What is a Modal Pop Up Box?

A pop up modal box is a floating window or viewport which has a title and some content. Modal Pop Up boxes can be used for warnings or simple subscription forms or informational layer or ‘yes or no’ dialog box or alerts and as such. These Modal Pop-ups are generally seen being used on the internet for initiating subscriptions, controlling forms like registrations, or logins. These modal pop up boxes are deliberately stationed on the same page without any re-directions to other pages.

The Modal Pop-Ups can be created using HTML, CSS, or JavaScript for which one needs to know about Bootstrap Modal, CSS Modal and/or JQuery Modal. In this article, we will discuss JQuery Modal, its step by step creation and some of its examples.

Creating a JQuery Modal

So a Modal Pop Up can be used to help our users or display added important information without refreshing or redirecting the users to the new page. By no redirection, the user feels safe and experience better since he gets the relevant information in a popup box on the same page in a familiar page.

A simple and basic Modal can be easy to create and code and also sometimes considered more appropriate than the usage of plugins.

Steps to Create JQuery Modal

Below are the basic steps of creating a basic JQuery Modal.

Step #1 – The HTML

The first step is to draft your HTML code. We will leave the scripting part for the last. We will create a rough draft of our HTML code loosely structuring our modal since our final modal will be generated by the script.

HTML Code:

The Header contains Header for the Modal Pop Up.

The Content contains the body text for the Modal.

The Footer, which includes the exit or Close button.

Step #2 – The CSS

Next, we will add our CSS for the presentation of our code and dialog box. The overlay will be made fixed according to the user’s viewport. The width and height set to 100% relative gain to the user’s viewport aiming for complete coverage of the web page.

body {font-family:Verdana, Geneva, sans-serif;} /* CSS for The Modal Dialog Box(background) */ .jqModal { display: none; /* By default, display will be hidden */ position: fixed; /* Position will be fixed */ z-index: 1; /* makes the modal box display on the top */ padding-top: 100px; /* Location of the modal box */ left: 0; top: 0; width: 100%; /* width 100%, resizable according to window size */ height: 100%; /* height 100%, resizable according to window size */ overflow: auto; /* Enable scroll if needed */ background-color: rgb(0,0,0); /* color for the Fallback */ background-color: rgba(0,0,0,0.7); /* Opacity for the fallback */ } /* CSS for Modal Dialog Content Text */ .content { background-color:#FFF; margin: auto; padding: 20px; border: 3px solid #809; width: 80%; } /* CSS for Cross or exit or close Button */ .exit { color: #809; float: right; font-size: 30px; font-weight: bold; } .exit:hover, .exit:focus { color: #000; cursor: pointer; } #modalBtn{ background-color: #4CAF50; color: white; padding: 12px 20px; margin: 10px 0; border: none; border-radius: 4px; cursor: pointer; float: left; }

Step #3 – The Script

The last step is the main and important step. It is here where we will trigger the modal pop up and make it visible for the user. We will be attaining the following points through our script:

// Set object for the modal var myModal = document.getElementById(“modalDemo”); var myButton = document.getElementById(“modalBtn”); var exitBtn = document.getElementsByClassName(“exit”)[0]; myModal.style.display = “block”; } myModal.style.display = “none”; } if (event.target == myModal) { myModal.style.display = “none”; } }

When the above code is executed, following is the output we get :

Without any doubts, you can code or create whichever type of modal for whatever aim and apply anywhere on your web page. However, there is always an easy and simple way out, some may call it more functional. You can always use plugins or templates like offered by PopupSmart which creates everything for you, you just need your aim right.
