Learn how to get rid of the “You may use these HTML tags and attributes” from WordPress


WordPress is amazing and facilitates bloggers in every aspect. Everything can be adjusted to personal taste. But there is one thing and many people including myself would like to be removed from their pages.

If you look at the bottom of your wordpress pages, then just below the comments box, you will see this.

[edsanimate animation=”tada” delay=”12″ infinite_animation=”yes” animate_on=””]

The HTML suggestions concerning the comment text



With or without the highlighter and regardless of the theme selected, this looks like the HTML code itself. It is just like handing over the engine and tires to the driver when he comes to buy a car. Lets get rid of that!

If we look at the code of my page, it is easy to spot the CLASS and ID of the HTML element responsible for that text.

[edsanimate animation=”bounceInUp” delay=”1″ duration=”3″ infinite_animation=”no” animate_on=”scroll”]



Both the ID and the CLASS of that element is form-allowed-tags. In CSS, we can make an HTML element invisible using the following code.

Now, we will simply add our CSS to the wordpress using the following menu.

Basically, click Appearance and then go to Edit CSS. Then paste your the following code and then click Save Stylesheet.

Now if you visit your page again, you will see that is is gone. The “You may use these HTML tags and attributes” message used to be at the highlighted section below.

[edsanimate animation=”zoomInRight” delay=”2″ infinite_animation=”no” animate_on=”scroll”]

  3. You can call “i” whatever you wish.
  4. “PreviousMenuClassName” is the name of the Activity where you want to go after clicking the button.

Knoppix touchpad click workaround

Problem: I can’t click with my touchpad in Knoppix. I can use USB/bluetooth mouse normally but the Laptop’s touchpad can’t be tapped to click.


  1. Go to terminal and enter the following

    knoppix@Microknoppix:~$ synclient Tapbutton1=1

  2. Now try closing the terminal by tapping the [X] in the terminal window and it will work.

Note: This only works for the current session which means if you restart knoppix, the touchpad will be back to unclickable. I will update the post as soon as I discover the permanent solution to the problem. But as far as I am concerned, I can do that on every boot 🙂


I should have known that Wifi Can also be turned on by Windows+X

Windows mobility center

Recently my laptop had a malfunction in hardware making the WiFi and sound touch buttons unusable. I tried all kind of driver and none worked. Then I tried Linux Mint 13 and it also didn’t work because the problem was in hardware.

Linux has manual controls which may turn the switches for WiFi and Sound on and off but it is not the point here.

Finally after skimming through the internet for help, I found a very easy way to trigger WiFi in windows. It is something some people including myself either do not know or are not used to. Simply pressing Windows+X buttons will produce a menu which will allow the user to turn WiFi on or off. Moreover, it allows many more facilities on the same platform. The following will help understanding.

 Press Windows + X

You will be presented with the Windows Mobility center.

Now, if you press the highlighted button (highlighted below), you will turn the WiFi on or off (unless the hardware is completely failed). That way, I was able to use WiFi without repairing my laptop. Also not the other options which you may find useful.

“Turn Wireless Off” Option highlighted.

As for those users of Knoppix who intend to use the DVD version, then there is no need to install anything because Wine comes as a pre-installed package in the DVD version.
