Ok. I got everything set and need to take the forum rolling. But I am still at bay as most of my uses include posting images and videos which need to be center aligned. Can I use some other tools which like Libre Office or some HTML editor and find any ways to center my image/ video. My whole setting up server, installing NodeBB, learning and setting up the forum will be wasted if I cannot find a solution :sad:
For images you could create your own convention:
For examle you could center all images with alt-tag beginning with _ by adding the following to custom css:
.img-responsive[alt^="_"] {
margin: auto;
}
Now evey image included like  should be centered.
EDIT: For videos you may choose to center all of them, just add margin: auto; into the code I gave you here 
That's a very cool tip @frissdiegurke, I never thought of that before.. genius

I think I can say you're welcome from all of us 
@psychobunny @meetdilip @julian I appreciate your kind words 
@Cygnus what about it doesn't work?
@Cygnus I've fixed it. Here's the updated CSS:
only works on the preview
.img-responsive[alt^="_"], .topic .posts .content .img-responsive[alt^="_"] {
margin: auto;
display: block;
}
