How can i apply "Bootstrap" on my website?Which works well in every device. Thanks..

Answer 1

There's a bit more to bootstrap than just dropping the files in (So you should spend a bit of time learning the basics), but have a look at this section to get your basic html:

http://getbootstrap.com/getting-started/#template

This will link the bootstrap javascript and css. Be sure to add any of your own javascript/css as well.

Then have a look at the overview and grid system at: http://getbootstrap.com/css/

This is how you choose the structure of your site using html as JustLearning mentioned. You'll probably be just putting your images in 1 row spanned across 4 columns.

Answer 2

The page looks bootstrapped to me but it depends on whether you meant you want your images to turn into links or made smaller into icons as that will be a new question. Responsive design is about the page fitting into the device and your page appears to fit although the images have been resized. Plus I don't see any MVC or C# or ASP.net so this is straight forward as it looks like you just have a basic HTML5 site. Here is a good link to get you started: http://docs.asp.net/en/latest/client-side/bootstrap.html
