Alert without close option
<p>I am using chrome browser and have installed <em>ad blocker plus</em> plugin in it.</p>

<p>When i navigate to a specific page given below. </p>

<p><a href="https://i.stack.imgur.com/HOraF.jpg" rel="nofollow noreferrer">Times of India news page</a></p>

<p>I get a alert on the page, which doesn't have a close option as shown in the screen shot. To remove the alert we need to disable <em>Ad block plus</em>. How do we create these kind of alerts and how do we close the alert without disabling <em>ad block plus</em></p>
