โŒจ๏ธHTML Embed

The HTML Embed component enables the direct integration of custom HTML, CSS, and JavaScript code into your Webstudio project. With this component, you can extend the capabilities of your website, create interactive widgets, integrate external APIs, and implement personalized interactions.


How to use the HTML Embed component

The "HTML Embed" component can be found in Components > General, and you can place it on your canvas by dragging and dropping it or clicking it in the Components panel.


How to add custom code to an HTML Embed instance

You can add your custom HTML, CSS, or JavaScript code to the HTML Embed instance by selecting it and accessing its โ€œSettingsโ€.

Code

The "Code" section has a text area for adding your custom code. After you paste your code here, it will be rendered on the canvas. You can add anything to your site including custom widgets, third-party services, API integrations, animations, and interactive content.

Run Script on Canvas

The "Run Script on Canvas" toggle allows you to not only render the HTML embed directly on the canvas, but also execute scripts. It will look exactly the same way as when you publish the site.

Client Only

If your HTML embed is script-free and only includes items like SVG icons, CSS, or static HTML, you don't need this option.

For embeds with scripts that change HTML, like GSAP animations or sliders, activate the "Client Only" option. This prevents server-side rendering of the HTML. The embed, along with scripts, will render correctly once client-side JavaScript is loaded.

How to reuse your custom code across multiple web pages

You can reuse your custom code across your project by putting it inside a Slot instance.

  1. Add an HTML Embed component to your canvas and set it up with custom code of your choice.

  2. Add a Slot component to your canvas and place your HTML Embed instance inside it.

  3. Now, you can copy and paste this slot instance anywhere on your Webstudio project.

Please note that any updates you make inside your slot will update all other instances of that slot.

Avoid creating global variables

When using the tag, every variable you create is global by default, which can lead to unpredictable effects. Example:

<script>
    const a = 1;
</script>

In this example, we created a constant a and assigned the value 1 to it. However, because script tags by default use global scope, what really happened is that you created window.a = 1. What could go wrong? ๐Ÿ˜…

  1. If you navigate away and come back to the page, the script gets executed again and you will get a syntax error: "Identifier 'a' has already been declared". This is due to the fact that const can be declared only once. You could workaround this by using var or let instead.

  2. If your logic relies on an existing variable and you don't redefine it, it will use any random value that happens to be there at a given time.

Solution 1 - module

When using the module type, the script has its own scope, and the variables don't become global.

<script type="module">
    const a = 1;
</script>

Solution 2 - function scope

Use an Immediately Invoked Function Expression (IIFE) to create a function scope.

<script>
(() => {
    const a = 1;
})();
</script>
