html - 如何将水平条转换为响应式？

Question

我有一个包含 4 个或更多元素的单杠。我想做的是，当浏览器调整水平栏的每个元素及其各自元素的大小时，我正在使用 twitter-bootstrap 4，但默认情况下它似乎也不起作用

.post-content-wrapper {
    padding: 20px;
    margin-bottom: 2em;
    position: relative;
    max-width: 900px;
    margin-left: auto;
    margin-right: auto;
    background-color: #f7f7f7;
    border-radius: 7px;
    box-sizing: border-box;
}


.flex7 {
    display: flex;
    height: 300px;
    justify-content: space-between;
    align-items: flex-end;
}

.flex {
    background-color: #f7f7f7;
    border-radius: 3px;
    padding: 20px;
}

.flex7-child-1 {
    height: 40%;
    position: relative;
}

切换前

切换后，即使在不破坏元素的情况下调整布局大小时，我也希望拥有相同的位置

这里有一个更好的方法来为您的单杠实现响应一致的样式。请注意，每个 .flex7-child-#:before 的单独样式已被删除，所有 .flex7-child 元素现在都使用 flexbox。

.post-content-wrapper {
    padding: 20px;
    margin-bottom: 2em;
    position: relative;
    max-width: 900px;
    margin-left: auto;
    margin-right: auto;
    background-color: #f7f7f7;
    border-radius: 7px;
    box-sizing: border-box;
}


.flex7 {
    display: flex;
    height: 300px;
    justify-content: space-between;
    align-items: flex-end;
}

.flex {
    background-color: #f7f7f7;
    border-radius: 3px;
    padding: 20px;
}

/* Pay attention to below */

.flex7-child {
    display: flex;
    flex-direction: row;
    justify-content: center;
}
.flex7-child:before {
    content: '';
    position: relative;
    background-image: url('https://via.placeholder.com/50.png');
    background-repeat: none;
    background-position: center center;
    top: -70px;
    background-size: contain;
    display: block;
    width: 50px;
    height: 50px;
}

/* Pay attention to above */

.flex7-child {
    width: 14%;
}
.child {
    border-radius: 3px;
    background-color: #A2CBFA;
    border: 1px solid #4390E1;
    box-sizing: border-box;
    box-shadow: 0 2px 2px rgba(0,90,250,0.05), 0 4px 4px rgba(0,90,250,0.05), 0 8px 8px rgba(0,90,250,0.05), 0 16px 16px rgba(0,90,250,0.05);
}
.flex7-child-1 {
    height: 40%;
}
.flex7-child-2 {
    height: 50%;
}
.flex7-child-3 {
    height: 60%;
}

.flex7-child-4 {
    height: 20%;
}

.flex7-child-5 {
    height: 30%;
}
