Como criar uma simples animação de ondulação “wobble” no CSS 3 utilizando keyframes e propriedades como transform e animation-duration.
Exemplo animação de ondulação
Efeito de ondulação vertical
Passe o mouse
Efeito de ondulação horizontal
Passe o mouse
CSS utilizado para ondulação vertical
A animação é executada em 6 passos, altere os valores em translateY(…px) para ajustar o movimento.
Para alterar a velocidade dos movimentos mude o valor de animation-duration (valor em segundos).
@-webkit-keyframes wobble-vertical {
16.65% {
-webkit-transform: translateY(8px);
transform: translateY(8px);
}
33.3% {
-webkit-transform: translateY(-6px);
transform: translateY(-6px);
