know that target is the property of a target that is closely related to the browser. So what is rel? Why do many people regard it as an alternative attribute of target? Next, let's get to know Rel. In fact, there is not only oneRELThere is also a corresponding property calledRevThese two attributes mean the relationship between the source document and the target document, and from the target document to the source document. The source document here can be understood as the current document wher

To prevent the client from caching static resources, we need to rename the static resources by MD5 or timestamps every time we update the CSS or JS. Allows the client to re-request the resource instead of fetching it from the cache. The SRC in the HTML template is then modified accordingly. Of course, there is an additional requirement that static resources need to be optimized for themselves (compression merges).Here is the code for my gulpfile.js:varGulp = require ('Gulp'),//Base LibraryClean
Run the Splay command again.This includes interval cutting and reverse operations.For the Splay processing interval [l, r] L-1 to the root and r + 1 to the right child of the root, so that the Left subtree of the right child of the root is [l, r], very sharp. Most of the Splay operations are based on such rotation operations.After the split is rotated, the subtree is removed first, and then transferred to the position to be inserted to connect the subtree.The reverse operation adds a lazy flag t
This article mainly introduces the character-by-character or word-by-word inversion methods of Python strings. This article provides two methods for character-by-character or word-by-word conversion. For more information, see
Purpose
It is interesting to reverse a string by character or word.
Method
Let's first look at the character-by-character inversion. The first method is to set the slice step to-1.
The Code is as follows:
Revchars = astring [:-1]
In [65]: x = 'abc'
In [66]: x [:-1]Out [66

Theoretically, mobile has the best GSM network in the world. In the 4G era, the voice bearer network is sufficient, and the mainstream 4G mo
