This lesson

This lesson teaches Containers and max-width—the ideas, syntax, and habits you need before moving on in Bulma.

Bulma offers a lighter component model when Bootstrap feels too heavy or dated.

You will apply Containers and max-width in contexts like: Smaller marketing sites, internal dashboards, and projects that need quick responsive layout with minimal JS.

Read the lesson, edit HTML/CSS in the playground, press Run to preview, then answer the lesson MCQs.

When the previous lesson's MCQs feel easy and you can explain Containers and max-width in your own words.

A container centers content and applies a responsive max-width. Use container is-fluid when edge-to-edge width is intentional (dashboards, full-bleed hero bands).

Container variants

container — responsive max-width that grows with viewport
container is-fluid — always 100% width with horizontal padding
container is-widescreen / is-fullhd — wider caps on large monitors

Wrap page sections in semantic landmarks from HTML structure—main, header, footer—and place container inside them, not instead of them.

Self-check

When would you pick is-fluid over a default container?
What does a container add besides max-width?
