shorthand

问题 I am learning C#, and am learning about making fields private to the class, and using Getters and Setters to expose Methods instead of field values. Are the get; set; in Method 1 and Method 2 equivalent? e.g. is one a shorthand of the other? class Student { // Instance fields private string name; private int mark; // Method 1 public string Name { get; set; } // Method 2 public int Mark { get { return mark; } set { mark = value; } } } Finally, would Method 2 be used when you want to for

问题 the question is as follows: if you take a look at any site using addthis (the share button)... once you float over the addthis button, and all of the required assets load take a look at the body of the document using firebug or chrome inspector (not the source, the actual document that is sitting on your screen... the object inspector). you will notice that the additional assets loaded automatically by addthis look something like this: <script type="text/javascript" src="//s7.addthis.com

问题 If I have: background:#A2A2A2 url('./images/img.png') repeat-x left bottom; and then I use: background:#000000; /* not to confuse with 'background-color' */ Do background-image , background-repeat and background-position are lost? 回答1: background-image , background-repeat and background-position (among other things) will be implicitly set to their default values when you leave them out in the shorthand property. It's just how a shorthand property works (for the most part). The computed

问题 Is this border-radius:10px 10px 0 0; A shortend version that will work with all browsers that recognise it to this: border-top-left-radius:10px; border-top-right-radius:10px; 回答1: Yes, it's better the first approach because it's shorter and waste less bandwith. 回答2: Yes they are identical just like there is padding-left there is border-top-left-radius. 回答3: If you really want the confidence of knowing that it will work on all the browsers that can support it, you should be using Compass. 来源：

问题 I understand that background is the shorthand property - what will the value 0 do to all of the properties and is it valid CSS? selector {background:0;} 回答1: background:0 is valid css and gets compiled into: background-image: initial; background-position-x: 0px; background-position-y: 50%; background-size: initial; background-repeat-x: initial; background-repeat-y: initial; background-attachment: initial; background-origin: initial; background-clip: initial; background-color: initial; 回答2:

问题 Hi, what is the shorthand for border when borders have different width? I tried this: border:1px solid black, 2px solid black, 3px solid black, 4px solid black; and this: border:1px 2px 3px 4px, solid, solid, solid, solid, black, black, black, black; but none of them work. Thank you. 回答1: Use border: solid black; border-width: 1px 2px 3px 4px; 来源： https://stackoverflow.com/questions/37437141/css-border-shorthand-when-each-border-has-a-different-width

问题 There are shorthand operators for the basic arithmetic operators, such as: x = x+2; x += 2; or y = y*2; y *= 2; However, I was wondering if there was any such operator that could simply invert the value of a boolean. For example, assuming z = true , is there any shorter equivalent to: z = !z; I know it can't be just !z , because then it would just return the opposite value of z , but it wouldn't change its value. I know I'm kind of lazy, but I use this a lot in my code and am trying to

问题 I was researching some information on the topic of trial division, and I came across this symbol in Python: //= I got this from here where the code in the example says: n //= p I can't tell what this is supposed to mean, and my research continues to bring poor results in terms of webpages. 回答1: // is integer division and the n //= p syntax is short for n = n // p except the value n is modified directly if it supports this. 回答2: When you see an operator followed by an = , that is performing

问题 I'd like to incorporate whatever shorthand techniques there are in my regular coding habits and also be able to read them when I see them in compacted code. Anybody know of a reference page or documentation that outlines techniques? Edit: I had previously mentioned minifiers and it is now clear to me that minifying and efficient JS-typing techniques are two almost-totally-separate concepts. 回答1: Updated with ECMAScript 2015 (ES6) goodies. See at the bottom. The most common conditional
