这个问题已经遇到好几次,解决起来也熟练了很多。
出现这种问题一般都是html或页面中的某一内部元素宽度超了。
下面总结我遇到的几种情况:
1、某一内部元素width设为100%,然而它还有border的宽度,border的宽度不包含在width中,所以结果超了。
2、span行内元素,由于它是行内元素,不设display:block之类,宽度设定对它没用,当初弄的时候没有意识到这个问题,结果在谷歌浏览器没出现问题,在IE中这个就暴露出来了,严重超出屏幕宽度,后来把span设为display:block;再设下它的宽度,问题就解决了。
PS:对设置width:100%的元素要注意它的border、margin、padding,小心超出屏幕范围。
对于寻找超出屏幕范围的内部元素,我一般先把页面分为几大板块来排除目标(即删掉某板块,看剩余版块是否导致出现水平滚动条,若还是出现,则证明该板块正常,否则该板块为我们寻找的目标板块——“罪魁祸首”),再继续在导致超出的版块中继续询查,直到找到该内部元素为止。
这样的方法挺笨的,希望大家分享自己的经验,交流下怎样能快速找到导致页面内容超出的内部元素,O(∩_∩)O谢谢。

The future trends of HTML are semantics and web components, the future trends of CSS are CSS-in-JS and CSSHoudini, and the future trends of JavaScript are WebAssembly and Serverless. 1. HTML semantics improve accessibility and SEO effects, and Web components improve development efficiency, but attention should be paid to browser compatibility. 2. CSS-in-JS enhances style management flexibility but may increase file size. CSSHoudini allows direct operation of CSS rendering. 3.WebAssembly optimizes browser application performance but has a steep learning curve, and Serverless simplifies development but requires optimization of cold start problems.

The roles of HTML, CSS and JavaScript in web development are: 1. HTML defines the web page structure, 2. CSS controls the web page style, and 3. JavaScript adds dynamic behavior. Together, they build the framework, aesthetics and interactivity of modern websites.

Common errors include unclosed labels and unquoted attribute values, and verification tools are required. 6. Optimization strategies include reducing HTTP requests, compressing HTML, using semantic tags, etc.

HTML is a language used to build web pages, defining web page structure and content through tags and attributes. 1) HTML organizes document structure through tags, such as,. 2) The browser parses HTML to build the DOM and renders the web page. 3) New features of HTML5, such as, enhance multimedia functions. 4) Common errors include unclosed labels and unquoted attribute values. 5) Optimization suggestions include using semantic tags and reducing file size.
