How to center paragraph vertically and horizontally w/ other criteria?

阅读更多关于 How to center paragraph vertically and horizontally w/ other criteria?

问题 So I have been working on my first website, and I'm having lots of fun doing it. However, I have found it very difficult to achieve centering a paragraph (spanning more than one line) vertically and horizontally inside of it's div container. The div has a proportional width (96%), and it is not set by pixels. Also, the paragraph has a set amount of padding (ex: 20px top and bottom). Is there a trick to center vertically and horizontally in this situation? Thanks a bunch! 回答1: See this fiddle

Vertically centred div which increases parent height

阅读更多关于 Vertically centred div which increases parent height

问题 There is a div which has a dynamic content. The height of the parent is 100% of the body and child is unknown. translateY(-50%) technique works good only if a child content height is less than parent.

What's a proper way to set parent div increase the height and add some paddings. .body { height: 300px; background: red; } .parent { height: 100%; position: relative; background: rgb(105, 199, 115); }

Java - how to center vertical column of components?

阅读更多关于 Java - how to center vertical column of components?

问题 It's very simple, what I want to do, but I can't figure out a way to do it. In a JFrame or JPanel, how do you center components vertically? That is, analogous to using the center tag in HTML. The components are in a column and they are all centered. I have tried BoxLayout, with Y_AXIS and PAGE_AXIS, but it aligns the components in a strange way for me. I have tried to use FlowLayout with preferred size set so it wraps around, but it doesn't center it. I'd rather not resort to something
