How to define path in anchor tag in blocks? I'm working on localhost server and I added an anchor tag like below in block.

&lt;a href="contactus"&gt;Contact&lt;/a&gt;


In front page it goes to the path directly, but if it is other than front page, it added the current path also, for example 

http://localhost/r4launch/content/contactus


It add the "content" in front of the path, then it return "page not found".

how to define path in anchor tag ? or is that anything I'm missing ?
You can use the base_path() function to get the url with trailing slash '/'
