From docs:
On mobile and tablet, the container will have a margin of 20px on both the left and right sides.
This doesn't seem to occur and doesn't seem to be included in elements/_other.sass
I'll gladly submit a pull request, but not sure if docs are correct, or if source is correct.
Also, on widescreen (>1180px) its max-width is 1200px, and this is not explicitly said in the documentation, that does only says it is at most 960px on >950px screen.
Any update on this?
I just started with bulma. Should i add side margins for container?
@jgthms are you able to provide an update -- i have no problem submitting a pull request.
Just discovered this too. The stylesheet on the documentation is slightly different to the one downloaded. Docs has a max-width on the container but neither the docs nor the download have a margin on the container.
Additionally, if you put a .container inside a .section as per in the docs, the container is offset from the left inside the section's padding, but falls off the page on the right because it has a fixed width. Screenshot taken with browser width at 1004px width. Can be replicated by putting the documentation container inside a .section.

Updates?
+1
can confirm, the margins seem to be missing on mobile / tablet
Also having this issue.
I used to believe this was an issue, but after becoming more familiar with Bulma I believe you're supposed to use sections, which have padding built into them: http://bulma.io/documentation/layout/section/
<body>
<section class="section">
<div class="container">
<h1 class="title">Section</h1>
<h2 class="subtitle">
A simple container to divide your page into <strong>sections</strong>, like the one you're currently reading
</h2>
</div>
</section>
</body>
@ryanio that is what I end up doing. my main reason for opening the issue was that the docs doesn't seem to match the source. I'd be happy to submit a pull request, but not sure if it is the docs or the source that needs to be updated.
In the case of this issue added with the #1017 you have no margin on the menu in the only way it works fine.
EDIT: added image.

Any updates?
There is a $gap variable now.
How would you use $gap variable?
How would you use $gap variable?
Using SCSS.
@jgthms but there is no possibility to add it on mobile / tablet?
