HTML+CSS实现页面Loading效果

如题，像Jquery等很多三方库可能自带Loading插件，那么如何自己写一个Loading效果呢？

.maskLayer {
    z-index: 10000;
    width: 100%;
    height: 100%;
    position: fixed;
    top: 0;
    right: 0;
    background: #0000004d;
    justify-content: center;
    align-items: center;
    display: flex;
}

    .maskLayer .spinner-border1 {
        width: 50px;
        height: 50px;
        border: .5em solid currentColor;
        display: inline-block;
        vertical-align: text-bottom;
        border-right-color: transparent;
        border-radius: 50%;
        -webkit-animation: spinner-border1 .75s linear infinite;
        animation: spinner-border1 .75s linear infinite;
    }


@keyframes spinner-border1 {
    0% {
        -webkit-transform: rotate(0deg);
        transform: rotate(0deg);
    }

/*    25% {
        -webkit-transform: rotate(0deg);
        transform: rotate(0deg);
    }

    50% {
        -webkit-transform: rotate(0deg);
        transform: rotate(0deg);
    }

    75% {
        -webkit-transform: rotate(0deg);
        transform: rotate(0deg);
    }*/

    100% {
        -webkit-transform: rotate(360deg);
        transform: rotate(360deg);
    }
}


@-webkit-keyframes spinner-border1 /*Safari and Chrome*/
{
    0% {
        -webkit-transform: rotate(0deg);
        transform: rotate(0deg);
    }

    100% {
        -webkit-transform: rotate(360deg);
        transform: rotate(360deg);
    }
}

/**
 * Method of setting page loading animation
 * @param {boolean} isShow
 * @returns {void}
 */
showMaskLayer(isShow) {
    $('.maskLayer').attr('hidden', !isShow);
}
