Background color gets cut off in a flex container

Question

I am trying to make a table using flexboxes that is also absolutely positioned. Each row is a standard div with display: flex Each item in each row is the flexed item. Note that there is no width set anywhere.

Why are my background colors so messed up.

I noticed that the background extends farther if there is more text in the rows and that the position is calculated from the background which is fine except that the background does not include the whole row.

Tried display: inline-flex and background-size: cover to no avail

Help, for my sanity,

Answer 1

Your primary div container is absolutely positioned.

As you mentioned: "Note that there is no width set anywhere."

In that case, the width of the absolutely-positioned div will be determined by its content.

div[style*="absolute"] {
  border: 2px dashed red;
}

<div style="z-index: 3; position: absolute; top: 50px; left: 50%; transform: translateX(-50%);">
  <div style="display: flex; background-color: rgb(173, 216, 230);">

The flex items are overflowing the container. But since the background colors are set on the container, the colors end with the container.

One solutions is to set a width on the absolutely-positioned container:

div[style*="absolute"] {
  border: 2px dashed red;
  width: 1000px; /* the sum of flex item widths */
 /* or width: 100% */
 /* or left: 0; right: 0; */
}

* {
  box-sizing: border-box;
}

<div style="z-index: 3; position: absolute; top: 50px; left: 50%; transform: translateX(-50%);">
  <div style="display: flex; background-color: rgb(173, 216, 230);">
    <div style="flex: 0 0 200px; font-family: monospace; background-color: transparent; border: 1px solid black; overflow: hidden; text-align: left; white-space: nowrap;">tesdfxt stuff</div>

Another solution, in case you don't want to set a width on the container, is to apply the background colors to the items, not the container.

div[style*="absolute"] > div:nth-child(odd) > div {
  background-color: rgb(173, 216, 230) !important;
}

div[style*="absolute"] > div:nth-child(even) > div {
  background-color: rgb(173, 216, 100) !important;
}

<div style="z-index: 3; position: absolute; top: 50px; left: 50%; transform: translateX(-50%);">
  <div style="display: flex; background-color: rgb(173, 216, 230);">
