On the surface, the new HTML5 specification is a huge change from the original HTML5 spec.
HTML5 is much more modular, which means you can easily change the layout and codebase of your webpages without breaking any of your existing web applications.
However, the specification also introduces a lot of new things that you won’t see in the old version of the specification.
There’s a whole new element to HTML5 that you don’t see when you use a previous version of HTML.
This is called a “polyfill”, and it is the biggest change to the HTML standard in the history of the web.
Let’s take a closer look at how it works.
What’s the new polyfill?
The new HTML spec introduced a new element called a polyfill.
Polyfills are essentially HTML elements that allow the browser to render certain parts of your webpage that aren’t already rendered by the server.
For example, you could render the header of your website with a polyfilled header tag.
This allows you to include a header that’s not already present on your website.
This new polyfilling element is called the “element container”.
In HTML5, an element container is basically a container that contains the content of the document.
An element container doesn’t have a root element, so the content inside it is contained in its own container.
You can think of it as a virtual container with a title and a content field.
The new element container element is named the “header” element.
So what exactly is the “content” field inside the header element?
The content field in a header element is the name of the page that contains that header element.
The content field is a string that identifies the page, like “
If you’ve used a traditional HTML header, you might find it hard to tell what’s going on inside of that header.
For instance, if you use HTML’s traditional
, you’d expect a
to be present on that page, but that’s just not the case.
The standard defines that the “h1” and “h2” elements should be treated as part of the header, but this is not true for all of the traditional HTML elements.
In other words, there are certain things that are not part of a header, like the text field in the
This means that if you have a
<a href="" on the page's body, the <a href="#" on its title is treated as an that’s in the header. That’s because there’s no content attribute on a element, and there’s only one at the top of a page, so no one can see the
