Interactive map in HTML,CSS,JS is jolting whenever I hover over it
<p>Afternoon all, I have an interactive map that is intended to be used for keeping track of locations within the UK, so when someone hovers their mouse over a selected area or dot on the map then they will be given information.</p>

<p>The code for the map is as followed, this is a mixture of HTML, CSS and jQuery to achieve the results required.</p>

<p>I have embedded this code within the following link as it is, quite long..however you can see the map there also! Enjoy.</p>
