How can I resize lightbox images in Spark theme?

Topic summary

A user is experiencing an issue with the Spark theme where lightbox images are too large and overlapping thumbnail images. They’re seeking solutions to either:

  • Reduce the lightbox image size
  • Reposition thumbnails to the left
  • Implement both changes

A proposed CSS solution was offered involving:

Implementation steps:

  1. Navigate to Online Store → Theme → Edit code
  2. Locate the theme.css file
  3. Add custom CSS at the bottom of the file

CSS code snippet:

.lightbox__image .image__img {
  margin-top: 100px !important;
}

Note: The provided code appears to add top margin rather than directly resize images or reposition thumbnails. The user should test whether this resolves their specific overlap issue.
