Is it possible to display the post summary under the featured post, but cut it off after the second line of text and end with "..." in Webflow? Also, can the summary still be limited to two lines of text even when the browser size shrinks?

Yes, it is possible to display the post summary under the featured post and limit it to two lines of text, ending with "..." in Webflow. Here are the steps to achieve this:

1. Create a Collection List: Start by creating a Collection List that will contain your blog posts. Make sure you have a Text field in your Collection to store the post summary.

2. Design your Featured Post: In your Webflow Designer, design the featured post section as per your requirements.

3. Add a Paragraph element for the summary: Inside your Collection List, add a Paragraph element to display the post summary. Set its class to something like "post-summary" for easier styling.

4. Apply text truncation with ellipsis: In the Style panel, go to the Typography section and set the "post-summary" class to have a maximum height of two lines. You can achieve this using the line-clamp property in CSS. Add the following custom CSS code to your page or site-wide CSS:
   ```
   .post-summary {
   display: -webkit-box;
   -webkit-line-clamp: 2;
   -webkit-box-orient: vertical;
   overflow: hidden;
   text-overflow: ellipsis;
   }
   ```

   This code will limit the paragraph to two lines and add an ellipsis at the end when the content exceeds the available space.

5. Responsive design: By default, limiting the text to two lines using line-clamp will still keep the text height the same when the browser size shrinks. However, if you want to adjust the summary to dynamically change to two lines on smaller screens, you can use CSS media queries. Here's an example:
   ```
   @media only screen and (max-width: 768px) {
   .post-summary {
   -webkit-line-clamp: 4;
   }
   }
   ```

   In this example, the summary will be limited to 4 lines on screens smaller than 768px, which will ensure that it's always displayed with two lines on smaller devices.

6. Bind the summary text: Finally, go back to your Collection List and bind the summary field to the Paragraph element you've added. This will automatically populate the summary for each blog post from your Collection.

By following these steps, you can display the post summary under the featured post in Webflow, limit it to two lines with an ellipsis, and adjust it to two lines even on smaller screens when the browser size shrinks.
