How To: Build A Simple App In HTML 5

What is HTML and HTML 5?

Hyper Text Markup Language is referred to as HTML . Through the use of a markup language, it is used to build web pages. Hypertext establishes the connection between web sites. The text document within a tag that determines the structure of a web page is defined using markup language. The most recent and fifth version of HTML is HTML 5. Application programming interfaces (API) and the Document Object Model have both been made available, and document markup has been improved (DOM).

The most recent HTML version is HTML5. The phrase has two meanings. One is the new elements and attributes in the revised HTML language itself. The second is a broader collection of technologies that may be used with this new HTML version to create more sophisticated and potent websites and apps, such as a new video format.

To put it simply, HTML is a set of principles that instructs web browsers on how to parse code to display web pages. The fifth edition of this set, HTML5, enhances and updates website functionality while assisting web developers in creating more interactive and dynamic web content, such as websites and web applications.

What is the difference between HTML and HTML 5?

The primary markup language used on the World Wide Web is HTML. It was first intended to describe scientific texts semantically, but it has subsequently expanded to describe much more.

Today’s majority of online sites were created utilising HTML4. HTML4 still maintained its restrictions despite being significantly improved since the initial draught of HTML, which was developed in 1993. The biggest one was when web designers or developers sought to add features or material to their website that HTML didn’t support. In that situation, they would have to employ proprietary, non-standard technologies like Adobe Flash, which required users to set up plugins for their web browsers. Some people might still not be able to access that material or function even then. For instance, users of iPhones and iPads couldn’t because those gadgets don’t support Flash.

Cue, HTML5. These proprietary non-standard technologies were intended to be eliminated with HTML5 . With this updated version of HTML, you can build web apps that operate without an internet connection, support high-definition video and animations, and identify users geographically.

So, what’s new in HTML 5?

The?main goals of HTML5’s design are:

1) To make the code simpler for users and screen readers to read.

2) Reducing HTML, CSS, and JavaScript’s overlap with one another.

3) Encouraging responsiveness and uniformity in design across browsers.

4) Providing multimedia support without requiring Flash or other plugins.

Each of these goals served as the basis for the modifications in this new HTML version. Here, we’ll concentrate on seven of those modifications.

New Semantic Elements

Several new tags with semantic significance were added to HTML5. Among them are <section>, <header>, <footer>, <nav>, <mark>, <figure>, <aside>, <figcaption>, <data>, <time>, <output>, <progress>, <metre>, and <primary>. These facilitate the writing of cleaner code that distinguishes clearly between style and content, which is crucial for users of assistive devices like screen readers.

Inline SVG

Scalable vector graphics (SVGs) cannot be added to web pages using HTML4; instead, you must use Flash, Silverlight, or another technology. Using the <svg> tag, HTML5 allows you to easily add vector graphics to HTML texts. Using this new element, you may also draw text, circles, rectangles, and other vector-based routes and forms.

Form Features

Because HTML5 has more form choices, you can design more intelligent forms. HTML5 includes additional form input types in addition to the usual ones, such as datetime, datetime-local, date, month, week, time, number, range, email, and url. Thanks to the new placeholder attribute, which we’ll cover later, you can also include date pickers, sliders, validation, and placeholder text.

WebM Video Format

Prior to HTML5, browser plugins were required in order to incorporate audio and video content into web pages. HTML5 introduced the WebM video format in addition to the audio and video tags that rendered browser plugins unnecessary. This is a Google-created royalty-free video format that offers an excellent compression to quality ratio. This is supported by the majority of browsers and can be used with the video element.

Placeholder Attribute

The placeholder attribute debuted in HTML5. This works well with the input> element to provide users a brief tip to fill out passwords or other data entry areas. You could improve your forms by doing this. The fact that assistive technology cannot access this feature, however, should be noted.?

