Sifa backdrop-filter

Sifa backdrop-filter inaruhusu kutumia vichujio (uwazi, mabadiliko ya tofauti, athari za rangi) kwa eneo lililo nyuma ya kipengele. Hii inaunda athari ya "kioo" au "kioo kilichochakaa".

Kiambishi

kichagua {
	backdrop-filter: none | <kichujio> [<kichujio>]*;
}

Thamani

Thamani	Maelezo
`none`	Vichujio havatumiki (thamani chaguomsingi).
`blur()`	Inatumia athari ya uwazi (kwa mfano: `blur(5px)`).
`brightness()`	Hubadilisha mwangaza wa msingi (kwa mfano: `brightness(0.5)`).
`contrast()`	Hubadilisha tofauti ya msingi (kwa mfano: `contrast(200%)`).
`drop-shadow()`	Inaongeza kivuli kwenye msingi.
`grayscale()`	Hubadilisha msingi kuwa vivuli vya kijivu (kwa mfano: `grayscale(100%)`).
`hue-rotate()`	Hubadilisha toni ya rangi ya msingi (kwa mfano: `hue-rotate(90deg)`).
`invert()`	Inageuza rangi za msingi (kwa mfano: `invert(100%)`).
`opacity()`	Hubadilisha uwazi wa msingi (kwa mfano: `opacity(50%)`).
`sepia()`	Inatumia sepia kwenye msingi (kwa mfano: `sepia(100%)`).
`saturate()`	Hubadilisha ukolezo wa rangi za msingi (kwa mfano: `saturate(200%)`).

Inawezekana kuchanganya vichujio kadhaa, kukiwaorodhesha kwa kupita nafasi.
