The MVC Model Controller pattern MVC pattern (model-view-controller) is a software architecture pattern in software project. The software system is divided into three basic parts: model, view, and controller.

element, 1em = 14px If the element's font-size is 14px, and 1em = 18px If the font-size is 18px. The following code:P{font-size:12px;text-indent:2em;}The code above is the ability to indent the first line of a paragraph by 24px (that is, the distance of two font sizes).A special case is noted below:However, when Font-size is set to EM, the criteria for this calculation are based on the font-size of the parent element of P. The following code:Html:Css:P{font-size:14px}span{font-size:0.8em;}As a
point, we just need to encapsulate its functional code for later invocation. This is the model layer in the MVC pattern. For example:We create a new Java class called tools with the following code:/** * Tool class * */public class Tools {public static void OutPut (Object obj) { System.out.println (obj);} }At this point, if we want to output a data, directly call the Tools.output (parameter) method to output data.4 , using St

Three, omit curly braces {}
if (foo) return bar (); else something (); ==> {if (foo) return bar (); something ()}
You and I are familiar with this type of writing, but I suggest doing it in code optimization, or handing it over to Uglifyjs to help you solve it. After all, less than a curly brace, the code is not very readable.
Writing here, I think of the way in which the father of jquery is getting HTML element attributes
The general use of CSS to set font properties is to do this:
Example Source Code [www.52css.com] font-weight:bold;
Font-style:italic;
Font-varient:small-caps;
Font-size:1em;
Line-height:1.5em;
Font-family:verdana,sans-serif;
But you can also write them all in one line:
Example Source Code [www.52css.com] font:bold italic small-caps 1em/1.5em Verdana,sans-serif;
That's good. There is only one point to be reminded: this shorthand method only works i

Using the Free Pen tool, we can draw the path curve as freely as drawing on the canvas with a brush. You do not have to define the location of the anchor, because it is automatically added, after the drawing is done to further adjust. The number of automatically added anchor points is determined by the curve fitting and parameters in the Free Pen tool options Bar, the smaller the parameter value the larger

The above wording is equivalent to

That is, the Exec method can be used in the Firefox/safari/chrome/opera browser to remove "exec" using the "regular direct amount + ()" method.
