使文本列表位于页脚上方,但能够在合成栏下方滚动

twitter-bootstrap-3 css html jquery

我试图滚动一个消息列表,使其位于撰写栏下方,但当添加新消息时,它们应该添加到撰写栏的正上方。要快速演示我的意思,请参见下面的图片 link .

我无法根据内容大小控制内部div元素的宽度。

.contentContainer {
  margin: 0;
  padding: 0;
  margin-top: 68px;
  height: calc(100vh - 68px);
  display: block;
  overflow-y: auto;
}

.content {
  display: flex;
  flex-direction: row;
  flex-wrap: nowrap;
  height: inherit;
}

.messageArea {
  flex-grow: 1;
  /*min-width: 400px;*/
  height: inherit;
  position: relative;
}

.scrollingMessagesList {
  height: inherit;
  overflow-x: hidden;
  overflow-y: auto;
  transform: translateZ(0);
}

.outer {
  margin: 0 auto;
  margin-top: 18px;
  margin-bottom: 142px;
  height: 414px;
  position: relative;
  background-color: #78909c;
}

.inner {
  margin: 0 20px;
  height: inherit;
  background-color: darkkhaki;
  display: flex;
  flex-direction: column-reverse;
  align-items: flex-end;
}

.inner p {
  width: auto;
  max-width: 100%;
  outline: none;
  padding-bottom: 2px;
  background-color: greenyellow;
}

.composeBar {
  z-index: 1029!important;
  border: none;
  bottom: 20px;
}

.compose {
  height: 52px;
  border-radius: 26px;
  background-color: white;
  box-shadow: 0 1px 5px 0 rgba(0, 0, 0, .16), 0 4px 4px 0 rgba(0, 0, 0, .10), 0 3px 3px 0 rgba(0, 0, 0, .08);
  ;
}

$(document).ready(function() {
  function setHeight() {
    windowHeight = $(window).outerHeight();
    $('.inner').css('min-height', windowHeight - 68);

    setHeight();
