REST Countries API | LocalStorage | Theme Switch | Vanilla JS | SCSS

Nice work Folarin! Nice addition of the hover animation on the country blocks. A couple remarks and improvements from my side:

1. The country blocks in the overview feel a little bit messy because of the different heights and sizes:

• I would suggest setting a suitable fixed height on the flag images.
• Make the flex items 'align-self: stretch' so all items in a row are equal height.

1. I feel like the font-family is different then the design. Maybe that's design choice of your own. But be sure to set a font-family on the input and select elements because those ones are using the default browser font right now.

2. Try to add thousand separators to the population numbers to make them more readable. (So 27,657,145 instead of 27657145)

3. The country detail page keeps showing a loading spinner at the bottom. Even though i feel like everything has been loaded.

4. I noticed a lot of console.logs when i used the search function. You might wanna remove that when you clean up your code.

Your javascript code looks really well structured, nice job!
