I thought using <div id="xyz"> helps group html elements on a page.

1. If inside the <div id="xyz"> I need to put a few different sub-elements like <input id="abc"> , <select id="def">, etc. Then what's good about using <div> at all ? I mean, anyway I am going to use the id for each subelement.

2. If you apply a stylesheet to <div id="xyz"> , does it mean this style sheet will be applied to *every* elements inside this <div> ?

1. By default a <div> will create a block element, that is a rectangle that spans the width of its container. So it's useful for layout. Applying CSS can adjust that layout in many useful and interesting ways. It's also useful as an organizational element.

2. Many CSS rules are inherited from a parent if not overridden at the child level.

Raj Ohadi, you are right. But there is lots of benefits of using <div> such as it makes web page light weight and need less coding if we are going to create number of web pages. It is much better than using table. Therefore I use it.

With a little knowledge, a cast iron skillet is non-stick and lasts a lifetime.
