我刚刚关注了Sass教程.由于某种原因虽然Sass文件没有正确生成css.终端说css无效,但我很确定它不是.我已经尝试过更改它以防万一有问题...

我做错了什么？

Sass版本:Sass 3.1.10

错误信息:

error sass/test.sass (Line 3: Invalid CSS after "80%": 
expected expression (e.g. 1px, bold), was ";")

.sass文件内容:

/* style.scss */
#navbar {
  width: 80%;
  height: 23px;
}

I have a simple python script, that has some functions that run in a loop (I'm taking sensor readings).

while True:
    print "Doing a function"

If the keyboard is pressed I'd like to print "key pressed".

What's the simplest way of doing this in Python? I've searched high and low. I've found out how to do it with pygame, but I'd rather do it without. If I do have to use pygame is it possible to not have a separate …

我正在尝试使用http://snapsvg.io/为序列中的几个对象设置动画.

我希望第一个对象移动,一旦完成第二个移动对象等.

而是使用以下代码同时动画.

    var s = Snap("#svg");

    var triangle = s.path("M200 200,L600,500 L200,500 L200,200");

    var triangleClone = triangle.clone();
    triangleClone.animate({'transform' : 'r90,200,200 T400,300'}, 1000);

    var triangleClone2 = triangle.clone();
    triangleClone2.animate({'transform' : 'r180,200,200 T100,700'},1000);

    var triangleClone3 = triangle.clone();
    triangleClone3.animate({'transform' : 'r270,200,200 T-300,400'},1000);

您需要采取什么方法来控制动画的动画？似乎没有一个回调挂钩.

我想点击/查看一个html元素,找出哪个css规则负责哪个格式属性.

即我想知道字体来自身体{}来自h {}的颜色和来自#headercontainer的填充

有办法做到这一点吗？

我已经尝试过firebug和cssedit(两者都非常酷)但是看不到你在哪里找到继承.

想要做到这一点似乎是一件有用的事情必须有办法!

谢谢.
