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.

The purpose of the profound changes to the language was to standardize the many new ways in which developers were using it, as well as to encourage a single set of best practices with regards to web development. Most of the individual changes are a result of larger objectives in the design of the language.
These objectives primarily include:. If you want to get an intuitive sense of HTML5, it is best to understand how these objectives affected the development of the language. Semantic markup means markup which has meaning , rather than markup which simply looks a certain way. That semantic meaning would be lost if we just made the text bold and large without using the appropriate tag. HTML has always had a little bit of semantic markup available to it: heading tags , the link rel attribute , and document metadata.
In HTML, there are a host of new semantic elements intended to indicate the basic structure of a page:. These help search engines and other services to easily find information on a page, for display in other contexts. At the same time, existing inline elements which produce various effects like bold , italic , and underline have been refined or redefined to imply specific semantic meaning.
Along with strongly encouraging semantic meaningful markup, the HTML5 specification strongly discourages non-meaningful markup — markup intended only to tell the browser how to display things. This includes things like:. Most of the HTML features that allowed for these sorts of things have been completely deprecated. The few that are still officially supported come with warnings that they are usually not recommended practices. This variety alone should be enough to encourage semantic and responsive design practices.
Blind and visually impaired persons browse the web also, and they use a variety of assistive technologies to do so. No one sat down at the beginning of the internet and figured what types of things belong to each language. They each evolved in parallel to each other, often overlapping in functionality and scope. Besides the practical considerations enumerated above, there has also been a focus on defining the nature and purpose of these languages, and limiting them or expanding them so that they do what is in their nature to do:.
Remembering this can help one determine which language to use, especially in cases where it is possible to do something in more than one way. For example, if you want to change the color of something, your very first thought should be to use CSS. On the other hand, if you want to change the color of something in response to a user input , you probably want to use JavaScript.
As bandwidth and internet speed have increased, we have moved more and more toward using the internet as a media platform. HTML was originally created for hyper- text documents, with perhaps a few images, not rich media pages with audio and video.
When people first started adding these types of experiences to web pages, they required users to add special plugins to their browsers.
