Positioning last div at end, when using flex and flex-wrap

Hi! See screenshot for reference. I'm banging my head against this one. I have a flex container with flex-wrap enabled. I want the last button (class "close-button") to show at the bottom right corner of the flex-container. The number of buttons in the container can be anything. I also want the container height to only be the needed height. So if there are only 3 room buttons, it should only be high enough to show the three buttons plus the close buttons. I can't get this to work without setting the container to a fixed height. Any input is appreciated. Thanks in advance. PS. This is my first post, so please let me know if this should be structured in better way

<div class="rooms">
  <div class="rooms-title">Xxxxxx</div>
  <div class="room-buttons">
    <div class="room-button" v-for="number in x">
      <SharingIcon></SharingIcon>
      <BaseButton></BaseButton>
    </div>
    <div class="close-button">
      <MyButton title="Stäng"></MyButton>
    </div>
  </div>
</div>

<div class="rooms">
  <div class="rooms-title">Xxxxxx</div>
  <div class="room-buttons">
    <div class="room-button" v-for="number in x">
      <SharingIcon></SharingIcon>
      <BaseButton></BaseButton>
    </div>
    <div class="close-button">
      <MyButton title="Stäng"></MyButton>
    </div>
  </div>
</div>

.rooms {
  height: 100%;
  border-left: 1px solid var(--col-line);
}

.room-buttons {
  display: flex;
  flex-direction: column;
  flex-wrap: wrap;
  justify-content: space-between;
  max-height: calc(100vh - 16rem);
}
.room-button {
  display: flex;
  align-items: center;
  gap: .5rem;
  padding: .75rem 1rem 0;
  border-left: 1px solid var(--col-line);
}
.close-button {
  margin-top: auto;
  align-self: flex-end;
}

.rooms {
  height: 100%;
  border-left: 1px solid var(--col-line);
}

.room-buttons {
  display: flex;
  flex-direction: column;
  flex-wrap: wrap;
  justify-content: space-between;
  max-height: calc(100vh - 16rem);
}
.room-button {
  display: flex;
  align-items: center;
  gap: .5rem;
  padding: .75rem 1rem 0;
  border-left: 1px solid var(--col-line);
}
.close-button {
  margin-top: auto;
  align-self: flex-end;
}

Wow! This was quite a thinker! 😂 First, here's the code to fix it:

.room-buttons {
  display: flex;
  flex-direction: column;
  flex-wrap: wrap;
  justify-content: space-between;
  height: 100svh; /* Force the height to always be maximum */
  max-height: calc(100vh - 16rem); /* Final height will still be controlled by max-height */
}
.room-button {
  display: flex;
  align-items: center;
  gap: .5rem;
  padding: .75rem 1rem 0;
  border-left: 1px solid gray;
}
.close-button {
  margin-top: auto;
  /* You do not need the `align-self` property */
}

.room-buttons {
  display: flex;
  flex-direction: column;
  flex-wrap: wrap;
  justify-content: space-between;
  height: 100svh; /* Force the height to always be maximum */
  max-height: calc(100vh - 16rem); /* Final height will still be controlled by max-height */
}
.room-button {
  display: flex;
  align-items: center;
  gap: .5rem;
  padding: .75rem 1rem 0;
  border-left: 1px solid gray;
}
.close-button {
  margin-top: auto;
  /* You do not need the `align-self` property */
}

I want to try and give an explanation, but only if you actually need it

Thanks @EIO! But then we will always be at max height, so if we only have 3 buttons, the height would still be max-height.

EIO•2mo ago

That's where the max height you set comes into play. And that's how the height of the div is controlled.

Niklas Westman•2mo ago

The problem is I want it to be responsive based on the content. That's why I'm using max-height. As it is now I could just omit max-height and set height to calc(100vh - 16rem)

EIO•2mo ago

Oh, I see your point. But even with a single column, you would still need a fixed height to get the space between the regular buttons and the close button

Niklas Westman•2mo ago

I think I was a little vague in my initial description. I only want the space between when it is "needed". When there is only one column, no space will be needed.
