Css not displayed properly in thumbnail

Thumbnail img for my codepen link on twitter is not displaying my ‘.laser’ object properly, but its fine once you open it


any ideas why?

p.s. yes im a total twitter noob XD

so i somehow fixed the problem by using the share button directly on codepen instead of just pasting a direct link to the page. still curious as to why it wasnt displaying properly. the thumbnail wouldnt so the ‘transform: rotate(18deg)’
