Please tell me how to make the site displayed in the center? Without adaptability, I just put the whole site in a div and set the desired parameters in css
#center { width: 960px; height: 100%; margin: 0 auto; text-align: left; background: white; } , but now I am making a website on the bootstrap and I need adaptability, how to make the div container not hold 960px width when reducing the screen?
