html&css的使用过程中,我们经常会遇到很多文字对齐问题。下面我要介绍一个有丁点难的文字对齐问题。
实现效果如下图所示。
两行长度不定的文字,要让它们总体水平居中,然后,这两行字要左对齐,如下图所示。
听起来好像挺简单,然而实现起来却。。。。。。
错误做法一:
用一个大块div包住两个div,在大div中设置"text-align:center; ",在小div中设置"text-align:left; "
结果如下图所示。
因为div会占据一整行,而不能随内容大小自动调节宽度,如果要对大div设置width,这也不好控制,因为万一文段长度改变,那么还是无法实现居中。
错误做法二:
于是我把小div改成span,因为span是行内元素,能随span内的文段宽度来调节自身宽度。结果如下图所示。
因为span自动调节自身宽度(即span宽度等于文段长度),所以"text-align:left; "对它不起作用。
正确做法:
既然块级元素和行内元素都无法实现该效果,那能否折中采取介于它们之间的元素。
对,就是设置"display:inline-block;"。
效果图如下:
思路:在一个大div中放置一个小div,小div中包含2个span文段。大div设置"text-align:center; ",让小div居中; 小div设置"display:inline-block;",这样小div就能有行内元素的特性,会根据内容自动调节自己的宽度,再设置"text-align:left; ",让其中的元素左对齐,这样就搞定了。
Tip:小div中的span元素可替换为div等块级元素,小div可替换为span等行内元素。
html代码如下:
<div id="container"> <div id="child-container"> <span class="text">请尽快付款以保证商家能及时提供服务</span><br/> <span class="text">未支付订单将在半个小时后关闭</span> </div></div>
css代码如下:
1 *{ 2 margin: 0; 3 padding: 0; 4 } 5 #container { 6 text-align: center; 7 background-color: #DBEDFD; //这三句只是为了美观,请忽略。。。 8 height: 40px; 9 padding: 15px 0;10 }11 #child-container {12 text-align: left;13 display: inline-block;14 }

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.
