistent with the company’s branding. However, a skilled HTML5 developer goes beyond aesthetics and leverages HTML5’s advanced features to enhance user experience, SEO ranking, and accessibility.
Common use cases and applications of HTML5
HTML5 developers differ from web developers: While web developers have a skill set that encompasses a broad range of knowledge and expertise, HTML5 developers specialize in implementing the features and capabilities introduced in the HTML5 specification. Not every company requires this advanced functionality, but teams that are building web applications that will feature rich interactivity, multimedia content, and dynamic graphics and animations will benefit from hiring HTML5 programmers.
HTML5 Feature
Business Advantage
Real-time Functionality
With the addition of WebSockets, HTML5 enables real-time communication, enabling developers to create applications like live chat, collaborative tools, and multiplayer games.
Offline Support
HTML5 provides features such as local storage and offline caching, allowing applications to function even without an internet connection.
Responsive Design for Mobile Websites and Apps
HTML5 gives developers the tools to build webpages that adapt seamlessly to different screen sizes and devices.
Embedded Multimedia Content
HTML5 provides native support for audio and video, enabling HTML5 developers to embed multimedia content into websites. This enables a wide variety of applications, from background videos on a landing page to browser-based games.
Interactive Graphics
HTML5 developers can add interactivity to graphics with WebGL, a JavaScript API, which allows the creation of interactive infographics and data visualizations, and browser-based games with complex 2D or 3D graphics.
HTML5 developers collaborate with stakeholders across a web app’s lifecycle. They work closely with UI/UX designers to translate wireframes into functional HTML5-based user interfaces. They also collaborate with back-end developers to implement front-end components that communicate with back-end logic and databases. When components are ready for testing, HTML5 developers work with quality assurance (QA) engineers to ensure that the web interface is bug free and compatible across different browsers and devices.
Core skills for HTML5 development
Just like previous versions of HTML, HTML5 uses tags to tell the browser how a webpage should be displayed. The HTML5 update also introduced semantic tags, which are used to describe the meaning of the content they contain. Understanding how to use tags to structure a webpage is the core skill of an HTML5 developer. They should also understand the principles of responsive design and know how to use HTML5 to create webpages that are compatible with all browsers, automatically scaling to the screen resolution of any device.
In addition, experienced HTML5 developers should be versed in both CSS3 and JavaScript. While HTML5 is used to structure and provide semantics to a webpage, CSS3—an evolution of the cascading style sheets (CSS) language—defines the webpage’s visual style. CSS3 is used to specify colors, fonts, layouts, and even complex animations. HTML5 developers should understand how to use CSS3 skills, such as media queries, transforms, flexbox, and grid, as well as transitions and animations, to make a website dynamic and visually appealing.
Along with a slick design and animation, modern websites are often interactive. JavaScript is a versatile scripting language that can be used to add interactivity to static content. JavaScript enables the HTML5 developer to respond to user actions, handle events, fetch data, and update page content without requiring a page reload. It is also tightly integrated into HTML5, with features like canvas, web storage, geolocation, and web workers, all accessed and controlled by JavaScript. If a candidate is building a dynamic webpage with features like sliders, form validation, and interactive maps, JavaScript is required knowledge.
What is the difference between HTML and HTML5? What skills are required for HTML5 development compared to other versions of HTML?
HTML and HTML5 share the same basic structure; both use tags to define the layout of a webpage. However, HTML5 represents a major upgrade from HTML, with a myriad of improvements and new features that enable developers to move beyond static webpages and build more dynamic web experiences. Key advancements include support for scalable vector graphics (SVG), native audio and video streaming, and drag-and-drop interactions. HTML5 also offers additional functionality such as local data storage, web workers, WebSockets for real-time communication, and WebGL, which enables hardware-accelerated graphics. HTML5 developers have a broader skill set, which includes not only previous versions of HTML, but also a deeper understanding of software development concepts, such as APIs, client-side storage, multimedia components, and dynamic rendering of graphics. Additionally, HTML5 developers should understand the concept of semantic elements and how they help organize a webpage and make it accessible.
How Can You Identify the Ideal HTML5 Developer for You?
There are several factors to consider when finding the right HTML5 developer. Because the project’s complexity, timeline, and budget all play an important role, the project’s requirements must first be defined. Consider the functionality of the website and the user experience you are trying to create. For an entertainment website, the objective might be a design that is animated and visually stunning, while for an e-commerce website, the priority might be ease-of-use for its customers. Answering these questions will help to define a project’s needs, as well as the skills that the HTML5 developer must have.
