a comment might help the reviewer understand the naming conventions that you'd follow for the project. while there seems to be careful thought put into the naming style, a comment would help understand what to follow or how to follow.

there's already a h1 selector that's used in the same piece of code. there seems to be a duplicate.

I totally understand the readability of this code but maybe formatting elements in a way that they are on the same line instead of a new line for each would help. there actually could be a lot more than 6 elements.

This line of code can be formatted more appropriately.

There could be some consistency in the way spaces are used after a selector

having the selectors on multiple lines might not be a great idea. Imagine if there were a lot more than 4.

There's an empty space that might not be needed.

You might want to consider consistency in formatting. In the first one the closing tag of list item is placed on a new line and in the next one it is placed right after the content.

Suggestion : Consider using class name over id name if the blocks belong to the same type and would eventually follow the same styling.

You've written a very clean and readable code. Loved it.

there no space between content and tags

increase the size of the button to make it more readable

missing carousel dots

suggestion : could have href on the same line as link

Html code looks well formatted

Can comment the card two in color gradient as grayscale was mentioned to be for trail purpose only

missing point : h1 font size overriding

missing comment header in index.html

Title needs to describe the webpage

there's an extra space before the content begins

the formatting here makes it difficult to identify where the paragraph tag closes.

Loved the fact that you've added comments in the code.

suggesting to start a block level element on a new line since it might not have any relation to the horizontal line that is being used for demarcation

keep the tag along with the content it is related to

it would be better to start a new block element on a new line for better readability

indentation will help for the code be readable when the code is larger

It is always better to have 'alt text' for an image describe what the image is as it is best for accessibility and when the image isn't available.

for a cleaner code, let new tags begin on a new line.
