This project is very simple and easy to use. The user can get to know how this project can be built with ease.

Also you can use this editor as an code editor. This means that you can now use simple hmtl tags to write your notes.

STEP 1 :

Create Javascript file (pell.min.js)

(function (global, factory) {
	typeof exports === 'object' && typeof module !== 'undefined' ? factory(exports) :
	typeof define === 'function' && define.amd ? define(['exports'], factory) :
	(factory((global.pell = {})));
}(this, (function (exports) { 'use strict';

var _extends = Object.assign || function (target) { for (var i = 1; i < arguments.length; i++) { var source = arguments[i]; for (var key in source) { if (Object.prototype.hasOwnProperty.call(source, key)) { target[key] = source[key]; } } } return target; };

var defaultParagraphSeparatorString = 'defaultParagraphSeparator';
var formatBlock = 'formatBlock';
var addEventListener = function addEventListener(parent, type, listener) {
  return parent.addEventListener(type, listener);
};
var appendChild = function appendChild(parent, child) {
  return parent.appendChild(child);
};
var createElement = function createElement(tag) {
  return document.createElement(tag);
};
var queryCommandState = function queryCommandState(command) {
  return document.queryCommandState(command);
};
var queryCommandValue = function queryCommandValue(command) {
  return document.queryCommandValue(command);
};

var exec = function exec(command) {
  var value = arguments.length > 1 && arguments[1] !== undefined ? arguments[1] : null;
  return document.execCommand(command, false, value);
};

var defaultActions = {
bold: {icon: '<b>B</b>',title: 'Bold',state: function state() {return queryCommandState('bold');},result: function result() {return exec('bold');}},
italic: {icon: '<i>I</i>',title: 'Italic',state: function state() {return queryCommandState('italic');},result: function result() {return exec('italic');}},
underline: {icon: '<u>U</u>',title: 'Underline',state: function state() {return queryCommandState('underline');},result: function result() {return exec('underline');}},
strikethrough: {icon: '<strike>S</strike>',title: 'Strike-through',state: function state() {return queryCommandState('strikeThrough');},result: function result() {return exec('strikeThrough');}},
heading1: {icon: '<b>H<sub>1</sub></b>',title: 'Heading 1',result: function result() {return exec(formatBlock, '<h1>');}},
heading2: {icon: '<b>H<sub>2</sub></b>',title: 'Heading 2',result: function result() {return exec(formatBlock, '<h2>');}},
paragraph: {icon: '&#182;',title: 'Paragraph',result: function result() {return exec(formatBlock, '<p>');}},

Object.defineProperty(exports, '__esModule', { value: true });

})));

STEP 2 :

Create css file (pell.min.css)

/* Pell */
.pell{border:1px solid hsla(0,0%,4%,.1)}.pell,.pell-content{box-sizing:border-box}.pell-content{ height:100px;outline:0;overflow-y:auto;padding:10px}.pell-actionbar{background-color:#fff;border-bottom:1px solid hsla(0,0%,4%,.1)}.pell-button{background-color:transparent;border:none;cursor:pointer;height:30px;outline:0;width:30px;vertical-align:bottom}.pell-button-selected{background-color:#f0f0f0}
/* Button */
.btn {border: none;color: white;padding: 15px 32px;text-align: center;text-decoration: none;display: inline-block;font-size: 16px;margin: 4px 2px;cursor: pointer;vertical-align:middle;}.btn-blue {background-color: #008CBA;}.btn-green {background-color: #4CAF50;}.btn-red {background-color: #f44336;}.btn-gray {background-color: #e7e7e7;color:#000000;}.btn-black {background-color: #555555;}.btn-s10 {font-size: 10px;}.btn-s12 {font-size: 12px;}.btn-s14 {font-size: 14px;}.btn-s16 {font-size: 16px;}.btn-s20 {font-size: 20px;}.btn-s24 {font-size: 24px;}.btn-10p24 {padding: 10px 24px;}.btn-12p28 {padding: 12px 28px;}.btn-b2 {border-radius: 2px;}.btn-b4 {border-radius: 4px;}.btn-b6 {border-radius: 6px;}.btn-b8 {border-radius: 8px;}.btn-b10 {border-radius: 10px;}.btn-b12 {border-radius: 12px;}.btn-bdr-green {background-color: white; color: black; border: 2px solid #4CAF50;}.btn-bdr-blue {background-color: white; color: black; border: 2px solid #008CBA;}.btn-bdr-red {background-color: white; color: black; border: 2px solid #f44336;}.btn-bdr-gray {background-color: white;color: black;border: 2px solid #e7e7e7;}.btn-bdr-black {background-color: white;color: black;border: 2px solid #555555;}.btn-block{width:100%;}
/* Container */
.flex-container{display: flex;flex-wrap: nowrap;}

STEP 3:

Include css and JS file and add css code

<link rel="stylesheet" type="text/css" href="pell.min.css">
<script src="pell.min.js"></script>
<style>
   body {
    margin: 0;
    padding: 0;
    font-family: sans-serif;
   }
   .content {
    box-sizing: border-box;
    margin: 0 auto;
    max-width: 680px;
    padding: 20px;
   }
   #html-output {
    white-space: pre-wrap;
   }
   #editor{
    width:40em;
    font-family:sans-serif;
   }
   #source-editor{
   display:none;
   }
</style>

STEP 3:

Add JS code

 <script>
      var editor = window.pell.init({
        element: document.getElementById('editor'),
        actions: ['bold', 'italic', 'underline', 'heading1', 'heading2', 'olist', 'ulist', 'link', 'image', 'justifyLeft', 'justifyRight', 'justifyCenter', 'justifyFull'],
        defaultParagraphSeparator: 'p',
        onChange: function (html) {
          document.getElementById('html-output').value   = html
        }
      })
     editor.content.innerHTML = document.getElementById('html-output').value
     function TextArea(){
     editor.content.innerHTML = document.getElementById('html-output').value
     }function toggleEditor() {
     if (document.getElementById("source-editor").style.display == "none") {
        document.getElementById("source-editor").style.display = "block";
        document.getElementById("visual-editor").style.display = "none";
        document.getElementById("btn_lbl").value = "Visual Editor";
     } else {
        document.getElementById("source-editor").style.display = "none";
        document.getElementById("visual-editor").style.display = "block";
        document.getElementById("btn_lbl").value = "Source Editor";
     }
     }
    </script>

STEP 4:

Add HTML code

<div class="content">
    <form action="" method="POST">
    <h1>pellJS Editor </h1>
    <input type="button" class="btn btn-blue btn-s12 btn-10p24 btn-b6" style="float:right;" onClick="toggleEditor()" id="btn_lbl" value="Source Editor">
    <input name="art_id" type="hidden">
    <table width="80%">
    <tr><td>Title</td><td><input class="btn btn-block btn-10p24" name="title" type="text" placeholder="" style="border:1px solid #000;text-align:left;color:black"></td></tr>
    </table>
    <div id="visual-editor">
      <p><b>Editor<b>
      <div id="editor" class="pell"></div>
    </div>
    <div id="source-editor">
      <p><b>Source Editor<b><p>
      <textarea id="html-output" name="html-output" onChange="TextArea()" onBlur="TextArea()" rows="20" cols="88" style="resize:none;font-family: sans-serif;">
       <b>Hello World</b></textarea>
    </div>
    <button type="submit" class="btn btn-green btn-10p24 btn-block" style="float:right;">Source Editor</button>
    </form>
</div>
