bootstrapnavigation

The navigation bar is a great feature and a prominent feature of a Bootstrap website. Navigation bar is a responsive meta component that serves as the navigation header of an application or website. The navigation bar collapses in mobile viewports and expands horizontally as the available viewport width increases. At its core, the Bootstrap navigation bar includes defining styles for the site name and basic navigation.
The steps to create a default navigation bar are as follows:

Add class .navbar, .navbar-default (black text on white background), navbar-inverse (white text on black background) to the
tag
Add role="navigation" to the above element to help increase accessibility.

Add a header class .navbar-header to the

element, which contains an element with class navbar-brand. This will make the text appear larger.

To add links to the navigation bar, simply add an unordered list with class .nav, .navbar-nav.

The following example demonstrates this:

<!DOCTYPE html> 
<html> 
<head> 
 <title>Bootstrap 实例 - 默认的导航栏</title> 
 <link href="bootstrap.min.css" rel="stylesheet"> 
 <script src="jquery-2.1.4.min.js"></script> 
 <script src="bootstrap.min.js"></script> 
</head> 
<body> 
 
<nav class="navbar navbar-inverse" role="navigation"> 
 <div class="navbar-header"> 
 <a class="navbar-brand" href="#">林炳文在此～</a> 
 </div> 
 <div> 
 <ul class="nav navbar-nav"> 
  <li class="active"><a href="#">导航一</a></li> 
  <li><a href="#">导航二</a></li> 
  <li class="dropdown"> 
  <a href="#" class="dropdown-toggle" data-toggle="dropdown"> 
  下拉菜单 
  <b class="caret"></b> 
  </a> 
  <ul class="dropdown-menu"> 
  <li><a href="#">我是谁呢？</a></li> 
  <li><a href="#">我也不知道</a></li> 
  <li><a href="#">你是谁呢？</a></li> 
  <li class="divider"></li> 
  <li><a href="#">分离的链接</a></li> 
  <li class="divider"></li> 
  <li><a href="#">另一个分离的链接</a></li> 
  </ul> 
  </li> 
 </ul> 
 </div> 
</nav> 
</body> 
</html>

The effect is as follows:

Put it

<nav class="navbar navbar-inverse" role="navigation">

changed to

<nav class="navbar navbar-default" role="navigation">

The effect is as follows:

The above is the code for Bootstrap to implement the default navigation bar effect. I hope it will be helpful to everyone's learning.

From Websites to Apps: The Diverse Applications of JavaScriptApr 22, 2025 am 12:02 AM

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python vs. JavaScript: Use Cases and Applications ComparedApr 21, 2025 am 12:01 AM

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

The Role of C/C in JavaScript Interpreters and CompilersApr 20, 2025 am 12:01 AM

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

JavaScript in Action: Real-World Examples and ProjectsApr 19, 2025 am 12:13 AM

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

JavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AM

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AM

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists

SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
