html - 带填充的边框底部全宽

Question

我试图为每个列表项实现一致的边框，但就我的嵌套列表而言，我使用填充实现了嵌套。

我有以下结果，这是很正常的行为。

这里是 JSFiddle Example

CSS

.accordion-menu {
  width: 100%;
  background: #52b3d9; }

.accordion-list {
  position: relative;
  display: none;
  width: 100%;
  /* Item submodule */
  /* Level modifiers */ }
  .accordion-list.is-root {
    display: block; }
  .accordion-list.is-opened {
    display: block; }
  .accordion-list-item {
    width: 100%;
    display: block;
    /* States */ }
    .accordion-list-item__icon {
      font-size: 1.125em;
      display: inline-block;
      vertical-align: middle; }
    .accordion-list-item__link {
      display: inline-block;
      white-space: initial;
      max-width: 70%;
      vertical-align: middle;
      color: #f7f7f7; }
      .accordion-list-item__link:visited, .accordion-list-item__link:link {
        color: #f7f7f7; }
    .accordion-list-item__post-count {
      font-size: 0.75em;
      position: absolute;
      display: inline-block;
      right: 0;
      color: #fdfdfd;
      padding: 0 0.83333em;
      margin-right: 0.83333em;
      background: #404247;
      border-radius: 10px; }
    .accordion-list-item__controls {
      padding: 0.625em 0.3125em;
      position: relative;
      width: 100%;
      white-space: nowrap;
      overflow: hidden;
      display: block;
      color: #f7f7f7; }
      .accordion-list-item__controls:hover {
        color: #FFC107; }
        .accordion-list-item__controls:hover .accordion-list-item__link {
          color: #FFC107; }
      .accordion-list-item__controls::before {

        vertical-align: middle;

        display: block;
        position: absolute;
        border-bottom: 1px solid #c8c8c8;
        bottom: 0;
        width: 100%;
        left: 0; }
    .accordion-list-item.has-children > .accordion-list-item__controls::before {
      display: inline-block;
      content: '\f054';

  .accordion-list--level-0 {

  .accordion-list--level-1 {

  .accordion-list--level-2 {
    padding-left: 20px; }

如何实现底部边框的全宽？

Answer 1

代替填充，您可以使用文本缩进:

.accordion-menu {
  width: 100%;
  background: #52b3d9;
}

ul {
  padding: 0;/* reset */
}

.accordion-list {
  position: relative;
  display: none;
  width: 100%;
  /* Item submodule */
  /* Level modifiers */
}

.accordion-list.is-root {
  display: block;
}

.accordion-list.is-opened {
  display: block;
}

.accordion-list-item {
  width: 100%;
  display: block;
  /* States */
}

.accordion-list-item__icon {
  font-size: 1.125em;
  display: inline-block;
  vertical-align: middle;
}

.accordion-list-item__link {
  display: inline-block;
  white-space: initial;
  max-width: 70%;
  vertical-align: middle;
  color: #f7f7f7;
}

.accordion-list-item__link:visited,
.accordion-list-item__link:link {
  color: #f7f7f7;
}

.accordion-list-item__post-count {
  font-size: 0.75em;
  position: absolute;
  display: inline-block;
  right: 0;
  color: #fdfdfd;
  padding: 0 0.83333em;
  margin-right: 0.83333em;
  background: #404247;
  border-radius: 10px;
}

.accordion-list-item__controls {
  padding: 0.625em 0.3125em 0.625em 0em;
  text-indent: 0.3125em;
  position: relative;
  width: 100%;
  white-space: nowrap;
  overflow: hidden;
  display: block;
  color: #f7f7f7;
}

.accordion-list-item__controls:hover {
  color: #FFC107;
}

.accordion-list-item__controls:hover .accordion-list-item__link {
  color: #FFC107;
}

.accordion-list-item__controls::before {
  display: inline-block;
  content: '\f10c';
  vertical-align: middle;
  font-family: "FontAwesome";
}

.accordion-list-item__controls::after {
  content: '';
  display: block;
  position: absolute;
  border-bottom: 1px solid #c8c8c8;
  bottom: 0;
  width: 100%;
  left: 0;
}

.accordion-list-item.has-children > .accordion-list-item__controls::before {
  display: inline-block;
  content: '\f054';
  font-family: "FontAwesome";
  color: #f7f7f7;
}

.accordion-list-item.has-children > .accordion-list-item__controls.is-opened::before {
  content: '\f078';
  color: #f7f7f7;
}

.accordion-list--level-0 {
}

.accordion-list--level-1 >li div {
  text-indent: 10px;  
}

.accordion-list--level-2 >li div {
  text-indent: 20px;
}
.accordion-menu ul li .accordion-list-item__post-count {
  text-indent:0;
