昨天切页面时,进行布局时,想改变以下方法换换口味,所以就抛弃了float方法,采用了display:inline-block方法,没想到却随之而来的带来了一个想不通的问题,那就是空白。废话不多说,上代码。
<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>inline-block的空白符</title><style type="text/css"> li{ width:50px; height:20px; background-color:#C90; display:inline-block;}</style></head> <body> <ul class="box"> <li>li</li> <li>li</li> <li>li</li> <li>li</li> </ul></body></html>
效果如上图所示,每个li之间都会有空格,这影响到我们对页面的布局。
一、造成的原因
inline-block水平呈现的元素之间,如果有换行或空格分隔,那么元素之间会有间距。
二、解决的方法
1、去除元素间的空白或者换行
<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>inline-block的空白符</title><style type="text/css"> li{ width:50px; height:20px; background-color:#C90; display:inline-block;}</style></head> <body> <ul class="box"> <strong> <li>li</li><li>li</li><li>li</li><li>li</li></strong> </ul></body></html><br /><br /><br />
<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>inline-block的空白符</title><style type="text/css"> li{ width:50px; height:20px; background-color:#C90; display:inline-block;}</style></head> <body> <ul class="box"> <li> li</li><li> li</li><li> li</li><li> li</li> </ul></body></html> <br />
<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>inline-block的空白符</title><style type="text/css"> li{ width:50px; height:20px; background-color:#C90; display:inline-block;}</style></head> <body> <ul class="box"> <li>li</li ><li>li</li ><li>li</li ><li>li</li> </ul></body></html><br /><br />
<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>inline-block的空白符</title><style type="text/css"> li{ width:50px; height:20px; background-color:#C90; display:inline-block;}</style></head> <body> <ul class="box"> <li>li</li><!-- --><li>li</li><!-- --><li>li</li><!-- --><li>li</li> </ul></body></html><br /><br /><br />
2、利用margin负外边距
<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>inline-block的空白符</title><style type="text/css"> li{ width:50px; height:20px; background-color:#C90; display:inline-block; margin-right:-8px;}//不过这个间距是根据字体的大小来调的,不具有普适性</style></head> <body> <ul class="box"> <li>li</li> <li>li</li> <li>li</li> <li>li</li> </ul></body></html>
3、因为空白字符也是字符,所以可以设置父元素的font-size:0,子元素重新定义font-size大小;但是这种方法在Safari中是无效的。
<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>inline-block的空白符</title><style type="text/css"> .box{ font-size:0;} li{ width:50px; height:20px; background-color:#C90; display:inline-block; font-size:12px;}</style></head> <body> <ul class="box"> <li>li</li> <li>li</li> <li>li</li> <li>li</li> </ul></body></html>
4、使用letter-spacing
<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>inline-block的空白符</title><style type="text/css"> .box{ letter-spacing:-8px;} li{ width:50px; height:20px; background-color:#C90; display:inline-block; letter-spacing:normal;}</style></head> <body> <ul class="box"> <li>li</li> <li>li</li> <li>li</li> <li>li</li> </ul></body></html><br /><br />//Opera浏览器下问题:最小间距1像素,然后,letter-spacing再小就还原了
5、使用word-spacing
<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>inline-block的空白符</title><style type="text/css"> .box{ word-spacing:-8px;} li{ width:50px; height:20px; background-color:#C90; display:inline-block; word-spacing:normal;}</style></head> <body> <ul class="box"> <li>li</li> <li>li</li> <li>li</li> <li>li</li> </ul></body></html>

Boolean attributes are special attributes in HTML that are activated without a value. 1. The Boolean attribute controls the behavior of the element by whether it exists or not, such as disabled disable the input box. 2.Their working principle is to change element behavior according to the existence of attributes when the browser parses. 3. The basic usage is to directly add attributes, and the advanced usage can be dynamically controlled through JavaScript. 4. Common mistakes are mistakenly thinking that values need to be set, and the correct writing method should be concise. 5. The best practice is to keep the code concise and use Boolean properties reasonably to optimize web page performance and user experience.

HTML code can be cleaner with online validators, integrated tools and automated processes. 1) Use W3CMarkupValidationService to verify HTML code online. 2) Install and configure HTMLHint extension in VisualStudioCode for real-time verification. 3) Use HTMLTidy to automatically verify and clean HTML files in the construction process.

HTML, CSS and JavaScript are the core technologies for building modern web pages: 1. HTML defines the web page structure, 2. CSS is responsible for the appearance of the web page, 3. JavaScript provides web page dynamics and interactivity, and they work together to create a website with a good user experience.

The function of HTML is to define the structure and content of a web page, and its purpose is to provide a standardized way to display information. 1) HTML organizes various parts of the web page through tags and attributes, such as titles and paragraphs. 2) It supports the separation of content and performance and improves maintenance efficiency. 3) HTML is extensible, allowing custom tags to enhance SEO.

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.

The future of HTML is full of infinite possibilities. 1) New features and standards will include more semantic tags and the popularity of WebComponents. 2) The web design trend will continue to develop towards responsive and accessible design. 3) Performance optimization will improve the user experience through responsive image loading and lazy loading technologies.

The roles of HTML, CSS and JavaScript in web development are: HTML is responsible for content structure, CSS is responsible for style, and JavaScript is responsible for dynamic behavior. 1. HTML defines the web page structure and content through tags to ensure semantics. 2. CSS controls the web page style through selectors and attributes to make it beautiful and easy to read. 3. JavaScript controls web page behavior through scripts to achieve dynamic and interactive functions.
