What actually happens is that HTML is having a special type of handling for chars like < and > symbols, that’s the reason that it doesn’t work well with these characters.
The cause of adding wrong code may result in following problems:
>Blocks of text not appearing
>Not getting what you want to see
But there is a solution to this problem also. To fix this problem you have to ‘escape’ those characters.
For example: escaped char code for > is > .
For converting the code click”convert” button after pasting the HTML ad code in the empty box.
