How to use Custom HTML?
With Custom HTML, there are two modes available:
- When the HTML is simple, it is rendered in the page directly (body), without an iFrame, example HTML code:
<span>This is simple HTML</span><select style="background: red"> <option value="0">0</option> <option value="0">1</option></select>For this mode, you can use inline styling. You should not add any <body> or <html> tags as the content is already rendered inside a <body> tag. If you wish to style the elements, then you can use Custom CSS to create new classes which you can apply to the elements here.
iFrame in Custom HTML
For security, when the HTML includes scripts or styles, it is rendered in an iFrame inside the page. For example, such code would be rendered inside an iFrame:
<style type="text/css"> .example-css { color: blue; }</style><div class="example-css"> This is HTML that will get encapsulated in an iFrame <button onclick="submit()"></button></div><script> function submit() { console.log("Script tags cause HTML to get encapsulated in an iFrame"); }</script>When using an iFrame, no pre-existing CSS would load, including CSS from Custom CSS or any third party library. Apply your own CSS rules.
Resizing Dynamic iFrames
If your Custom HTML is getting embedded in an iFrame, and the iFrame dynamically adds elements to the body which causes the height to be limited and the scrollbars to show, then you can instruct the iFrame to resize by using:
window.postMessage('resize', '*');Use this function whenever you add elements to body dynamically.
