Use jQuery to dynamically change web page styles
In web design, style is a very important part. You can enhance user experience and page design by changing styles. Effect. Using JavaScript libraries like jQuery can help us dynamically change the style of web pages, making the pages more lively and interesting. This article will introduce how to use jQuery to dynamically change web page styles and provide specific code examples.
First, we need to introduce the jQuery library into the web page, which can be introduced through a CDN link or by downloading a local file. Add the following code to the header of the HTML file:
<script src="https://cdn.jsdelivr.net/npm/jquery@3.6.0/dist/jquery.min.js"></script>
Next, we can write some jQuery code to dynamically change the web page style. Here is a simple example of changing the text color when the button is clicked:
jQuery动态改变样式示例 <script src="https://cdn.jsdelivr.net/npm/jquery@3.6.0/dist/jquery.min.js"></script>这是一段文本
<script> $(document).ready(function(){ $('#changeColorBtn').click(function(){ $('.text').css('color', 'red'); }); }); </script>
In the above example, clicking the button will change the text color to red. We used jQuery's css()
method to modify the style of the element.
In addition to changing colors, we can also dynamically change other styles, such as background color, font size, element position, etc. Here is an example of changing the background color and font size:
jQuery动态改变样式示例 <script src="https://cdn.jsdelivr.net/npm/jquery@3.6.0/dist/jquery.min.js"></script>这是一段文本
<script> $(document).ready(function(){ $('#changeStyleBtn').click(function(){ $('.text').css({ 'background-color': 'lightblue', 'font-size': '24px' }); }); }); </script>
In this example, clicking the button will change the text background color to light blue and the font size to 24px.
In general, by using jQuery, we can easily achieve dynamic changes in web page styles and improve user experience and page design effects. Of course, there are more and richer style changing effects waiting for us to explore and practice. I hope this article is helpful to you and inspires you to use jQuery more flexibly in web design.

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 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.

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'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.

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 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 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 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.
