修改css泡泡

Question

CSS:

.container {
    margin-left: 15px;
    width: 10px;
    background: #FFFFFF;
    border: 1px solid #CAD5E0;
    padding: 4px;
    position: relative;
    min-height: 10px;
    font-size:8px;
}
.container:before {
    content: '';
    display: block;
    position: absolute;
    top: 1px;
    left: 100%;
    width: 0;
    height: 0;
    border-color: transparent transparent transparent #CAD5E0;
    border-style: solid;
    border-width: 6px;
}

HTML:

<a class="container">1</a>?

有人可以向我解释如何修改这个css,以便将指针(三角形)放在盒子的左侧.

Answer 1

只需更新这两行:

.container:before {
    right: 100%;
    border-color: transparent #CAD5E0 transparent transparent;
    /* All other properties are identical */
}
