</html> the screenshot rendered according to the above page structure and style is as follows
, .bk1 block inline
I don"t know why a blank space is left at the top of the dispaly: inline-block
the size of this element is also 0 * 0 through the console, and there is no margin.
I don"t know how to explain this
