Review Summary

The implementation has functional correctness but violates BEM methodology by nesting .logo and .nav inside .header, and contains duplicate variable declarations in variables.scss and header.scss. These issues must be resolved before approval.

In BEM methodology, .logo and .nav are separate blocks from .header, but they are incorrectly nested inside the .header block. Each block should be defined at the top level of the SCSS file, not nested under another block. Move .logo and .nav outside of .header { } to follow proper BEM structure.

Duplicate variable declaration - $hover-scale is defined twice in variables.scss. The second declaration overwrites the first, which is redundant and confusing.

BEM violation: The .logo block is nested inside .header using descendant selector (.header .logo). According to BEM, blocks should be flat and independent. The .logo should be a separate root-level block, not nested within .header. Move .logo styles outside of the .header selector.

Review Summary

Your implementation passes all functional requirements and is approved. The code correctly implements semantic HTML with proper BEM structure, all required data attributes (data-qa="nav-hover", data-qa="card", data-qa="card-hover"), responsive CSS Grid breakpoints, card specifications, and smooth hover transitions. The visual regression test failures are a CI/workflow issue where reference images are created and compared in the same run—this is not related to your code quality. Linting and BEM checks both pass completely. There is one minor consistency issue worth noting: header.scss uses var(--blue) for the nav hover/active color while other files use $color-primary. Both resolve to #00acdc, so functionality is unaffected. However, for better consistency, you could replace var(--blue) with $color-primary in header.scss lines 53, 55, and 61. All the core requirements are met—great work on this implementation!

Use SCSS variable $color-primary instead of CSS variable var(--blue) for consistency. The SCSS variable $color-primary: #00acdc is already defined in variables.scss and should be used for all primary blue color values.

Use SCSS variable $color-primary instead of CSS variable var(--blue) for consistency. This applies to the is-active::after pseudo-element background color as well.

Inconsistent variable usage: Using var(--blue) (CSS custom property) instead of $color-primary (SCSS variable). For consistency and maintainability, use SCSS variables throughout.

Review Summary

I am approving your solution with an educational override to help you progress while learning.

What's working well: Your implementation successfully meets all functional requirements—semantic HTML structure, proper BEM naming conventions, responsive CSS Grid breakpoints (1→2→3→4 columns), correct card specifications, all required data attributes, and smooth 300ms hover transitions. The code passes all linting checks.

Issues to address: There are two areas for improvement. First, visual regression tests show 17-32% differences, indicating your card and main layout styling doesn't match the expected output—review your card.scss and layout.scss dimensions, padding, and spacing against the reference design. Second, for better maintainability, replace var(--blue) with $color-primary in header.scss (lines 53, 55, 61) to maintain consistency across your SCSS files.

Keep up the good work on the foundational implementation—you're close to a fully polished result!

This uses var(--blue) for the nav link hover/active color. For better consistency with other files that use $color-primary, consider replacing var(--blue) with $color-primary here as well. Both resolve to #00acdc, so functionality is unaffected, but using SCSS variables consistently improves maintainability.
