Make 2 small changes to an existing Shopify Template

Hello, I have an existing Shopfiy Theme that requires two small customizations. 1) I would like to change the height of the header elements as seen in the two screenshots attached (header_current and header_desired) and 2) I would like take the product details from below the product images on the product_grid and have them appear inside the product image instead (as the current quick view does right now). You can see a screenshot with notes attached (new_product_grid). All changes to liquid files and CSS must be commented with <!-- DEV CHANGE --> <!--END DEV CHANGE --> and the original code must be kept on the page, but commented out with <!-- ORIGINAL CODE [original code] END ORIGINAL CODE --> All quotes must include the secret word "boxers" to confirm that you have read this entire project description. Any quote that does not include the secret word will be ignored. Thanks!
