There is zero reason for you to have a cookie banner taking up a third of the page.
At this point, everyone making websites should be well aware that there is no requirement for cookie banners and that implementing such is active disrespect towards your users. Your cookie banner does not tell me you care about my privacy, it tells me you're trying to collect some type of data about me and want to annoy me into letting you sell that data.
A cookie banner is exactly as much a red flag as an obviously AI generated hero image at the top of your page. Disrespectful.
