layout

问题 I'm implementing the CSS3 flexible box layout module as defined by the W3C, which is similar to Mozilla's box model for xul.

Boxes can contain other boxes. Container boxes (parent boxes) are responsible for sizing and positioning the boxes they contain (child boxes). Boxes have orientation which

问题 jsFiddle demo I want the div s to: Wrap their content. Stay in their originally associated line, essentially without wrapping. Basically, the tables are stacking below each other, when they can't stay on screen. I would rather they become hidden off screen. I've tried adding overflow: hidden; to the main layout style. I do not want to fix a width for each div . It needs to fit content in. .layout { -moz-border-radius: 15px; border-radius: 15px; vertical-align: top; display: inline-block; }

问题 According to the documentation, ax.autoscale(tight=True) should If True, set view limits to data limits; With ax.axis('tight') being similar: ‘tight’ Limits set such that all data is shown (sic) And we even see that it works in the screenshots of this question. But no matter what I try, it doesn't seem to work with the following simple example.
