CSS Flexbox

1. You need to give your text a particular font-size.

2. You can also check the <div class="annual"></div> and make that container to have a display:flex. Also set the annual class to be a percentage of the card as well and add margin left and right to have a margin of auto.

3. You can also set the width of the button to be a percentage of the card and make it have a margin left and right of auto. That way the button will be responsive.

4. I DO NOT think you need to set the <main> tag to have a width of 50% as that will make the card to shrink in width as the viewport decreases.

I think that is all for what might be giving you problems in terms of the responsiveness.

Happy Coding David Adenusi!!!!

Just cite this at the bottom of your CSS

media screen and (max-width:550px){ .property1{ width: ... }; .property2{} }}

550px is just an example. Also there is (predictably) the option of min-width as well. Make sure there is the whitespace between 'and' and the '(' as otherwise, I believe it doesn't work.