Assessing HTML5 developer experience levels
Once you have an idea of which skills the HTML5 developer needs to have, think about their experience level. Budget is a consideration, however, prioritizing skill level is often more important. Hiring a junior developer may be more cost efficient, but their lack of experience could cause delays on complex projects. Despite the higher initial cost, hiring a senior HTML5 developer can save you money in the long run, as the knowledge gained from their experience lets them develop more efficiently and deliver projects ahead of schedule and under budget.
Junior HTML5 developers have one to three years of experience, and are proficient in HTML5 and CSS3, with a basic understanding of related languages such as JavaScript. Junior developers can design and build webpages and interfaces, but may need the guidance of a more experienced developer when it comes to more complicated tasks, such as writing scripts to interact with back-end software or developing an animated user interface.
A mid-level HTML5 developer has three to five years of experience under their belt. They are proficient in HTML5, CSS3, and JavaScript, and have typically worked with libraries and frameworks like jQuery, React, and Angular. Mid-level HTML5 developers also understand and implement best practices for SEO and accessibility. They have a well-rounded skill set and have experience building and deploying functionality-rich web applications in a variety of environments.
With more than five years of experience, senior HTML5 developers are seasoned veterans with a proven track record of solving problems and delivering complex web applications. They’re proficient at using features like geolocation (for delivery or ridesharing apps), WebSockets (on editing tools or interactive games), and HTML5’s application cache (for offline apps). On top of having mastered the skill set of a mid-level HTML5 developer, they are confident in leading development teams and making decisions that can impact entire projects, from design and implementation to testing and deployment.
Complementary technology skills for HTML5 developers
Beyond having a strong foundation in HTML5, CSS3, and JavaScript, HTML5 developers of all experience levels benefit from a variety of complementary technology skills.
CSS frameworks: As mentioned, CSS and CSS3 are used to shape the visual presentation of a webpage. To accelerate development and ensure consistency, frameworks like Bootstrap and Materialize provide prebuilt styles and components.
Front-end frameworks: In addition to JavaScript, HTML5 developers can benefit from knowing how to use front-end frameworks and libraries, such as Angular, React, jQuery, or Vue.js, which provide prebuilt components and tools for making web-based user interfaces more dynamic and interactive. These frameworks make it easier to add functionality like form validation, routing, authentication, data visualization, and integration with back-end APIs.
Website development: Website development covers a wide range of skills, including design, front-end, back-end, database management, and deployment. HTML5 developers primarily work with the front end, structuring the webpage and developing the look, feel, and user experience. Some HTML5 developers may also have experience integrating the front- and back-end of web applications. HTML5 developers typically do not work directly with back-end code or databases, however, experienced candidates might bring with them a well-rounded skill set and knowledge in all aspects of web development.
User experience (UX) design: Candidates should have an understanding of design principles in order to build user-friendly websites. Even if there is a dedicated UI/UX designer, this knowledge helps HTML5 developers translate designs into functional websites.
Responsive design: Because they are viewed on so many different types of devices, webpages must automatically adapt to different screen sizes and devices. Understanding the principles behind responsive design helps HTML5 developers optimize webpages across all different platforms.
Accessibility and compliance: Candidates should be familiar with and follow accessibility standards, such as the standards provided by the Americans with Disabilities Act and the World Wide Web Consortium. Following best practices for accessibility can not only make a website easier to read, but is legally required in many jurisdictions.
Search engine optimization (SEO): Proper use of HTML5 tags can affect a website’s ranking in various search engines. Candidates should understand basic SEO principles and follow best practices when building a webpage.
Problem-solving skills: Whether optimizing front-end performance, fixing layout bugs, or enhancing user interfaces, being able to handle potential problems is a critical skill. Experienced candidates should be able to dissect problems and bugs methodically, coming up with efficient and effective solutions. Additionally, candidates should have experience with debugging tools like Chrome DevTools or Firebug, analyzing their outputs and logs to identify potential issues.
How to Write an HTML5 Developer Job Description for Your Project
In order to attract qualified candidates, a job description needs to be detailed and compelling.
Start with a summary of the project and how it impacts the company’s goals. Give an overview of the position and its key responsibilities. These may include tasks like designing user interface components, maintenance, optimizing performance, and ensuring cross-platform compatibility. Specify the technical skills involved, indicating any complementary skills other than HTML5 and CSS3. These can include front-end technologies like React and Angular or back-end technologies like .NET or PHP. Complementary skills can also include graphic design and UI/UX design, as well as SEO optimization. If the technical skills aren’t set in stone, divide the list into “must haves” and “nice to haves.” Highlight the level of experience you are looking for, whether it’s a junior, mid-level, or senior developer.
