wanderer on "How to Align Post Title to the Right?"

I am making an Urdu Website for my local Community and designing is done but I am unable to align post titles to the right side, please guide me in this regard.

I am using Merlin Free Theme

Here is the link to view my site
Qalamkar.pk

I want to clarify one thing here is, I tried "Custom CSS Manager Plugin" and put code;

h1.entry-title {
text-align: right;
width: 100%;
}

but it is not working as well.

Also if you can guide me , "How to right Align widget titles" as well

I didn't see h1 in your code. There is h2, however. You might also want to add float:right to your custom CSS code.

For your widget titles, you can use CSS on this: .widget ul
