API: Webpage (r2)

This API is for Worlds with no canvas. That is, the World is a web page with regular HTML elements.

This site is mostly about uploading JS (not HTML) to make a World which normally "runs" on a canvas element on a page. This API is different to the other APIs. It allows you make a World with no canvas.

This API has the following features:

• It gives you a blank page, and you use JS to insert whatever HTML and CSS and data you want on the page.
• Your World can just document.write HTML and CSS into the body.
• The API sets a page title.
• There is no run header, so as not to interfere with your page layout.
• You reload and close the page like any other tab.
• Links on the page open in the same window (not in a new window like in the canvas APIs).
• Includes jQuery 3.6.0.
• Loads up minimal CSS that should not conflict with user CSS.

• The style of the blank page is a body with margin 0 and padding 0. You can change it using JS like this:

   
    $('body').css( "margin", "20px" );
    $('body').css( "padding", "20px" );
  

Screenshots:

• The screenshot does not assume there is a canvas. Instead it takes a screenshot of the HTML.
• It uses the html2canvas library to build a screenshot of your page using JS.
• The html2canvas library has some limitations and may not be able to accurately screenshot your page.
