1.1 Why jQuery?<\/h3>\n\n- It helps in improving the application performance and increasing the developer\u2019s productivity<\/li>\n
- It helps in developing the browser compatible web-page<\/li>\n
- It helps in implementing the UI related critical functionality without writing the several lines of codes<\/li>\n
- It is fast and extensible i.e. developers can use the jQuery library to implement the customized behavior<\/li>\n
- It is simpler and easy to learn<\/li>\n<\/ul>\n

1.2 jQuery css() Method<\/h3>\n
The jQuery css()<\/code> method is an inbuilt function that applies the CSS properties to the selected DOM elements<\/span>. Always remember, this method does not modify the content of the jQuery object and it solely applies the CSS properties on the DOM elements. Over here represent the simple syntax to practice this method.<\/p>\nSnippet<\/em><\/span><\/p>\n$(selector).css({ propertyName, propertyValue });<\/pre>\nHere,<\/p>\n
\n- The
propertyName<\/code> attribute specifies the CSS properties like color, padding, font-weight, etc<\/li>\n- The
propertyValue<\/code> attribute specifies the values of the CSS properties like red, 5px, bold, etc<\/li>\n<\/ul>\nThese new APIs make a developer life easier, really! But it would be difficult for a beginner to understand this without an example. Therefore, let us create a simple application using the jQuery library.<\/p>\n
2. jQuery css() Method Example<\/h2>\n
Here is a systematic guide for implementing this tutorial using the jQuery library.<\/p>\n
2.1 Tools Used<\/h3>\n
We are using Eclipse Kepler SR2, JDK 8 and Maven. Having said that, we have tested the code against JDK 1.7 and it works well.<\/p>\n
2.2 Project Structure<\/h3>\n
Firstly, let us review the final project structure if you are confused about where you should create the corresponding files or folder later!<\/p>\n![\"jQuery](\"http:\/\/www.webcodegeeks.com\/wp-content\/uploads\/2018\/09\/jQuery_css_project_structure_guide_1.jpg\")
<\/a>Fig. 1: Application Project Structure<\/figcaption><\/figure>\n2.3 Project Creation<\/h3>\n
This section will show on how to create a Java-based Maven project with Eclipse. In Eclipse Ide, go to File -> New -> Maven Project<\/code>.<\/p>\n![\"jQuery](\"http:\/\/www.webcodegeeks.com\/wp-content\/uploads\/2018\/09\/jQuery_css_project_guide_1.jpg\")
<\/a>Fig. 2: Create a Maven Project<\/figcaption><\/figure>\nIn the New Maven Project window, it will ask you to select project location. By default, ‘Use default workspace location’ will be selected. Just click on next button to proceed.<\/p>\n![\"jQuery](\"http:\/\/www.webcodegeeks.com\/wp-content\/uploads\/2018\/09\/jQuery_css_project_guide_2.jpg\")
<\/a>Fig. 3: Project Details<\/figcaption><\/figure>\nSelect the ‘Maven Web App’ Archetype from the list of options and click next.<\/p>\n![\"jQuery](\"http:\/\/www.webcodegeeks.com\/wp-content\/uploads\/2018\/09\/jQuery_css_project_guide_3.jpg\")
<\/a>Fig. 4: Archetype Selection<\/figcaption><\/figure>\nIt will ask you to ‘Enter the group and the artifact id for the project’. We will input the details as shown in the below image. The version number will be by default: 0.0.1-SNAPSHOT<\/code>.<\/p>\n![\"jQuery](\"http:\/\/www.webcodegeeks.com\/wp-content\/uploads\/2018\/09\/jQuery_css_project_guide_4.jpg\")
<\/a>Fig. 5: Archetype Parameters<\/figcaption><\/figure>\nClick on Finish and the creation of a maven project is completed. If you see, it has downloaded the maven dependencies and a pom.xml<\/code> file will be created. It will have the following code:<\/p>\npom.xml<\/em><\/span><\/p>\n<project xmlns=\"http:\/\/maven.apache.org\/POM\/4.0.0\" xmlns:xsi=\"http:\/\/www.w3.org\/2001\/XMLSchema-instance\" xsi:schemaLocation=\"http:\/\/maven.apache.org\/POM\/4.0.0 http:\/\/maven.apache.org\/xsd\/maven-4.0.0.xsd\">\r\n\t<modelVersion>4.0.0<\/modelVersion>\r\n\t<groupId>com.jquery<\/groupId>\r\n\t<artifactId>jQueryCss<\/artifactId>\r\n\t<version>0.0.1-SNAPSHOT<\/version>\r\n\t<packaging>war<\/packaging>\r\n<\/project>\r\n<\/pre>\n3. Application Building<\/h2>\n
