How to make a Bubble app mobile responsive

The simple answer: in Bubble, you make your app mobile responsive by using the Responsive Editor, placing elements inside containers (Row/Column groups), controlling how those containers shrink, grow, wrap, and align as the screen gets smaller, and setting proper min widths so your layout can collapse without breaking.

Key Ideas You Must Use

Bubble’s responsive engine works like Flexbox. Every element needs a meaningful container. A Row shows elements side‑by‑side. A Column stacks elements vertically. Each container controls how child elements resize when the screen shrinks.

• Row container: elements go left-to-right, can wrap when screen gets small.
• Column container: elements go top-to-bottom, often used for mobile layouts.
• Set min width properly: too high = layout breaks; too low = elements squish.
• Use “Align to parent” for centering simple items (like a single button).
• Use responsive conditionals (When current page width < X) to adjust text size or hide/show elements.

Step-by-Step Approach

Start by wrapping each logical area of your page in a container. For example: Header (Row), Page Content (Column), Footer (Row). Inside these, place groups for sections like hero, card lists, or forms.

• In the Responsive tab, set each container to “container layout: row or column” depending on your design.
• Turn on “wrap” for Rows that must stack on mobile.
• Give elements min width around 50–150px depending on their content.
• Let parent groups stretch to fit content unless you want a fixed height.
• Test at breakpoints: 1200px, 992px, 768px, 480px.

Useful Responsive Conditional Example

// Example: shrink text on mobile
When current page width < 420
  → This text's font size = 16

Apply this only when a layout feels tight; don’t overuse conditionals.

Final Practical Tips

• Avoid fixed widths on major containers; use max width instead.
• Images: set to “keep element proportion” so they scale without distortion.
• Repeating groups: For mobile, use 1 column and allow row height to adjust.
• Preview constantly in the responsive mode and drag the width slider.

If you consistently use clean container structure and reasonable min widths, your Bubble app will naturally become mobile responsive without hacks.
