I see this is probably a noob question, but it truly confuses me.
I’m reading documents from the Google Material Design, along with some of its implementations in css. The specification is written in Android’s
dp, while css codes uses
pxas a length unit.
What confuses me is that the css implementations often uses the exact value from specification, for example, a toast should have:
Single-line snackbar height: 48 dp tall
Minimum width: 288 dp
2 dp rounded corner
min-height: 48px; min-width: 288px; ... border-radius: 2px;
In my current understanding, an Android
DPis generally displayed at the size of one pixel on a 160dpi screen, while the CSS
pxis defined as a visual angle. So does a
pxhappens to be the same as a
dpwhen seeing in some distance? If so, is that a common pattern to use
dpin css, or did I completely misunderstand the CSS code?
I know nothing about Android development before, and not a designer. Thanks for any help.
I think the accepted is wrong. The css px is actually Device Independent Pixel(dip), and it is a common pattern to use px as dp in css.
