How can I limit the file size of the Webflow file upload field to less than 10MB using custom code such as JavaScript or jQuery?

To limit the file size of the Webflow file upload field to less than 10MB, you can achieve this by adding custom code using JavaScript or jQuery. Here's a step-by-step guide to accomplish this:

1. Add a file upload field to your Webflow form by dragging and dropping the File Upload element from the Add panel.

2. Give your file upload field a unique class name. You can do this by selecting the field and going to the Settings panel on the right-hand side. Under the "Class" section, add a class name like "custom-file-upload".

3. Go to the Page Settings of your Webflow project, and click on the "Custom Code" tab.

4. In the "Footer Code" section, add the following JavaScript code:

```javascript

```

5. Save your changes and publish your Webflow project.

Now, when a user tries to upload a file larger than 10MB in the file upload field, they will receive an alert message and the file input field will be reset.

The JavaScript code adds an event listener to the file input field. When a file is selected, it checks the file size in bytes and converts it to megabytes. If the file size exceeds 10MB, it displays an alert message and resets the file input field.

Note: This custom code solution uses JavaScript, but you can achieve the same functionality with jQuery as well. Simply write equivalent jQuery code for the same logic and include the jQuery library in your project.
