Question

I have a table and in the end there is a button, when click on button text size in the rows of the table should be double in size. Sorry I am new to JQuery so my question seems to be silly.

Answer 1

If your page has only one table then try this

$(document).ready(function(){
  $("button").click(function(){
    $("tr").css("font-size","200%");
  });
});

Here tr is the table row and 200% means double text size
