Why isn't bottom:0 working even when I use position relative?-CodePudding

I've got some bars that are currently aligned at the top of my page, but for some reason I can't seem to get them aligned at the bottom of the page instead.

* {
    margin: 0;
    box-sizing: border-box;
}

.wrapper {
    height: 100vh;
    width: 100vw;
    background-color: rgb(75, 71, 71);
    display: inline-flex;
}

.bar {
    height: 200px;
    width: 2px;
    bottom: 0;
    outline: 2px solid black;
    background-color: white;
}

As you can see I have bottom: 0; on the bars, but they are still aligned at the top. I've tried adding position: absolute; to the bars and position: relative; to the wrapper, but it doesn't seem to work. All it does it just put all of the bars on top of each other so it looks like just one bar.

Any help would be greatly appreciated.

CodePudding user response：

You can control the positioning of flex items via align-items and/or justify-content.

For example, adding align-items: flex-end to .wrapper does what I think you're trying to do:

* {
  margin: 0;
  box-sizing: border-box;
}

.wrapper {
  height: 100vh;
  width: 100vw;
  background-color: rgb(75, 71, 71);
  display: inline-flex;
  align-items: flex-end;
}

.bar {
  height: 200px;
  width: 2px;
  outline: 2px solid black;
  background-color: white;
}
