I'm trying to cause an (unsuccessful) effect of fading the image using the following code:
@-webkit-keyframes fundo {
10%{
-webkit-filter: grayscale(10%);
-moz-filter: grayscale(10%);
-ms-filter: grayscale(10%);
-o-filter: grayscale(10%);
filter: grayscale(10%);
}
50%{
-webkit-filter: grayscale(50%);
-moz-filter: grayscale(50%);
-ms-filter: grayscale(50%);
-o-filter: grayscale(50%);
filter: grayscale(50%);
}
100%{
-webkit-filter: grayscale(100%);
-moz-filter: grayscale(100%);
-ms-filter: grayscale(100%);
-o-filter: grayscale(100%);
filter: grayscale(100%);
}
img{
-webkit-filter: fundo .5s infinite;
-moz-filter: fundo .5s infinite;
-ms-filter: fundo .5s infinite;
-o-filter: fundo .5s infinite;
filter: fundo .5s infinite;
}
