Šis metodas naudoja neigiamas z indekso reikšmes kai kuriems pseudo elementams. Tai reiškia, kad jie gali atsilikti nuo kitų elementų, kurių fonas yra nepermatomas, o tai sugadina efektą. Norėdami tai išspręsti, turėsite įsitikinti, kad tiesioginiame juostelių pagrindiniame elemente nėra pritaikytas fonas ir santykinis poslinkis su teigiamu z indeksu. Jei reikia, naudokite papildomą pakuotę.
