What I did is I write my post in an HTML structure so that I can easily locate and swap the paragraph with a Call to Action button, I used HTML tables for structure, and using Javascript to swap the text.

jQuery(document).ready(function(){
  post = $('[postid]');
  postid = post.data('postid');
  lines = post.find('tr');
});

i use this code to select all <tr> and then i run the main swap function,

Right now iam using this way. I dont know is this a good way for this.

After doing Some Research I found A CMS webflow. Webflow can directly swap from the database. But I want to use WordPress

So is there any other way to do this swap? Does WordPress forum have any posts related to this topic?
