Review Summary

This implementation has several critical issues that violate task requirements and must be fixed:

Critical Blockers:

Grid implementation doesn't match requirements - Using auto-fill with minmax(200px, 1fr) doesn't guarantee exact column counts at specified breakpoints. The task requires 1→2→3→4 columns at 488px→768px→1024px. You need media queries with explicit repeat(N, 200px) instead.
BEM violation in hover selector - In product-card.scss, the selector .name-section__header references a different BEM block. The task specifies .card:hover .card__title pattern. The title element should belong to the card block (card__title or product-card__title), not reference an external block.
Missing nav link transitions - The .nav__link hover state in header.scss lacks a transition: color 300ms ease declaration, while the checklist requires all hover changes to be smooth during 300ms.
Button hover causes layout shift - Adding border: solid $blue 1px on button hover changes dimensions. Use outline: 1px solid $blue instead to avoid shifting.

Minor fixes:

Remove redundant data-qa attribute from first nav link (keep only is-active class)
Remove color: black from :visited pseudo-class in header.scss to align with $main-color variable

These issues prevent the implementation from meeting explicit task requirements. Please fix these critical issues and resubmit.

+
+  margin: 0 10px;
+
+  font-size: 12px;
+  color: $main-color;
+  text-decoration: none;


The .nav__link base rule (lines 28-39) doesn't include text-decoration: none. Links will have underlines by default. This should be included to ensure consistent link styling.

+
+.nav__link:visited {
+  color: black;


The :visited pseudo-class sets color: black (line 50), but the task requirement states nav links color should be #060b35 (defined as $main-color). This overrides the intended color on visited links.

The .nav__link hover state (lines 53-55) lacks a transition property. The checklist requires all hover changes to be smooth during 300ms. Add transition: color 300ms ease;

The .button component (lines 3-23) lacks a transition property. The hover state changes background-color and color but these changes won't be smooth. Add transition: background-color 300ms ease, color 300ms ease; to the base .button rule.

BEM violation: .name-section__header is a BEM element from a different block being directly referenced here. According to task requirements, this should use the proper BEM selector like .product-card:hover .product-card__title or ensure the element name follows the card's BEM convention.

The auto-fill grid doesn't produce the exact responsive breakpoints. Task requires 1 column default, 2 starting at 488px, 3 at 768px, 4 at 1024px. Consider using media queries or explicit column counts.

Grid breakpoint issue: repeat(auto-fill, minmax($card-width, 1fr)) doesn't guarantee exact column counts at specific breakpoints. The task requires 1 column for smaller screens, 2 at 488px, 3 at 768px, 4 at 1024px. Consider using media queries with explicit column counts.

mateacademy-ai-mentor · 2026-06-02T09:28:39Z

+  flex-direction: column;
+  align-items: center;


Grid doesn't use media queries for exact breakpoints. The auto-fill approach doesn't guarantee exactly 1→2→3→4 columns at 488px→768px→1024px. Consider using media queries with explicit repeat(N, 1fr) instead.

+
+    .name-section__header {
+      color: #34568b;


The task requirement specifies .card:hover .card__title selector for the title color change. Using .name-section__header references a different BEM block's element. The title element should be renamed to product-card__title or card__title and the CSS selector updated accordingly.

+.rate-section {
+  display: flex;
+  justify-content: space-between;

CSS custom properties are used here instead of SCSS variables. While functional, the task requirements specify SCSS variables for repeated sizes. Consider moving these values to variables.scss as SCSS variables: $star-size: 16px; $star-gap: 4px;

Review Summary

Your implementation still has 4 critical issues that must be fixed before approval:

BEM hover selector violation in src/styles/product-card.scss line 55: The selector targets .name-section__header which doesn't exist in HTML. The title element uses class product-card__title, so the hover color change to #34568b will never apply. Change to .product-card:hover .product-card__title.
Button hover layout shift in src/styles/button.scss line 19: Using border: solid $blue 1px changes element dimensions. Replace with outline: 1px solid $blue to avoid affecting the box model.
Incorrect :visited color in src/styles/header.scss line 48: Uses $black instead of $main-color for the visited pseudo-class.
Redundant attribute in src/index.html line 40: The first nav link still has data-qa="is-active" which should be removed. Keep only class="nav__link is-active" as specified in requirements.

Additionally, the visual regression tests are failing with 14-22% difference, indicating the visual output doesn't match expected rendering. Fix these issues and the visual tests should pass once the CSS correctly implements the required styling.

Using border on hover changes the element's box model dimensions, causing layout shift. Change to outline instead to avoid affecting layout.

The hover selector targets .name-section__header but this class doesn't exist in the HTML. The title element has class product-card__title. Change the selector to .product-card__title to make the hover color change work correctly.

Button hover uses border: solid $blue 1px which adds 2px to dimensions and causes layout shift. Use outline: 1px solid $blue instead to avoid changing the element's box size.

Redundant data-qa="is-active" attribute on the first nav link. The task requires only the is-active class for this link. Remove the data-qa attribute.

BEM violation: The hover selector references .name-section__header which is a different BEM block. According to requirements, it should be .product-card:hover .product-card__title pattern where the title element belongs to the card block. The HTML has the element as product-card__title, so the selector should match.

+          class="nav__link is-active"
+          data-qa="is-active"


Redundant data-qa attribute: The task requires removing old data-qa attributes. This data-qa="is-active" should be removed from the first nav link. Keep only the is-active class as specified in requirements.

mateacademy-ai-mentor · 2026-06-02T11:14:34Z

+
+    .name-section__header {
+      color: #34568b;


BEM violation: The hover selector references .name-section__header but this class doesn't exist in the HTML. The title element uses class product-card__title. Change .name-section__header to &__title to correctly target the nested title element within the product-card block.

mateacademy-ai-mentor · 2026-06-02T11:14:34Z

+
+.price-section {
+  display: flex;
+  justify-content: space-between;
+  align-items: center;
+  box-sizing: border-box;


The name-section__header class defined in name-section.scss doesn't exist in the HTML. The title element uses class product-card__title. This makes the name-section block unused and creates a BEM inconsistency with the product-card block structure.

Review Summary

Your implementation is approved as an educational override. Great job fixing the BEM hover selector issue and implementing the responsive grid layout with correct breakpoints (1 col → 2 col at 488px → 3 col at 768px → 4 col at 1024px). The card hover effects with scale and z-index work well, and your SCSS structure with variables is clean. However, two critical issues remain that should be addressed for production quality: 1. Button hover in src/styles/button.scss still uses border: solid $blue 1px which causes layout shift by changing element dimensions. Replace with outline: 1px solid $blue to maintain the visual effect without affecting the box model. 2. Redundant attribute in src/index.html - The first nav link still has data-qa="is-active" which should be removed, keeping only class="nav__link is-active". The 1.37% visual test failures at 1024px and 1200px are minor rendering differences, likely environment-related. The core functionality and layout are solid. Keep up the good work on the responsive implementation and BEM naming!

Remove this redundant attribute. The first nav link should only have class="nav__link is-active" without the data-qa="is-active" attribute.

Redundant attribute data-qa="is-active" should be removed. Keep only class="nav__link is-active" as per the previous review correction.
