why build a site from scratch when you can use this.........

Yup. Your welcome

Why not to do anything yourself? why not sewing your own clothes, growing your own veggies, designing your home yourself with all these DIY stuff?

Home-made is one way to do things, and usually its more difficult than it seems. especially if you want to change even the smallest thing in the set up tools you get to 'do it yourself'.
the other way is leave it to be done by pros, i.e. a tidy job, a web adapted your needs and an 'insurance' it would work properly with other interfaces, applications atc.

most websites do need to addapt themselves to different localities and settings, and therefor need to be designed professionally.

if you already got that then u need to find alternative source.if not this one will really help u.

redesign your website can be just like a taking cup of coffee.if you have this software.

m not very sure how this will help u out .but if u r interested just have look.

learning does not cost u.right?

Why not build it from scratch? You can hold your head high and say you wrote the code all by your lonesome. Plus, you can satisfy customer needs as you are building to their specification. Off the shelf/generic products will not always have the exact design you or your customer are looking for. Not to mention, not building it from scratch is taking away the best part of being a web designer.
