我正在尝试在 ReactJS 中设置脉动动画的关键帧。我尝试在内联样式中设置关键帧，但这不起作用。

我的代码

const NewRelpyheButton = ({style = {}, open, handleOPenSettings}) => {

    var bar = {
    color: '#000',
    padding: '1em 0',
    fontSize: '20px',
    textAlign: 'center',
    cursor: 'pointer',
    position: 'fixed',
    bottom: '0',
    width: '100%',
    zIndex: '10',
    animation: 'pulse 1.2s ease-in-out',
    animationIterationCount: 'infinite',
    }

    Object.assign(style, {});
    let openModal;
    if (open) {
        openModal = <Modal><NewRelpyhe/></Modal>
    }

    return (
        <div>
        {openModal}
        <Bar color='purple' style={bar} onClick={handleOpenSettings}>
            create a new relphye site
        </Bar></div>
    )
}

我试图在 css 中模仿这一点：

.element {
  width: 100%;
  height: 100%;
  animation: pulse 5s infinite;
}

@keyframes pulse {
  0% {
    background-color: #001F3F;
  }
  100% {
    background-color: #FF4136;
  }
}

html,
body {
  height: 100%;
}
