How can I create a portfolio in Webflow where users can click on an image within a project template page to view a larger version? Additionally, how can I apply a dark shadow to the entire screen when the image is clicked, focusing only on the image?

To create a portfolio in Webflow with the ability to view larger images when clicked, you can follow these steps:

Step 1: Set up your project template page
1. Create a new page or choose an existing page where you want to display your portfolio projects.
2. Set up your project template page by designing the layout and adding elements such as images, text, and buttons.
3. Make sure each project item is wrapped in a div block or a link block to serve as the clickable area for the images.

Step 2: Add a lightbox or modal to display larger images
1. Select the image element within your project template page.
2. In the right-side panel, click on "Add a Link" or "Link settings" to add a link to the image.
3. Choose the "Open modal" or "Open in lightbox" option from the link settings.
4. Customize the modal or lightbox settings according to your preferences, such as the size, transition effects, and close button design.
5. Inside the modal or lightbox content, add an image element and link it to the larger version of the image you want to display.

Step 3: Apply a dark shadow overlay when the image is clicked
1. Create a new section or div block that covers the entire screen and position it as fixed.
2. Style this section or div block to have a dark background color using the background settings.
3. Set the opacity of the section or div block to a desired value, such as 0.8.
4. Initially, set this section or div block to display none in the style settings to make it invisible.
5. Add an interaction to the image element within your project template page.
6. Choose the "Click" trigger and add a new action.
7. In the action settings, click on "Affect different element" and choose the section or div block you just created.
8. Set the action to show or display the section or div block with a desired animation or transition effect.

By following these steps, you can create a portfolio in Webflow where users can click on an image to view a larger version using a lightbox or modal, and also apply a dark shadow overlay to the entire screen when the image is clicked, focusing solely on the image itself.
