前言 大家使用域名邮箱发送邮件的时候会发现大多数国内邮箱都会直接拉进黑名单删除 甚至连垃圾箱都找不到  这边就给出一个Linux系统一劳永逸的设置方法教程首先打开/etc/hosts的内容一般有如下类似内容：127.0.0.1 localhost.localdomain localhost VM_143_38_centos ::1 localhost.localdomain localhost localhost6 localhost6.localdomain6把以上的内容修改成下面这样就行 如果发现你文件中的代码比较多那也没关系  直接把下面代码复制进去  原先保存的全部去除就好了  当然这边还是要提醒你做好备份 因为随着系统的更新谁也不知道下面的代码适用不适用  至少下列代码在Centos7.6  64位中是可用的 请把下列代码中的qqguoji.cn设置成你域名邮箱的顶级域名即可127.0.0.1 localhost qqguoji.cn VM_143_38_centos ::1 localhost qqguoji.cn localhost6 localhost6.localdomain6本次教程到此结束  如有疑问请在评论席留言 

博主在别人博客看到评论打字特效，觉得好看，网上找了教程发代码跟大家分享，这个效果原本是Atom编辑器上的一个插件，现在只要在网页上引用JS脚本，我们的网站也能拥有如此有逼格的效果。教程如下：先在你网站根目录建立一个文件，名称随便只要记得住就行，后缀名为JS。然后用编辑器打开（建议不要用记事本），然后将下列代码复制过去。以下是javascript代码：(function webpackUniversalModuleDefinition(root, factory) { if(typeof exports === 'object' && typeof module === 'object') module.exports = factory(); else if(typeof define === 'function' && define.amd) define([], factory); else if(typeof exports === 'object') exports["POWERMODE"] = factory(); else root["POWERMODE"] = factory(); })(this, function() { return (function(modules) { // webpackBootstrap var installedModules = {}; function __webpack_require__(moduleId) { if(installedModules[moduleId]) return installedModules[moduleId].exports; var module = installedModules[moduleId] = { exports: {}, id: moduleId, loaded: false }; modules[moduleId].call(module.exports, module, module.exports, __webpack_require__); module.loaded = true; return module.exports; } __webpack_require__.m = modules; __webpack_require__.c = installedModules; __webpack_require__.p = ""; return __webpack_require__(0); }) ([ function(module, exports, __webpack_require__) { 'use strict'; var canvas = document.createElement('canvas'); canvas.width = window.innerWidth; canvas.height = window.innerHeight; canvas.style.cssText = 'position:fixed;top:0;left:0;pointer-events:none;z-index:999999'; window.addEventListener('resize', function () { canvas.width = window.innerWidth; canvas.height = window.innerHeight; }); document.body.appendChild(canvas); var context = canvas.getContext('2d'); var particles = []; var particlePointer = 0; POWERMODE.shake = true; function getRandom(min, max) { return Math.random() * (max - min) + min; } function getColor(el) { if (POWERMODE.colorful) { var u = getRandom(0, 360); return 'hsla(' + getRandom(u - 10, u + 10) + ', 100%, ' + getRandom(50, 80) + '%, ' + 1 + ')'; } else { return window.getComputedStyle(el).color; } } function getCaret() { var el = document.activeElement; var bcr; if (el.tagName === 'TEXTAREA' || (el.tagName === 'INPUT' && el.getAttribute('type') === 'text')) { var offset = __webpack_require__(1)(el, el.selectionStart); bcr = el.getBoundingClientRect(); return { x: offset.left + bcr.left, y: offset.top + bcr.top, color: getColor(el) }; } var selection = window.getSelection(); if (selection.rangeCount) { var range = selection.getRangeAt(0); var startNode = range.startContainer; if (startNode.nodeType === document.TEXT_NODE) { startNode = startNode.parentNode; } bcr = range.getBoundingClientRect(); return { x: bcr.left, y: bcr.top, color: getColor(startNode) }; } return { x: 0, y: 0, color: 'transparent' }; } function createParticle(x, y, color) { return { x: x, y: y, alpha: 1, color: color, velocity: { x: -1 + Math.random() * 2, y: -3.5 + Math.random() * 2 } }; } function POWERMODE() { { var caret = getCaret(); var numParticles = 5 + Math.round(Math.random() * 10); while (numParticles--) { particles[particlePointer] = createParticle(caret.x, caret.y, caret.color); particlePointer = (particlePointer + 1) % 500; } } { if (POWERMODE.shake) { var intensity = 1 + 2 * Math.random(); var x = intensity * (Math.random() > 0.5 ? -1 : 1); var y = intensity * (Math.random() > 0.5 ? -1 : 