Bootstrap grid layout

I want the main (and all children contained) to occupy “col-md-8” width of the page, and the secondary (and its children) to occupy the rest.

    <div class="container" id="main-content">
    </div>

    <div class="container" id="secondary info">
    </div>

ChatGPT

To achieve a main section that is col-md-8 wide and a secondary section that occupies the remaining col-md-4, you need to use Bootstrap’s grid system, which requires wrapping columns inside a .row.

✅ Correct Bootstrap Layout

<div class="container">
    <div class="row">
        <!-- Main Content -->
        <div class="col-md-8" id="main-content">
            <!-- all children here will stay inside the 8-column width -->
        </div>

        <!-- Secondary Content -->
        <div class="col-md-4" id="secondary-info">
            <!-- children remain within the 4-column width -->
        </div>
    </div>
</div>

⚠️ Notes

• IDs cannot contain spaces, so I changed:
  id="secondary info" → id="secondary-info"
• Both sections must be inside the same .row for the grid to work.
• The total width per row should be 12 columns in Bootstrap (8 + 4).

If you want spacing between columns

Replace col-md-4 with col-md-3 and use col-md-1 as a spacer, or use Bootstrap’s gutter utilities, e.g.:

<div class="row g-3"> ... </div>

Yes, you can definitely simplify this template and merge some divs. You’re also mixing Bootstrap grid with custom flex outside the grid, which is why it feels a bit over-wrapped.

Below is a cleaned-up version that:

• Puts main and secondary content in the same Bootstrap row (col-md-8 + col-md-4).
• Removes unnecessary wrapping <div>s.
• Replaces many inline styles with Bootstrap utility classes.
• Fixes some semantic issues (e.g. <ul> with <div> inside).

What changed / where divs were merged

1. Unified layout

   • Secondary content is now inside the same .container and .row and uses col-md-4 instead of a separate div style="width:auto" with manual flex.

2. Removed unnecessary wrappers

   • Dropped:
     • The inner .row mb-4 align-items-center that only contained one child.
     • The #summary-group div that only wrapped a single <p>.
     • The inner .col wrappers around media and description (they weren’t inside a .row anyway, so they were incorrect Bootstrap).

3. Simplified carousel logic

   • Replaced repeated if loop.index0 == 0 blocks with loop.first.
   • One button / item template with conditional active class and aria-current.

4. Replaced inline styles with Bootstrap utilities where reasonable

   • style="display:flex; gap:24px; flex-direction:column;" → class="d-flex flex-column gap-3", etc.
   • Kept inline object-fit style because Bootstrap doesn’t provide that directly.

5. Semantic / structural fixes

   • <ul> now contains <li> elements instead of bare <div>s.
   • Secondary content wrapped in <aside> to signal it’s complementary to the main content.

If you tell me which Bootstrap version you’re on (4 vs 5), I can tweak the utility classes to match exactly and, if you want, also move all remaining inline styles (like object-fit) into a small CSS snippet.

1. what if i want this div to always have the minimum possible width, instead of md-4?

2. i dont want bullet-point

Nice, easy tweaks 😄

1️⃣ Make the side div “minimum possible width”

Instead of col-md-4, use Bootstrap’s auto-width column, and let the main content flex to fill the rest.

Change this:

<div class="row justify-content-between">
  <div class="col-md-8" id="main-content">
    ...
  </div>

  <aside class="col-md-4">
    ...
  </aside>
</div>

to this:

<div class="row">
  <!-- Main: takes all remaining space -->
  <div class="col-md" id="main-content">
    ...
  </div>

  <!-- Side: only as wide as its content -->
  <aside class="col-md-auto">
    ...
  </aside>
</div>

• col-md → flexible column, fills leftover space.
• col-md-auto → width based on content (minimum possible, up to row width).
• On small screens you can stack them full-width if you want:

<div class="row">
  <div class="col-12 col-md" id="main-content">...</div>
  <aside class="col-12 col-md-auto">...</aside>
</div>

---

2️⃣ Remove bullet points

You already had the right idea with <ul class="list-unstyled">. In Bootstrap, that should remove bullets and left padding.

Example for commissioner:

<section id="commissioner">
  <h4 class="h4 mb-3">{{ commissioner.role }}</h4>

  <ul class="list-unstyled list-line mb-0">
    <li>
      <a href="{{ commissioner.url }}" target="_blank" class="link-1">
        {{ commissioner.name }}
      </a>
    </li>
  </ul>
</section>

Same pattern for shows and credits:

<ul class="list-unstyled list-line mb-0">
  {% for item in collaborators %}
  <li class="mb-2">
    <div>{{ item.role }}</div>
    <a href="{{ item.url }}" target="_blank" class="link-1">
      {{ item.name }}
    </a>
  </li>
  {% endfor %}
</ul>

If you really don’t want lists at all, you can swap ul/li for plain divs:

<div class="list-line d-flex flex-column gap-2">
  {% for item in collaborators %}
  <div>
    <div>{{ item.role }}</div>
    <a href="{{ item.url }}" target="_blank" class="link-1">
      {{ item.name }}
    </a>
  </div>
  {% endfor %}
</div>

But structurally, keeping <ul> + list-unstyled is nicer for accessibility.

---

If you paste your current commissioner / shows / credits block, I can rewrite it exactly with col-md-auto + no bullets.

what is

<aside> (lowercase!) is just an HTML5 semantic tag – like <header>, <footer>, <main>, etc.

It’s used for content that is related but not the main flow of the page. Typical examples:

• Sidebars
• Pull quotes
• Extra info boxes
• Related links / “See also” sections

So in your case, your right-hand “secondary” block (commissioner, shows, credits) is perfect for an <aside>.

Example:

<div class="row">
  <div class="col-md" id="main-content">
    <!-- main project content -->
  </div>

  <aside class="col-md-auto" id="side-info">
    <!-- secondary info: commissioner, shows, credits -->
  </aside>
</div>

If you prefer, you can absolutely just use a <div>:

<div class="col-md-auto" id="side-info">
  ...
</div>

Functionally in the browser they behave almost the same; <aside> just tells browsers, screen readers, and other tools: “this is secondary/side content.”

i want to keep the li but remove the indent

ChatGPT

To keep the <li> elements but remove the left indent, you should apply Bootstrap’s list-unstyled and optionally reset margin/padding.

✅ Easiest solution (Bootstrap way)

<ul class="list-unstyled mb-0">
    <li>Item</li>
    <li>Another</li>
</ul>

list-unstyled removes:

• bullets
• left padding
• indentation

This is usually enough.

---

✅ If you still see indentation (some themes override it)

Add Bootstrap utilities for margin/padding reset:

<ul class="list-unstyled m-0 p-0">
    <li class="mb-2">
        {{ item.role }}
    </li>
</ul>

---

✅ If you want only li indent removed, but keep bullets

You can keep bullets but remove indent like this:

<ul class="ps-0">
    <li class="ms-0">Keep bullets, no indent</li>
</ul>

• ps-0 → remove left padding on the <ul>
• ms-0 → remove left margin on <li>

---

Summary

Want	Use
remove bullets + indent	class="list-unstyled"
remove indent only	class="ps-0" (and ms-0 on li if needed)
remove all spacing	class="m-0 p-0"

If you paste one list (commissioner, shows, or credits), I can give you the exact cleaned-up line.
