How to use Bootstrap-style layouts in Bubble

You can’t drop Bootstrap itself into Bubble, but you can recreate Bootstrap‑style responsive layouts by using Bubble’s Container layout engine (Rows, Columns, and Alignments) because Bubble’s responsive engine already behaves very similarly to Bootstrap’s flexbox grid. You simply map Bootstrap ideas like “row”, “column”, “container”, and “breakpoints” to Bubble groups set as Row or Column with min/max widths.

Key idea: Bootstrap concepts mapped to Bubble

Bubble doesn’t use external CSS frameworks because the responsive engine is built‑in. But the same layout patterns work if you set up your groups correctly:

• Bootstrap container → A Bubble Group with layout = Column (max-width optional)
• Bootstrap row → A Bubble Group with layout = Row
• Bootstrap column (col-6, col-4, etc.) → Child groups inside a Row with % width or fixed min/max width
• Breakpoints (sm, md, lg) → Bubble’s responsive rules + min width + “allow to shrink”

How to build a Bootstrap-like layout in Bubble

Set up a Container (your “bootstrap container”). Create a Group, set layout = Column, and give it a max width if you want the classic centered look (ex: 1200px). Enable “align to parent” if needed.

• Create a Group inside it set to layout = Row. This is your Bootstrap “row”.
• Inside the row, add multiple Groups. These are your “columns”. Set layout = Column inside each one.
• To simulate col‑4 / col‑6 behavior, set each column’s width to something like 33% or 50% and allow it to shrink/grow.
• Use “Min width” to define breakpoints. Example: set a min width of 250px so columns stack when the page gets narrow.

Example: Bootstrap-like two-column layout

// Container (Column)
Group A
  layout: column
  max width: 1200
  align: center

// Row (Row)
Group B
  layout: row
  gap: 20

// Column 1 (Column)
Group C
  layout: column
  width: 50%
  min width: 260 // stacks on mobile

// Column 2 (Column)
Group D
  layout: column
  width: 50%
  min width: 260 // stacks on mobile

Tips for making it feel truly Bootstrap-like

• Use “fit width to content” OFF so elements act like flexbox blocks.
• Use gaps instead of margins to keep spacing consistent.
• Use conditional formatting if you need breakpoint-specific behavior (ex: change width below 600px).
• If you need true Bootstrap components like modals or navbars, recreate them using Bubble Groups and conditionals rather than adding Bootstrap code.