1); document.body.style.marginLeft = x + 'px'; document.body.style.marginTop = y + 'px'; setTimeout(function() { document.body.style.marginLeft = ''; document.body.style.marginTop = ''; }, 75); } } }; POWERMODE.colorful = false; function loop() { requestAnimationFrame(loop); context.clearRect(0, 0, canvas.width, canvas.height); for (var i = 0; i < particles.length; ++i) { var particle = particles[i]; if (particle.alpha <= 0.1) continue; particle.velocity.y += 0.075; particle.x += particle.velocity.x; particle.y += particle.velocity.y; particle.alpha *= 0.96; context.globalAlpha = particle.alpha; context.fillStyle = particle.color; context.fillRect( Math.round(particle.x - 1.5), Math.round(particle.y - 1.5), 3, 3 ); } } requestAnimationFrame(loop); module.exports = POWERMODE; }, function(module, exports) { (function () { var properties = [ 'direction', 'boxSizing', 'width', 'height', 'overflowX', 'overflowY', 'borderTopWidth', 'borderRightWidth', 'borderBottomWidth', 'borderLeftWidth', 'borderStyle', 'paddingTop', 'paddingRight', 'paddingBottom', 'paddingLeft', 'fontStyle', 'fontVariant', 'fontWeight', 'fontStretch', 'fontSize', 'fontSizeAdjust', 'lineHeight', 'fontFamily', 'textAlign', 'textTransform', 'textIndent', 'textDecoration', 'letterSpacing', 'wordSpacing', 'tabSize', 'MozTabSize' ]; var isFirefox = window.mozInnerScreenX != null; function getCaretCoordinates(element, position, options) { var debug = options && options.debug || false; if (debug) { var el = document.querySelector('#input-textarea-caret-position-mirror-div'); if ( el ) { el.parentNode.removeChild(el); } } var div = document.createElement('div'); div.id = 'input-textarea-caret-position-mirror-div'; document.body.appendChild(div); var style = div.style; var computed = window.getComputedStyle? getComputedStyle(element) : element.currentStyle; // currentStyle for IE < 9 style.whiteSpace = 'pre-wrap'; if (element.nodeName !== 'INPUT') style.wordWrap = 'break-word'; style.position = 'absolute'; if (!debug) style.visibility = 'hidden'; properties.forEach(function (prop) { style[prop] = computed[prop]; }); if (isFirefox) { if (element.scrollHeight > parseInt(computed.height)) style.overflowY = 'scroll'; } else { style.overflow = 'hidden'; } div.textContent = element.value.substring(0, position); if (element.nodeName === 'INPUT') div.textContent = div.textContent.replace(/\s/g, "\u00a0"); var span = document.createElement('span'); span.textContent = element.value.substring(position) || '.'; // || because a completely empty faux span doesn't render at all div.appendChild(span); var coordinates = { top: span.offsetTop + parseInt(computed['borderTopWidth']), left: span.offsetLeft + parseInt(computed['borderLeftWidth']) }; if (debug) { span.style.backgroundColor = '#aaa'; } else { document.body.removeChild(div); } return coordinates; } if (typeof module != "undefined" && typeof module.exports != "undefined") { module.exports = getCaretCoordinates; } else { window.getCaretCoordinates = getCaretCoordinates; } }()); } ]) }); ;然后在模板的header.php、footer.php、网站后台 - 设置 - 首页底部信息 其中任意一个地方添加以下代码就可以了.<script type="text/javascript" src="这里填写你刚建立的JS的路径/你输入的名称.js"></script> <script>POWERMODE.colorful = true;POWERMODE.shake = false;document.body.addEventListener('input', POWERMODE);</script> 注意，本站用的emlog程序在header.php添加后无效 请使用emlog的站长把最后两行代码置入footer.php文件或后台底部设置中

一、效果图二、代码部署注意将相应的代码文件放入到相应的css和js文件中1、在模板目录的headre.php文件中的<head></head>中间添加如下下代码~<link rel="stylesheet" href="<?php echo TEMPLATE_URL; ?>css/sweetalert.css" type='text/css' /> <script src="<?php echo TEMPLATE_URL; ?>js/sweetalert.min.js"></script>2、在footer.php文件中的</body>前面加入以下代码~<script>document.body.oncopy = function() {swal("复制成功！", "若要转载请务必保留原文链接，申明来源，谢谢合作！","success");};</script>
