问题 I'm sending requests from the localhost to third party server to get data using REST API. Backend uses cookies ("JSESSIONID") to understand either send data or not. All works fine in Chrome, and I can see Cookies in the Application tab of the Chrome browser, with some data. But this specific key ("JSESSIONID") is not set as a value. Meanwhile in Safari Cookies tab does not contain any value, but I can see this line in Response: Set-Cookie: JSESSIONID

3 月,跳不动了?>>> 在写手机网页时,对于像素的问题会非常困惑,初学者很多时候会因为那么一个小点的问题解决不了,或者无法理解透彻就放弃了学习。 我在学习写手机网页时也困惑了许久,出现过下面的问题: 图片素材按照640px*330px像素设计,放入img,并且img设置了铺满全屏style: .img{ width:100%; height:16.5rem; ] PS:我将html设置了 html{ font-size:20px; } 所以按照rem的算法,img的高度应该是330px/20px=16.5rem(rem怎么用?下片文章会用我们外行的白话来说明) 这时候在chrome谷歌浏览器中调试效果,发现图片宽度变成了980px,然后各种算rem算不对,实在没想明白,为啥自己的图片明明是640px宽,怎么到了浏览器里被放大到980了, 后来翻阅了网上各大神的文章,发现 移动设备上的浏览器都会把自己默认的viewport设为980px或1024px 所以这个时候需要在<head>里面加入下面的一段代码: <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0"> 该meta标签的作用是让当前viewport的宽度等于设备的宽度

Why do web browsers don't apply the CSS :active state on activation by enter key?

江枫思渺然 提交于 2020-03-23 07:04:29
问题 Most web browsers provide keyboard shortcuts to interact with the DOM. e.g.: Tab shifts the focus to the next focus-able element Alt + Tab shifts the focus to the previous focus-able element Enter activates the currently focused element What I have now figured out is that many popular browsers (Firefox, Chrome, Safari, Internet Explorer) don't apply the CSS :active pseudo-class if an element gets activated by pressing the Enter key. Why is this so? I think it is misleading because it looks

浏览器渲染机制

3 月,跳不动了?>>> 之前大概知道个流程,现在梳理下 印象深刻。 要了解浏览器渲染页面的过程,首先得知道一个名词——关键渲染路径。关键渲染路径是指浏览器从最初接收 请求来 的HTML、CSS、javascript等资源,然后解析、构建树、渲染布局、绘制,最后呈现给客户能看到的界面这整个过程。 用户看到页面实际上可以分为两个阶段:页面内容加载完成和页面资源加载完成,分别对应于 DOMContentLoaded 和 Load 。 DOMContentLoaded 事件触发时,仅当DOM加载完成,不包括样式表,图片等 load 事件触发时,页面上所有的DOM,样式表,脚本,图片都已加载完成, load事件时间上比$(document).ready()还后面 浏览器渲染的过程主要包括以下五步: 浏览器将获取的HTML文档解析成DOM树。 处理CSS标记,构成层叠样式表模型CSSOM(CSS Object Model)。 将DOM和CSSOM合并为渲染树( rendering tree )将会被创建,代表一系列将被渲染的对象。 渲染树的每个元素包含的内容都是计算过的,它被称之为布局 layout 。浏览器使用一种流式处理的方法,只需要一次绘制操作就可以布局所有的元素。 将渲染树的各个节点绘制到屏幕上,这一步被称为绘制 painting 。 需要注意的是,以上五个步骤并不一定一次性顺序完成

如何修复Safari在Mac上运行缓慢的问题?

某厂面试归来,发现自己落伍了!>>> 为什么Safari在Mac上运行如此缓慢?有时,加载网页似乎要花很多时间,这实在令人沮丧。而且您将无法在页面之间来回切换。今天就来讲一讲如何修复Safari在Mac上运行缓慢的问题? 1:过度工作的缓存和历史记录 与所有其他浏览器一样,Safari会自动将有关您访问的每个网站的信息存储为浏览历史记录。这些网站的元素(例如图像和html文件)将保存到缓存中,以便下次加载页面时更快,这给浏览器增加了负担。过度工作的缓存和历史记录可能是Safari变慢的最大“罪魁祸首”。因此,请尝试摆脱固定重量,然后查看Safari是否仍然很慢。以下是清除缓存中数据的方法,以便Safari可以更快地运行。 在Safari中清理历史记录 1.打开Safari 2.在菜单栏中查找历史记录(或单击Safari,然后选择清除历史记录) 3.单击底部的清除历史记录 4.选择时间范围,然后单击清除历史记录按钮。 清理Safari中的缓存 1.打开Safari 2.在菜单栏中找到首选项 3.转到高级选项卡 4.在菜单栏中选中“显示显影菜单” 5.单击菜单栏中的“开发” 6.选择清空缓存 您也可以手动清除清除Cache.db文件 1.打开查找器 2.单击底部的“转到并转到文件夹” 3.通过“~/ Library / Caches / com.apple.Safari / Cache
