Can I upload a pre-existing CSS and HTML script in Webflow, or can I apply manual modifications to a Webflow script?

Yes, you can upload a pre-existing CSS and HTML script in Webflow. Here's how you can do it:

1. Go to your Webflow project and open the Designer.
2. Click on the "Code" tab in the top-left corner of the Designer.
3. In the "Custom Code" section, you'll see options to add custom CSS and custom HTML.
4. To upload a pre-existing CSS script, click on the "Add Custom Code" button under the "Custom CSS" section.
5. In the dialog box that opens, you can either paste your CSS code directly or upload a CSS file from your computer.
6. To add a pre-existing HTML script, click on the "Add Custom Code" button under the "Custom Head Code" section.
7. You can then paste your HTML code or upload an HTML file.
8. Once you've added your CSS and HTML code, click on the "Publish" button in the top-right corner to apply your changes.

It's also possible to apply manual modifications to Webflow's generated CSS and HTML code. Here's how you can do it:

1. In the Designer, click on an element you want to modify.
2. In the right sidebar, click on the "Settings" tab.
3. Under the "Styles" section, you'll find various properties that you can adjust.
4. You can add custom CSS styles by clicking on the "+" button next to the property you want to modify and then entering your CSS code in the dialog box.
5. To apply custom HTML modifications, you can use the "Embed" component to insert custom HTML code directly into your page.

Keep in mind that applying manual modifications to Webflow's generated code can have limitations and may affect the responsiveness and functionality of your site. It's recommended to use Webflow's built-in tools and features as much as possible to ensure optimal performance and compatibility.
