Clean and simple. It shows a srollable window in a body tag surrounded by html tag, with head , so it creates a new dom. Unless, the styling is included within the imported text.

Take a normal, dynamically created stylesheet:. The same concept holds true for the import document. Unless you append it's content to the DOM, it's a no-op. See scripting in imports. Imports block rendering of the main page. The reason the browser blocks rendering on stylesheets in the first place is to minimize FOUC. Imports behave similarly because they can contain stylsheets. To be completely asynchronous and not block the parser or rendering, use the async attribute:.

The reason async isn't the default for HTML Imports is because it requires developers to do more work. Synchronous by default means that HTML Imports that have custom element definitions inside of them are guaranteed to load and upgrade, in order.

In a completely async world, developers would have to manage that dance and upgrade timings themselves. Imports don't block parsing of the main page. Scripts inside imports are processed in order but don't block the importing page. This means you get defer-like behavior while maintaining proper script order.

That's because an import can have script inside that needs to be executed before the script in the main page. Depending on your app structure and use case, there are several ways to optimize async behavior. The techniques below mitigate blocking the main page rendering.

Move scripts as late in the game as possible Another option is to have the import add its own content. If the import author establishes a contract for the app developer to follow, the import can add itself to an area of the main page:. Note: This very last approach is least preferable. The parser doesn't start to work on the import content until late in the page. Imports from the same URL are retrieved and parsed once.

That means script in an import is only executed the first time the import is seen. An import link doesn't mean " include the content here". It means "parser, go off an fetch this document so I can use it later". While scripts execute at import time, stylesheets, markup, and other resources need to be added to the main page explicitly. While useful by themselves, this idea becomes extremely powerful in the world of Web Components. HTML Imports are a simple concept, but enable a number of interesting use cases for the platform.

Chunk scripts - before imports, a large-sized JS library would have its file wholly parsed in order to start running, which was slow. With imports, the library can start working as soon as chunk A is parsed. Less latency! Enables switching between debug and non-debug modes in an app, just by changing the import target itself.

The load method takes the URL to be loaded as the first parameter. It has two other parameters, data and callback function, which are optional. The parameter data is the data to be sent to the server while processing the request. The callback function will execute if the load method completes. For example, go to CDN and choose the minified option on the latest version of jQuery.

Afterward, copy the code and paste it into the index. Then, create a p tag and write the text This is from index.
