What is the issue causing a thin line to appear over some of the images on the page when resizing the browser window in Webflow?

When resizing the browser window in Webflow, a thin line may appear over some of the images on the page. This issue is typically caused by a few factors:

  1. Borders: Check if any borders have been applied to the images using the Webflow Designer. If a border is added to an image and its width is set to a value greater than 0, it may create a thin line around the image when resized.

  2. Image Scaling: Ensure that the images have been properly scaled to fit the containers they are placed in. If an image is scaled up beyond its original dimensions, it may result in pixelation or artifacts around the edges, appearing as a thin line.

  3. Image Compression: If the images are compressed using lossy compression methods (such as JPEG), it can lead to artifacts around the edges, especially when the image is resized. Consider using lossless image formats like PNG or optimizing image compression to minimize this issue.

  4. Pixel Density: High pixel density screens (such as Retina displays) may exacerbate this issue. It's important to use images with higher pixel densities to ensure crisp display on these devices. Make sure you are using images with appropriate resolutions to avoid the appearance of thin lines.

To mitigate the thin line issue when resizing the browser window, follow these steps:

  1. Remove any unnecessary borders from the images or reduce their width to 0.
  2. Ensure the images are properly scaled to fit the containers they are placed in, avoiding excessive scaling.
  3. Optimize image compression to reduce artifacts when resizing.
  4. Use images with higher pixel densities for devices with high pixel density screens.

By addressing these factors, you should eliminate the appearance of thin lines over the images when resizing the browser window in Webflow.
