Easy Steps To Add Floating contact us Button
Important!Before we start adding the XML code, I recommend that you create a backup of your current theme. If a problem arises, you can always restore it later.
Step 1: First of all Login to your Blogger Dashboard.
Step 2: On Blogger Dashboard, click Theme.
Step 3: Click the arrow down icon next to 'customize' button.
Step 4: Click Edit HTML, you will be redirected to editing page.
Step 5: Now search the code </head>
or <body>
and paste the following Js codes just above to it.
<script defer='defer' src='https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js'/> <link href='https://cdn.statically.io/gh/wiendhy/theboegis/f6941b7c/arcontactus.css' rel='stylesheet'/>
<script defer='defer' src='https://cdn.statically.io/gh/wiendhy/theboegis/7429d8c8/contactus.js' type='text/javascript'/>
Step 6: Now add the following Javascript just above to </body>
tag. If you don't find it, it is probably already parsed which is </body>
.
My link has been inserted in this JavaScript. Please remove it and insert your own link.
