Step2:- Create style.css File.

.imageCodeGenerator {
width:100%;
border-collapse:collapse;
background:#32ff15;
color:#000;
font-weight: bold;
}
.imageCodeGenerator td {
border:1px solid #000;
vertical-align:top;
padding:10px;
}
.imageCodeGenerator td.toolBar {
font-size:11px;
width:300px;
height:auto;
  overflow: hidden;
padding:0px;
margin:0px;
}
.imageCodeGenerator td.toolBar table {
border-collapse:collapse;
width:100%;
}
.imageCodeGenerator td.toolBar th {
background-color:yellowgreen;
color:#fff;
padding-left:3px;
}
.imageCodeGenerator td.toolBar td {
font-size:14px;
padding:3px;
border:none;
}
.imageCodeGenerator td.toolBar textarea {
width:100%; 
font-size:1em;
}
.imageCodeGenerator td.preview {
background:#f7f7f7;
}
.imageCodeGenerator div#displayResult {
max-width:400px;min-height:200px;max-height:400px;overflow:auto;margin-bottom:10px;padding:10px;
}
.imageCodeGenerator textarea#generatedCode {
width:100%;min-height:200px;
}
.imageCodeGenerator input {
border:1px solid #000;
border-radius: 5px;
padding: 10px;
width: 100%;
}
.imageCodeGenerator input[size="3"] {
width:50px;
}
.toolBar
table
tr
th{
  font-size: 25px;
  font-weight: bold;
  color: #fff!important;
  background: blue!important;
}

.colorbor
input{
  height: 50px;
  padding: 0;
  width: 50px;
}
.refresh
span{
  background: red;
  color: #fff;
  padding: 10px;
}
table
tr
td
select{
  height: 40px;
  border-radius: 5px;
  border: 1px solid #000;
}
table
tr
td textarea{
  border-radius: 5px;
  border: 1px solid #000;
}
.code{
  position: fixed;
  bottom: 0;color: #fff;
  right: 0;
}

Step3:- Create demo.js File.

function generateCode(form){

imagesrc = document.imageCodeGenerator.ImageSrc.value;
imagewidth = document.imageCodeGenerator.ImageWidth.value;
imageheight = document.imageCodeGenerator.ImageHeight.value;
imagewidthmetric = document.imageCodeGenerator.ImageWidthMetric.value;
imageheightmetric = document.imageCodeGenerator.ImageHeightMetric.value;
margin = document.imageCodeGenerator.Margin.value;
marginmetric = document.imageCodeGenerator.MarginMetric.value;
alttext = document.imageCodeGenerator.AltText.value;
borderwidth = document.imageCodeGenerator.BorderWidth.value;
borderwidthmetric = document.imageCodeGenerator.BorderWidthMetric.value;
bordercolor = document.imageCodeGenerator.BorderColor.value;
borderstyle = document.imageCodeGenerator.BorderStyle.value;
linkurl = document.imageCodeGenerator.LinkUrl.value;
linktarget = document.imageCodeGenerator.LinkTarget.value;

output = '<!-- Codes by myprograming.com -->\n\n' +

'<!-- CSS Code -->\n' +
'<style type="text/css" scoped>\n' +
'img.GeneratedImage {\n' +
  ((imagewidth) ? 'width:' + imagewidth + imagewidthmetric + ';'  : '') + 
  ((imageheight) ? 'height:' + imageheight + imageheightmetric + ';' : '') + 
  ((margin) ? 'margin:' + margin + marginmetric + ';' : '') +
  ((borderwidth) ? 'border-width:' + borderwidth + borderwidthmetric + ';' : '') +
  ((bordercolor) ? 'border-color:' + bordercolor + ';' : '') +
  ((borderstyle) ? 'border-style:' + borderstyle + ';' : '') +
'\n}\n' +
'</style>\n\n' +

'<!-- HTML Code -->\n' +
((linkurl) ? '<a href="' + linkurl + '" target="' + linktarget + '">' : '') +
((imagesrc) ? '<img src="' + imagesrc + '" alt="' + alttext + '" class="GeneratedImage">' : '') +
((linkurl) ? '</a>' : '') +
'\n';

document.imageCodeGenerator.generatedCode.value = output;
document.getElementById('displayResult').innerHTML = output;
document.getElementById('BorderColor').style.borderColor = bordercolor;

return output;
}

Note:- Also add style.css and demo.js link in index.html File.
