Webpage (r1) No None No 63 Worlds None

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 3.3.1.
  • Loads up lots of CSS - all the CSS used on the AB login pages. At the risk of conflict with user CSS. (Later APIs load up minimal 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" );


  • 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.
