When do we use html

This means that all the user-provided data is sent to the server all at once when the form is submitted, and the server can do whatever it wants with that data. When the server receives the form submission, it is like any other HTTP request. It does whatever it needs to do with the included data and issues a response back to the browser. Remember how a page load is a response? Same thing here. In a typical form submission, the response is a new page which the browser loads.

Typically the new page replaces the current one, but this can be overridden with the target attribute. There are a lot of form-related elements — different kinds of buttons, inputs, selectors for various types, feedback mechanisms… all sorts of things. In short: forms are complicated , maybe the most complicated aspect of HTML.

Every section has its own specific set of tags, which are dedicatedly rendered, keeping the head, title and body concepts in a loop. This is one of the most important uses of HTML, which is revolutionary.

This navigation is possible by utilizing the concept of Hypertext. It is basically a text which refers to other web pages or text , and when the user clicks on it, would navigate to referenced text or page. HTML is heavily used to embed the hyperlink within the web pages. A user can easily navigate the web pages and between websites as well, located on different servers. HTML5, with its set of standards and API, is being used to introduce some of the latest trends in the website creation business.

Like polyfill libraries, which are supported by old browsers equally well. A JavaScript library is available called Modernizr, which can detect features that let the developer dynamically load polyfill libraries as required. At the elementary level in applications of HTML, queries can be set to utilize the images, which are responsive in nature.

With the srcset attribute of img element in HTML and combining it with picture elements, a developer can fully control how the user will render an image. Now different types of an image with size variation can be loaded by using the img element. Rules can be easily set with the picture element; we can declare the img element with the default source, and then for every case, a source can be provided. These two strategies have their own standards and features. IndexDB, on the other hand, is a larger and better client-side data store.

Once data can be stored in the browser, the developer can think of a strategy to make the application work when a user is disconnected. HTML5 has its application cache mechanism, which would define how the browser manages the offline situation.

Application cache, responsible for offline ability, comprises different components, including API methods that create an update, read manifest file, and events. By using the certain property in HTML5, a developer can check if the application is online or not. In the manifest file, resources that are available offline can also be specified.

As browsers implement new HTML5 standards, developers can simply add the tags to the tag, indicating required fields, text, data format, etc. HTML5 has come up with several new attributes to drive on-screen keyboards, validation, and other data-entry experiences so that end-user can have a better data entry. Every feature of APIs needs not to be implemented, but the most appropriate ones can be utilized while eliminating the rest of the features. HTML5 adds so many new abilities and tools, which was just an imagination in the past.

A large set of new APIs regarding file system, Geolocation , drag and drop, event handling, client-storage etc. A modern web application has asynchronous nature, which can be fostered using Websockets and Web workers like APIs.

Anyone who can grasp the basic concept is to a good start. Gone are the days when HTML was synonymous with the usage of a certain set of elements, tags, and their attributes. With HTML5 , a developer has a lot of potential good tools and APIs in their arsenal, which can make its contemporary technologies lag behind. Usage in HTML is wide-spread and has become more sophisticated than ever before.