Let us create an application to understand the basic building blocks of this tutorial.<\/p>\n
3.1 Load the jQuery Library<\/h3>\n
Since it is a pure JavaScript framework, so developers should add its reference using the <script><\/code> tag.<\/p>\n<script type=\"text\/javascript\" src=\"resource\/js\/jquery-3.3.1.min.js\"><\/script>\r\n<\/pre>\nDevelopers can either download the jQuery from the official website and the application will then directly load the jQuery library from the local drive or they can also include the direct CDN link under the script<\/code> tag.<\/p>\n3.2 Define the Application<\/h3>\n
Next, we will define the sample application using the HTML tags.<\/p>\n
<button id=\"apply\" type=\"submit\" class=\"btn btn-default\">Apply Css<\/button>\r\n<div>\u00a0<\/div>\r\n\t\r\n<ul id=\"children\" class=\"list-group\">\r\n\t<li id=\"tech1\" class=\"list-group-item\">JavaScript<\/li>\r\n\t<li id=\"tech2\" class=\"list-group-item\">jQuery<\/li>\r\n\t<li id=\"tech3\" class=\"list-group-item\">AngularJs<\/li>\r\n\t<li id=\"tech4\" class=\"list-group-item\">HTML\/CSS<\/li>\r\n\t<li id=\"tech5\" class=\"list-group-item\">NodeJs<\/li>\r\n<\/ul>\r\n<\/pre>\n3.3 Define a jQuery Function<\/h3>\n
In this step, we\u2019ll demonstrate the jQuery css()<\/code> method that will add the CSS properties to all the <li \/><\/code> elements on a button click. Add the following code to the jQuery function.<\/p>\n$(document).ready(function() {\r\n\t\/\/ Apply Css\r\n\t$(\"#apply\").click(function() {\t \t\r\n\t\t$(\"li\").css({\"color\": \"darkviolet\", \"font-size\": \"22px\"});\r\n\t});\t \r\n});\r\n<\/pre>\n3.4 First jQuery Application<\/h3>\n
Complete all the above steps and save the file. Let us see the sample code snippet.<\/p>\n
index.jsp<\/em><\/span><\/p>\n<%@ page language=\"java\" contentType=\"text\/html; charset=ISO-8859-1\" pageEncoding=\"ISO-8859-1\" %>\r\n<!DOCTYPE html PUBLIC \"-\/\/W3C\/\/DTD HTML 4.01 Transitional\/\/EN\" \"http:\/\/www.w3.org\/TR\/html4\/loose.dtd\">\r\n<html>\r\n\t<head>\r\n\t <title>IndexPage<\/title>\r\n\t <meta http-equiv=\"Content-Type\" content=\"text\/html; charset=ISO-8859-1\">\r\n\t\r\n\t <link rel=\"stylesheet\" type=\"text\/css\" href=\"https:\/\/maxcdn.bootstrapcdn.com\/bootstrap\/4.1.3\/css\/bootstrap.min.css\">\r\n\t \r\n\t <script type=\"text\/javascript\" src=\"resource\/js\/jquery-3.3.1.min.js\"><\/script>\r\n\t <script type=\"text\/javascript\">\r\n\t $(document).ready(function() {\r\n\t \/\/ Apply Css\r\n\t $(\"#apply\").click(function() {\t \t\r\n\t \t$(\"li\").css({\"color\": \"darkviolet\", \"font-size\": \"22px\"});\r\n\t });\t \r\n\t });\r\n\t <\/script>\r\n\t<\/head>\r\n\t<body>\r\n\t <div class=\"container\">\r\n\t <h2 align=\"center\" class=\"text-primary\">jQuery css() Example<\/h2><hr \/>\r\n\t <div>\u00a0<\/div>\r\n\t\r\n\t <!------ jQuery css() Example ------>\r\n\t <button id=\"apply\" type=\"submit\" class=\"btn btn-default\">Apply Css<\/button>\r\n\t <div>\u00a0<\/div>\r\n\t\t \r\n\t <ul id=\"children\" class=\"list-group\">\r\n\t <li id=\"tech1\" class=\"list-group-item\">JavaScript<\/li>\r\n\t <li id=\"tech2\" class=\"list-group-item\">jQuery<\/li>\r\n\t <li id=\"tech3\" class=\"list-group-item\">AngularJs<\/li>\r\n\t <li id=\"tech4\" class=\"list-group-item\">HTML\/CSS<\/li>\r\n\t <li id=\"tech5\" class=\"list-group-item\">NodeJs<\/li>\r\n\t <\/ul>\t \t\r\n\t <\/div>\r\n\t<\/body>\r\n<\/html>\r\n<\/pre>\n4. Run the Application<\/h2>\n
As we are ready for all the changes, let us compile the project and deploy the application on the Tomcat7 server. To deploy the application on Tomat7, right-click on the project and navigate to Run as -> Run on Server<\/code>.<\/p>\n![\"jQuery](\"http:\/\/www.webcodegeeks.com\/wp-content\/uploads\/2018\/09\/jQuery_css_project_deploy_guide_1.jpg\")
<\/a>Fig. 6: How to Deploy Application on Tomcat<\/figcaption><\/figure>\nTomcat will deploy the application in its web-apps folder and shall start its execution to deploy the project so that we can go ahead and test it in the browser.<\/p>\n

Open your favorite browser and hit the following URL to display the application\u2019s index page.<\/p>\n
