Haddii aad isticmaasho waxyaabo ay ka mid yihiin iskudhaf (taas oo ah qaanuunka xilliyada waxqabadka GDPR) oo aad rabto inaad jilciso aagga ka dambeeya dusha sare, tusaale ahaan, waxaad badanaa la kulantaa dhibaatada xaaladda xajinta . Tusaale ahaan, haddii aad leedahay curiyeyaal gabi ahaanba taagan ama meel go'an ku jira, waxaa si lama filaan ah loogu soo bandhigayaa si ka duwan sidii iyada oo aan la helin shaandheyn la dalbaday. Laakiin dawo ayaa jirta.
Koodhka soo socdaa wuxuu muujinayaa tusaalahan. Santuuqa gadaashiisa dhab ahaan waa in lagu dhejiyaa dhinaca kore ee midig, laakiin waa la dhaqaajiyaa:

W3C waxay si cad halkan u leedahay: "Ma aha bug, waa sifo." Tilmaamuhu wuxuu sharxayaa xidhiidhka:

- filter
- transform
- backdrop-filter
- perspective
- contain
- transform-style
- will-change
Laakiin waxaa jira xal loo helo dhibkii asalka ahaa: shaandhaynta hantida CSS- ta (taas oo dhab ahaantii loo yaqaan qayb ahaan shaandhaynta meelaha ka dambeeya walxaha) waxa ay halkan ka samaynaysaa waxaad rabto. In kasta oo xaalad cusub oo is dulfuulan ay sidoo kale halkan ka abuurantay, ma khusayso maadaama aanay jirin canaasiir carruureed oo ku jira qaybta been-abuurka ah.:
