A THEME SWITCHER static website with both light and dark mode and a solarised option.
I've used semantic HTML by applying elements such as <nav>, <header> and <main> instead of just <div class="something">.
I used only CSS for the dropdown on the navbar.
The header's background shape is made with clip-path: polygon();.
I've used CSS --variables to update the colours.
Media queries for responsiveness.
Rainbow effect while hovering on the image.
DOM elements and event handlers to toggle the desired option.
localStorage to apply the cached user's theme on refresh.
