Use proven defaults that make your page simple to digest:
Put content into container with limited width (1024px – 1280px)
Use 80px or 48px bold font for hero.
Most of the websites use Inter for both title and copy. Use gradient background for your title texts on dark mode.
Use few consistent fonts between all the titles, sections and copy. Line-height and letter-spacing matters a lot for your big fonts.
Keep the copy readable and concise. Never put more than 70 characters in 1 line. For titles it as little as 6-7 words per line.
Keep consistent paddings and margins between sections and elements based on 4px multiplied (or 8px)
Use 12-column structure for the page. Use 2-column, 3-column, 4-column grids for sections.
Use bento grids for feature presentations to make your page look PRO. It's when some items in your grid occupy more than 1 column or 1 row.
Use limited colors (primary accent color + secondary accent colors)
Render media the same way. Put media into gradients background, keep border radius and box-shadows consistent
Use very few and subtle animations. Usually used for hero titles appearance (fade + fly)
