How do I remove the space between div and top of page?

阅读更多关于 How do I remove the space between div and top of page?

问题 This has probably been asked a million and one times, but I would appreciate it if someone could explain the behavior of the divs to me.. I have a container div which I am aligning in the center of the page, which has a gap between the top and the top of the page. I want it to be flush against the top of the page. I am assuming that there is some sort of margin or padding that I need to remove but I can't think what it could be. Even with nothing in the div there is still a gap. <body> <div

Why does XAML Margin not follow CSS norm?

阅读更多关于 Why does XAML Margin not follow CSS norm?

问题 In CSS the margin order is: top right bottom left In XAML the margin order is: left top right bottom Is there a reason why the WPF team didn't align this to the CSS norm? 回答1: I imagine this is because margins in WinForms were declared as left, top, right, bottom. They likely thought it would be more likely to have WinForms developers move on to WPF rather than those from the web. For reference you can check the constructor for the Padding structure on MSDN (the type used for the Margin

web前端入门到实战：css3动画 Transition

阅读更多关于 web前端入门到实战：css3动画 Transition

CSS transitions 提供了一种在更改CSS属性时控制动画速度的方法。其可以让属性变化成为一个持续一段时间的过程，而不是立即生效的。比如，将一个元素的颜色从白色改为黑色，通常这个改变是立即生效的，使用 CSS transitions 后该元素的颜色将逐渐从白色变为黑色，按照一定的曲线速率变化。这个过程可以自定义。 CSS transitions 可以决定哪些属性发生动画效果 (明确地列出这些属性)，何时开始 (设置 delay），持续多久 (设置 duration) 以及如何动画 (定义 timing funtion ，比如匀速地或先快后慢)。可动画属性的列表是： -moz-outline-radius -moz-outline-radius-bottomleft -moz-outline-radius-bottomright -moz-outline-radius-topleft -moz-outline-radius-topright -webkit-text-fill-color -webkit-text-stroke -webkit-text-stroke-color all backdrop-filter background background-color background-position background-size border border
