A problem occurs after self adjustments of the header - height. If the header is higher than 100px a part of the content is hidden.

All of the below use only a single HTML element. Any kind of CSS goes, as long as it's supported in at least one browser. (下面的所有内容只使用一个HTML元素。任何一种CSS都可以,只要它在至少一个浏览器中支持。) Square (正方形) /*--> */ /*--> */ #square { width: 100px; height: 100px; background: red; } Rectangle (长方形) /*--> */ /*--> */ #rectangle { width: 200px; height: 100px; background: red; } Circle (圆形) /*--> */ /*--> */ #circle { width: 100px; height: 100px; background: red; -moz-border-radius: 50px; -webkit-border-radius: 50px; border-radius: 50px; } /* Cleaner, but slightly less support: use "50%" as value */ 半圆形(Semicircle) 扇形

CSS能够生成各种形状。正方形和矩形很容易,因为它们是 web 的自然形状。添加宽度和高度,就得到了所需的精确大小的矩形。添加边框半径,你就可以把这个形状变成圆形,足够多的边框半径,你就可以把这些矩形变成圆形和椭圆形。 我们还可以使用 CSS 伪元素中的 ::before 和 ::after,这为我们提供了向原始元素添加另外两个形状的可能性。通过巧妙地使用定位、转换和许多其他技巧,我们可以只用一个 HTML 元素在 CSS 中创建许多形状。 虽然我们现在大都使用字体图标或者svg图片,似乎使用 CSS 来做图标意义不是很大,但怎么实现这些图标用到的一些技巧及思路是很值得我们的学习。 1.正方形 #square { width: 100px; height: 100px; background: red; } 2.长方形 #rectangle { width: 200px; height: 100px; background: red; } 3.圆形 #circle { width: 100px; height: 100px; background: red; border-radius: 50% } 4.椭圆形 #oval { width: 200px; height: 100px; background: red; border-radius: 100px / 50px; } 5

JQuery - Copy dimensions and absolute position of element

问题 I'm trying to copy a element's dimensions and the position(relative to the document) onto another element. Ex: var SelectedElement = $("div#MyTargetElement"); // The CopiedButEmpty element is a div with absolute position that is meant to hover/float above the selected element. $("div#CopiedButEmpty").css("width", SelectedElement.width()).css("height", SelectedElement.height()) .css("left", SelectedElement.offset().left).css("top", SelectedElement.offset().top) .css("marginTop",

问题 I found a lot of articles about this subject but none off it will work for me, i want to make a footer that's on the bottom of the screen when the content isn't large enough, but when the content is longer than the screen that my footer stays under the content and doesn't stick at the bottom of the screen. Thanks in advance! 回答1: Here is just another example how to do it, works fine in all browsers AFAIK. http://peterned.home.xs4all.nl/examples/csslayout1.html Edit: I am not the author, just

弹力 介绍 弹簧的弹力可以根据胡克定律计算得到,胡克定律以英国物理学家罗伯特·胡克命名,他在1660年发明了这个公式。胡克最初是用拉丁文描述这个公式的——“Ut tensio,sic vis”, 这句话的意思是“力如伸长(那样变化)”。我们可以这么理解它:弹簧的弹力与弹簧的伸长量成正比。 先用胡克定律计算弹力的大小。我们需要知道k和x的值:k很简单,它只是一个常量,我们可以随意选择一个数。 float k = 0.1 ; x可能会更复杂,我们需要知道“当前长度和静止长度的差”。可以用restLength表示静止长度, PVector dir = PVector . sub ( bob , anchor ) ; 由枢轴点指向摆锤的向量,它告诉我们弹簧的当前长度 float currentLength = dir . mag ( ) ; float x = restLength - currentLength ; 方向计算 float k = 0.1 ; 按照胡克定律计算得到的弹力 PVector force = PVector . sub ( bob , anchor ) ; float currentLength = dir . mag ( ) ; float x = restLength - currentLength ; force . normalize ( ) ;
