Make your site work well on mobile
Some visitors will discover your site on a phone, so its content should remain easy to read on a narrow screen.
Check the mobile preview
Pay special attention to long headings, columns, images, and buttons. An element that lines up well on a computer may take up too much space on a phone.
Make navigation easy
Avoid tiny text, links placed too close together, and buttons that are difficult to tap. Images should not overflow the screen.
Test the published site
Open your site on a real phone. Try the navigation, submit a test form, and check the interactive elements.
