Tailwind CSS not working when on 404 page

Hi, I’m developing the 404 page base on the project what it needs and one important is the design. I am using tailwind css and apparently I could not continue the design because I found out that tailwind is not working when currently on 404 page but I see all the classes stylings I applied on the element.
Is there any workaround or why tailwind css is not running on 404 page?
