Summary of Changes

Hello @Anubhava2105, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly upgrades the user experience of the theme toggle feature. It replaces generic icons with visually distinct sun, moon, and dice SVGs for dark, light, and random themes, respectively. The random theme now boasts a unique green color scheme and an engaging shake animation on hover. Furthermore, accessibility is improved by dynamically updating the toggle button's title attribute to inform users about the current theme and the next available option.

Highlights

• Enhanced Icons: Introduced distinct SVG icons for dark (sun), light (crescent moon), and random (dice) theme modes, replacing the previous single icon.
• Random Theme Styling: Updated the random theme to feature a unique green color palette for its toggle icon and added a subtle shake animation that triggers on hover.
• Accessibility Improvements: Enhanced the theme toggle button's 'title' attribute to dynamically provide clearer context for the current theme state and the next available option.
• Dynamic Icon Display: Implemented CSS to dynamically control the visibility and transition of the appropriate theme icon based on the currently active theme.

Code Review

This pull request does a great job of enhancing the theme toggle feature with new icons for each state and a fun shake animation for the random theme. The accessibility improvement of updating the button's title attribute is also a valuable addition. My review includes a few suggestions to refine the implementation. In the JavaScript file, there's an opportunity to reduce code duplication by creating a helper function for updating the theme button's title. In the CSS, some rules for styling the new random theme icon appear to be redundant and could be simplified, and an animation rule could be removed for a minor performance optimization.

This block of code, including the themeLabels object, is a duplicate of the logic at lines 315-320. To improve maintainability and follow the DRY (Don't Repeat Yourself) principle, you could refactor this.

I'd suggest defining the themeLabels object once at a higher scope (e.g., near your other constants) and creating a small helper function to set the title. You could then call this function both on initialization and here in the click handler.

Example refactoring:

// At a higher scope in the file
const themeLabels = {
  dark: 'Currently in dark mode, click for light mode',
  light: 'Currently in light mode, click for random mode',
  random: 'Currently in random mode, click for dark mode',
};

function updateThemeButtonTitle() {
  if (elmThemeToggleButton) {
    elmThemeToggleButton.setAttribute('title', themeLabels[currentTheme] || 'Toggle theme');
  }
}

// Then you can simply call `updateThemeButtonTitle()` here and on line 314.

These styling rules for the random icon and its rectangle appear to be redundant. The color property is already set on all theme toggle SVGs in the rule at lines 46-55, and the rect element inside the SVG uses currentColor for its fill and stroke, so it should inherit the color from its parent SVG automatically. This also applies to the :hover state.

Removing these rules would make the styling more consistent with the other icons (sun-icon, moon-icon) and simplify the CSS. The existing rules for .theme-toggle svg and .theme-toggle:hover svg should be sufficient.

This rule applies the shake animation to the .random-icon on hover, regardless of the current theme. When the theme is not 'random', this icon is invisible (opacity: 0), so the browser is doing unnecessary work animating an element that isn't visible. This can be a minor performance issue.

The rule at lines 131-133 already handles the animation when the random theme is active. You can safely remove this rule to avoid the unnecessary animation.

Hey, why are these checks failing? I don't think it has anything to do with the code.

Those checks are just general failing tests we have.

There are other open issues to fix those