Server-sent Events

A web page automatically receiving updated data from a server is known as a server-sent event. With HTML4, this was possible, but the website would need to ask

HTML5 allows for server-sent, one-way events. In other words, a server continuously sends data to the browser. Consider how helpful it would be if your website provided access to Twitter feeds, news feeds, stock prices, and other information. In the previous version of HTML, server-sent events were supported, but the web page had to constantly request them.

Local Web Storage

Cookies are used in HTML’s previous version to store data locally. Thanks to a scripting API in HTML5, web storage is used in place of cookies. This enables you to store considerably more data locally, much like cookies.

Why do we choose HTML 5?

Over earlier HTML versions, HTML5 offers a wide range of advantages, some of which we’ve already briefly discussed. Let’s examine a few of the characteristics that make HTML5 unique in more detail.

It’s compatible across browsers.

Chrome, Firefox, Safari, Opera, iOS for Chrome and Safari, and Android browsers are all popular browsers that support HTML5. Even outdated and less used browsers like Internet Explorer are compatible with it. By using HTML5, you can be sure that users of your site will have a consistent experience regardless of the browser they use or whether they are using a mobile device or a desktop.

It enables offline browsing.

HTML5 enables the creation of offline applications. Browsers that support HTML5 offline apps (the vast majority) will download and cache the HTML, CSS, JavaScript, pictures, and other resources that comprise the application. The browser will then render the local copies when the user tries to access the web application without a network connection. That means you won’t have to worry about your site not loading if the user loses or isn’t connected to the internet.

It allows you to write cleaner code.

You can make code bases that are cleaner and more descriptive by using HTML5’s new semantic elements. Prior to HTML5, programmers had to make extensive use of generic components like divs and design them using CSS to make them seem as navigation menus or headers. The result? There were numerous divs and class names, which made the code more challenging to comprehend.

You can separate style from content with HTML5 since it enables you to write more semantically meaningful code.

It’s more accessible.

Additionally, you may design more accessible websites and apps with the help of HTML5’s new semantic features. Before the introduction of these components, a div with the class or ID name “header” could not be distinguished from a header by screen readers. With the addition of the header> tag and other semantic HTML5 tags, screen readers can now more easily analyse an HTML file and give users who rely on them a better experience.

What are the various HTML 5 Apps? Let’s check out some examples.

Native Apps?

Apps that are native can be downloaded via the Apple Store or Google Play Store. The native app differs from hybrid applications and web apps in that they are designed for a particular device.

For instance, iPhone apps are created using Objective C, but Android apps are created using Java. The benefit of using a native app is that they are the fastest and most dependable, providing a superior user experience.

Furthermore, native apps have access to the operating system’s tools like the camera, microphone, contacts, location, and more. However, the native application needs a lot of upkeep, therefore you need a greater budget for cross-platform support.

Web Apps?

The word itself implies that Web applications are usually webpages but have more of a mobile app feel to them. The online apps can function in a variety of browsers, including Safari and Google Chrome. JavaScript or HTML5 was used to create this app.

Building a web app would be the best and least expensive option if you are starting a business on a short budget because it doesn’t call for complex functionality or allow OS features. There are certain drawbacks despite the fact that it is inexpensive and within budget. The disadvantages of online apps include their slower speed, poor readability, and inaccessibility across all app stores. Additionally, customers won’t frequently see your site icon on the home screen, which will discourage them from using it.

Hybrid Apps?

The features of both web applications and native applications combine to create a hybrid application. The development of hybrid applications is quicker and simpler. The same as native apps, hybrid apps would be accessible through all store apps. Additionally, they can incorporate OS features like native programmers. Speaking of web apps, hybrid apps may be cross-browser and cross-web technology interoperable.?

The hybrid application demands little upkeep. The speed of the user’s browser ultimately determines hybrid app performance. It states unequivocally that hybrid apps will never be quicker than native apps. This app’s key advantage is that it can be developed on a single foundation, allowing you to add new features to many versions of your app. Native apps, on the other hand, must duplicate new functionality for each platform.
