HTML - 中心列表和图标到底部

Question

我开始使用 css grid 和 flex box，但我在尝试将此列表居中对齐时遇到了问题。

这是 codepen和片段:

* {
  box-sizing: border-box;
}
.container-shell {
  background: gray;
      display: -ms-grid;
    display: grid;
    grid-template-areas: "nav content content";
    -ms-grid-columns: 60px 1fr;
    grid-template-columns: 60px 1fr;
    -ms-grid-rows: auto;
    grid-template-rows: auto;
    height: 100vh;
}

nav {
  -ms-grid-row: 1;
-ms-grid-column: 1;
grid-area: nav;
background-color: #fff;
}

main {
 -ms-grid-row: 1;
-ms-grid-column: 2;
-ms-grid-column-span: 2;
grid-area: content;
}

.navigation-container {
      display: flex;
    align-items: center;
    justify-content: center;
    height: 100%;
}

.navigation-flex-item {
      flex: 1 0 50%;
    text-align: center;
    padding: 10px;
    min-width: 0;
}

ul {
  list-style: none;
  margin: 0;
}

.--no-padding {
  padding: 0 !important;
}

.--bottom {
  align-self: flex-end;
}

.navbar-toggle {
  margin: 14px 5px 14px 0 !important;
border: 0 !important;
transition: all .1s linear !important;
cursor: pointer;
}

.navbar-toggle {
  position: relative;
float: right;
margin-right: 15px;
padding: 9px 10px;
margin-top: 33px;
margin-bottom: 33px;
background-color: transparent;
background-image: none;
border: 1px solid transparent;
border-radius: 4px;
}

.sr-only {
  border: 0;
clip: rect(0, 0, 0, 0);
height: 1px;
margin: -1px;
overflow: hidden;
padding: 0;
position: absolute;
width: 1px;
}

.sr-only {
  position: absolute;
width: 1px;
height: 1px;
margin: -1px;
padding: 0;
overflow: hidden;
clip: rec(0, 0, 0, 0);
border: 0;
}

.icon-bar {
      display: block;
    width: 22px;
    height: 2px;
    border-radius: 1px;
  background-color: #888;
}

.icon-bar {
  width: 30px;
height: 3px;
background-color: #000;
border-radius: 0;
-webkit-transform-origin: 50% 50%;
transform-origin: 50% 50%;
transition: all .1s linear;
-webkit-transform: rotate(0);
transform: rotate(0);
}

.icon-bar:nth-child(2) {
  width: 19px;
margin-left: 11px;
}

.icon-bar + .icon-bar {
  margin-top: 4px;
}

.icon-bar:last-of-type {

如您所见，汉堡包图标与中心对齐，这很好，但文本(列表)与左侧对齐，我如何才能在不破坏汉堡包图标的情况下使文本和图像居中。我已经尝试过对齐和对齐。

Answer 1

对您的代码进行了以下更改:

1. 默认的 flex-direction 是 row - 您必须将它更改为 navigation-container 的 column。
2. 从元素 navigation-flex-item 中删除 flex: 1 0 50%。
3. 绝对将汉堡放在底部。

见下面的代码:

* {
  box-sizing: border-box;
}

body {
  background: blue; /* for illustration */
}

.container-shell {
  background: gray;
  display: -ms-grid;
  display: grid;
  grid-template-areas: "nav content content";
  -ms-grid-columns: 60px 1fr;
  grid-template-columns: 60px 1fr;
  -ms-grid-rows: auto;
  grid-template-rows: auto;
  height: 100vh;
}

nav {
  -ms-grid-row: 1;
  -ms-grid-column: 1;
  grid-area: nav;
  background-color: #fff;
}

main {
  -ms-grid-row: 1;
  -ms-grid-column: 2;
  -ms-grid-column-span: 2;
  grid-area: content;
}

.navigation-container {
  display: flex;
  align-items: center;
  justify-content: center;
  flex-direction: column; /* ADDED */
  height: 100%;
}

.navigation-flex-item {
  /*flex: 1 0 50%;*/
  text-align: center;
  padding: 10px;
  min-width: 0;
}

ul {
  list-style: none;
  margin: 0;
}

.--no-padding {
  padding: 0 !important;
}

.--bottom {
  /*align-self: flex-end;*/
  position: absolute; /* ADDED */
  bottom: 0; /* ADDED */
}

.navbar-toggle {
  margin: 14px 5px 14px 0 !important;
  border: 0 !important;
  transition: all .1s linear !important;
  cursor: pointer;
}

.navbar-toggle {
  position: relative;
  float: right;
  margin-right: 15px;
  padding: 9px 10px;
  margin-top: 33px;
  margin-bottom: 33px;
  background-color: transparent;
  background-image: none;
  border: 1px solid transparent;
  border-radius: 4px;
}

.sr-only {
  border: 0;
  clip: rect(0, 0, 0, 0);
  height: 1px;
  margin: -1px;
  overflow: hidden;
  padding: 0;
  position: absolute;
  width: 1px;
}

.sr-only {
  position: absolute;
  width: 1px;
  height: 1px;
  margin: -1px;
  padding: 0;
  overflow: hidden;
  clip: rec(0, 0, 0, 0);
  border: 0;
}

.icon-bar {
  display: block;
  width: 22px;
  height: 2px;
  border-radius: 1px;
  background-color: #888;
}

.icon-bar {
  width: 30px;
  height: 3px;
  background-color: #000;
  border-radius: 0;
  -webkit-transform-origin: 50% 50%;
  transform-origin: 50% 50%;
  transition: all .1s linear;
  -webkit-transform: rotate(0);
  transform: rotate(0);
}

.icon-bar:nth-child(2) {
  width: 19px;
  margin-left: 11px;
}

.icon-bar+.icon-bar {
  margin-top: 4px;
}

.icon-bar:last-of-type {
  width: 19px;
  margin-right: 11px;
}