Give an overview of your company: its culture, values, and work environment. Finally, mention if the job is on-site, hybrid, or if you are hiring remote HTML5 developers. These details help candidates identify jobs that line up with their work preferences.
What Are the Most Important HTML5 Developer Interview Questions?
The interview process gives you a chance to get to know each of the candidates and assess their fit for the HTML5 developer position. Asking about previous projects will give candidates a chance to talk about their experience and allow you to follow up with technical questions. In addition to evaluating technical skills, make sure to ask questions that relate to the candidate’s soft skills, including communication, teamwork, and time management. It’s also a good idea to ask for a portfolio showing webpages that the candidate has built in the past.
The following example interview questions will give you insight into a candidate’s knowledge and experience with HTML5.
How do you create a responsive website using HTML5?
There are several approaches to creating a responsive website. Candidates should be able to name a few methods, including using media queries in CSS, flexible layouts, or the viewport meta tag. Images and media elements should also be set to scale proportionally with screen size by setting their maximum width to 100%. Additionally, CSS frameworks like Bootstrap offer prebuilt components for creating responsive webpages. Because webpages are viewed on so many different screen sizes and devices, knowing how to make them responsive is an essential skill that every HTML5 developer should have.
Describe your use of JavaScript in previous projects.
This conversation lets the candidate show off their knowledge and practical experience with JavaScript. Because JavaScript is tightly integrated with HTML5, it is an essential skill for any projects that require user interaction, animation, and effects, as well as client-side data processing and validation. It also opens the doors for more advanced features, like geolocation and camera access. Not all projects require expertise in JavaScript; however, a solid understanding is highly beneficial for all HTML5 developers.
What is the difference between semantic and non-semantic HTML5 elements?
Semantic elements like <header>, <article>, and <nav> describe the purpose of their content, while non-semantic elements like <div> and <span> only describe how they are presented. Semantic elements have the benefit of improved SEO and accessibility. All candidates should be familiar with semantic and non-semantic elements, as they are fundamental components of HTML5.
What is the canvas element in HTML5?
The <canvas> element is a feature of HTML5 that provides a blank rectangular area for rendering graphics and visual content dynamically. Drawing is done using JavaScript and the canvas API. By handling user input events like mouse clicks or screen taps, the canvas element can be used to create interactive content, such as data visualizations and games. Candidates who have worked with interactive graphics should have hands-on experience with the canvas tag in HTML5.
What is the difference between local storage and session storage?
The localStorage and sessionStorage objects are both used to store data on the user’s device. With session storage, the data is cleared when the browser tab or window is closed, while local storage data persists even after the browser is closed. They can be used to store various types of data, such as user preferences, form data, or authentication tokens. Because most web applications need to maintain state between pages, knowing how to use local and session storage is essential for an HTML5 developer.
How do you ensure that the websites you develop meet accessibility standards?
There are several strategies that HTML5 developers can incorporate so the webpages they design are accessible to all users. The use of semantic elements, accessible rich internet applications (ARIA) roles and attributes, and alternative text for images benefits screen readers and other assistive technologies. The color contrast between text and backgrounds should be enough so that the page is readable to users with low vision or color blindness. Additionally, candidates should be familiar with all applicable guidelines, such as web content accessibility guidelines (WCAG). Accessibility is a key concern in web development, and all candidates should be able to speak to their approach when building a website that is inclusive and usable by all users.
Why Do Companies Hire HTML5 Developers?
In order to create an online presence that stands out in the sea of webpages, many companies hire dedicated HTML5 developers. HTML5 is the backbone of building modern webpages and applications. Combined with CSS and JavaScript, HTML5 can be used to create dynamic websites that include features like multimedia applications, interactive data visualization, and real-time collaboration. It can even be used to develop browser-based video games. HTML5 is significantly more powerful than its predecessor and, with its additional features, is much more complex. It takes a talented HTML5 developer to harness this power in order to build websites that are visually stunning, interactive, and work flawlessly across all platforms.
The Popularity and Adoption of HTML5
Major websites and platforms have embraced HTML5, depending on it to deliver dynamic and interactive user interfaces. YouTube transitioned from using Flash to HTML5 as its default player to leverage browser-native video playback. Netflix also uses an HTML5 player to play videos in the browser. HTML5 is now the backbone of most websites. For businesses looking to deliver a rich user experience, HTML5 is the top choice.
