Ooh tailwind is giving you some issues here I think... as i resize the screen , the input and button become all stretched out and are misaligned with the section above.
I think you're misusing section element a bit here to be honest... I would call this whole solution a section maybe but not the section within section you have here.
As already suggested, the h1 should all be in one h1 tag. You can use spans within it for styling.
And two important points around the logo: 1) It's not navigation. Even if wrapped in a link, you wouldnt normally place the logo inside a nav element. 2) It's so so so important to give the logo alt text. That's the most important thing on this whole page in fact - what is the name of the product/site. If a user can't know that, the page's purpose fails.
I'd place the email input a button inside a form element too tbh.
I hope these are helpful tips. I'm a bit tired tonight so just bashing them out - i hope I've explained ok for you.
Best of luck with it!
