Main Content Wont Center

[mkailbowdy]

For some reason, the main content wont center after applying the .hidden-detail class. Here’s a picture of the result I get from applying .hidden-detail. Anyone know how I can fix this?

Hello @mkailbowdy!

I think we can get this sorted out.
Would you mind posting your CSS file?

Thanks,
Chris

I am having this issue as well, so I will post my css here rather than starting a new thread.

Here is my styles.css:

@font-face {
    font-family: 'airstreamregular';
    src: url('fonts/Airstream-webfont.eot');
    src: url('fonts/Airstream-webfont.eot?#iefix') format('embedded-opentype'),
         url('fonts/Airstream-webfont.woff') format('woff'),
         url('fonts/Airstream-webfont.ttf') format('truetype'),
         url('fonts/Airstream-webfont.svg#airstreamregular') format('svg');
    font-weight: normal;
    font-style: normal;
}

@font-face {
    font-family: 'lakeshore';
    src: url('fonts/LAKESHOR-webfont.eot');
    src: url('fonts/LAKESHOR-webfont.eot?#iefix') format('embedded-opentype'),
         url('fonts/LAKESHOR-webfont.woff') format('woff'),
         url('fonts/LAKESHOR-webfont.ttf') format('truetype'),
         url('fonts/LAKESHOR-webfont.svg#lakeshore') format('svg');
    font-weight: normal;
    font-style: normal;
}

html, body {
  height: 100%
}

body {
  display: flex;
  flex-direction: column;

  font-size: 10px;
  background: rgb(149, 194, 215);

  font-size: 40px;
}

.hidden-detail .detail-image-container {
  display: none;
}

.hidden-detail .thumbnail-list {
  flex-direction: column;
  align-items: center;
}

.hidden-detail .thumbnail-item {
  max-width: 80%;
}

@media all and (min-width: 768px) {
  .main-content {
    flex-direction: row;
    overflow: hidden;
  }

  .thumbnail-list {
    flex-direction: column;
    order: 0;
    margin-left: 20px;
  }

  .thumbnail-item {
    max-width: 260px;
  }

  .thumbnail-item + .thumbnail-item {
    margin-top: 20px;
  }
}

I am attaching two sceenshots of the dev tools showing that the proper css styles are applied.

Correct: it works as expected on a mobile sized browser. but not when the browser is at a large width.

Hi @TitusG, it looks like you may have forgotten to remove width:120px from .thumbnail-item (we replaced it with min-width and max-width).

[drl]

Hi. I add the statement as follow:

.hidden-detail .main-content {
    justify-content: center;
}

and it works.

I encountered the same issue. The “justify-content: center” descendant tag worked.

[FreddieBryan]

Same thing I’ve had with this website here , but my team somehow resolved it. I still don’t know how. Any ideas?

[rosesoftwareshop]

I just ran into this. The justify-content fix mostly worked (the content wasn’t quite centered), but I didn’t understand why it worked, so I wanted to figure out a flexbox-only solution. I’m sharing what I found here in case anybody’s interested.

Fix:
After a couple hours of debugging, I was able to figure out that the flex-grow property needed to be updated (to a lesser extent the margin-left property did too):

.hidden-detail .thumbnail-list {
  flex-grow: 1; /* Allows width of .thumbnail-list to grow. */
  flex-direction: column;
  align-items: center;
  margin-left: initial; /* Removes left margin added by the @media query. */
}

The flex-grow property tells the browser to assign some of the remaining space to the .thumbnail-list when there’s extra space available. The margin-left property is being reset to its default value of 0, overriding the 20px value set in the @media query. Without the margin-left fix, the content isn’t quite visually centered – it’s slightly too far to the right.

Explanation:
When the width of the browser window was 768px or greater, the @media query was getting triggered, changing the flex-direction of .main-content to row. This lays out the .thumbnail-list on the left and the .detail-image-container on the right. The flex property of .thumbnail-list was declared earlier in styles.css to be "0 1 auto". The first value, 0, is shorthand for the flex-grow property. A value of 0 means none of the remaining space is allocated to the element once it reaches its intrinsic size. I think this was causing all of the remaining space to be allocated to .detail-image-container (even though it was set to display:none;) once .thumbnail-list reached its intrinsic size. I reproduced the issue on Chrome, Firefox, and Safari. All three browsers stopped increasing the size of the .thumbail-list once its width reached 802px. I’m not sure how this magic number is computed but I guess this was determined be the intrinsic width of the .thumbnail-list by all three browsers.

Anyway, that was quite a fun debugging session. Hope this helps!
