With absolute positioning, an element can be placed anywhere on a page. In this example the heading has been placed 100px from the left of the page and 150px from the top of the page. It will remain in this position.

Styling HTML elements with CSS (Cascading Style Sheet). CSS was introduced together with HTML 4, to provide a better way to style HTML elements.

jQuery is a very powerful tool which provides a variety of traversal methods to help us select elements in a document randomly as well as in sequential method. In other words, we can say that most of the traversing methods are used to find elements from the documents.

Grouping is the method to group the selectors which have same property. It minimizes the code. We write the selectors by separating them using comma.

Introduction to jQuery and how to attach a handler to one or more events for all elements that match the selector.

Some of the most basic components we can manipulate when it comes to DOM elements are the properties and attributes assigned to those elements

The switch statement is used to select one statement from the many blocks. This is used on place of nested if…else. If there are number of if..else statements then we should use switch.

JavaScript "==" is equal to operator.

JavaScript if…else is a conditional statement that is used to check wether a condition is true or false to take a decision.

jQuery ajaxStart and ajaxComplete are two functions are very useful to show the graphics while the data is loading from server. The ajaxStart method works while the server fullfilling the service asked to it. The ajaxComplete method is called when the server fulfilled the request.

jQuery selectors allow you to select and manipulate HTML elements as a group or as a single element.

While most current browsers understand Javascript a lot of the early browsers did not. The current browsers also allow Javascript to be turned off and some people do this.

JavaScript "==" is not equal to operator.

JavaScript "===" is exactly equal to (value and type) operator.

Try not to use too many different JavaScript files. Each separate file that the browser has to load incurs an overhead. You may consider to merge and minimise JavaScript files before you publish your website. This to reduce the bandwidth usage and lower webpage load time.
