• There's a typo in the comment. "assertion]" should be "assertion" without the closing bracket.

    // insert test assertion]

src/scripts/hero-action.ts:202

• There's an extra space in the class attribute before the closing angle bracket. While this won't break functionality, it's inconsistent with standard HTML formatting. Consider removing the space: <i class="fas fa-moon"></i> instead of <i class="fas fa-moon" ></i>.

const darkModeHTML = `<i class="fas fa-moon" ></i>`

src/scripts/hero-action.ts:203

• There's an extra space in the class attribute before the closing angle bracket. While this won't break functionality, it's inconsistent with standard HTML formatting. Consider removing the space: <i class="fas fa-sun"></i> instead of <i class="fas fa-sun" ></i>.

const lightModeHTML = `<i class="fas fa-sun" ></i>`

src/components/ModeToggleButton.astro:5

• The toggle button is missing an accessible label. Screen readers need text to announce what this button does. Add an aria-label attribute to describe the button's purpose, such as aria-label="Toggle dark mode" or use a visually-hidden span with descriptive text.

<button class="button toggle-button" id="darkModeToggle">

src/components/Footer.astro:5

• The footer element uses the class "hero-section" which is semantically confusing since it's not part of the hero section but rather a footer. While this reuses existing styles, it creates a maintainability issue where the class name doesn't match its purpose. Consider creating a dedicated "footer-section" class or renaming "hero-section" to something more generic like "centered-section" if it's meant to be reused.

<footer class="hero-section">

src/components/Footer.test.ts:23

• The test description has a grammatical error. "component display" should be "component displays" (with an 's') to match standard grammar conventions.

  test("component display the correct DOM component", async () => {

src/components/ModeToggleButton.test.ts:20

• The test only checks if the component renders with the correct class names and moon icon. Consider adding a test to verify the button has the correct ID ("darkModeToggle") since the JavaScript in hero-action.ts depends on this ID to attach the click event listener. Without this ID, the dark mode toggle functionality would break.

  test("component is rendered correctly", async () => {
    // render component
    const result = await container.renderToString(ModeToggleButton)

    // Insert test assertion
    expect(result).toContain('class="button toggle-button"')
    expect(result).toContain('class="fas fa-moon"')
  })

src/styles/global.css:479

• The toggle button is missing display: flex in its CSS definition, but relies on the child i element having display: flex. While the icon will render correctly, the button itself should explicitly set display: flex to ensure proper alignment behavior, especially since it has align-items: center which only works on flex containers.
