Look at the name of the classes in the html block. They have been encoded to make it hard to understand.
<div id=":21r" class="ii gt m14b0b8af41495ba9 adP adO">
<div id=":21o" class="a3s" style="overflow: hidden;">
<div dir="ltr">
<div class="adL"></div>
</div>
</div>
</div>
I don't think Google engineers are so jobless to encode classes like these manually. They must have used some tools for encoding the classes. Is there any service available for doing this?

To select elements with a specific class, write a period (.) character, followed by the name of the class. You can also specify that only specific HTML elements should be affected by a class.
Yes, you can use same name for both id and class because both parameters have their own significance.
You should use a class if you need to use the same selector more than once within a page or a site. While an ID is specific to a single element, classes can be assigned to multiple elements on a page or throughout the website.
It is very possible that what you are looking at was built in Google Web Toolkit. This environment has automatic Obfuscation depending on what you are looking to release into the world, and is the main environment used by Google when creating web applications.
The process is to write your files normally with your own class and id names, and when you compile the code is automatically obfuscated (or you run it through a compressor or program to do so).
In GWT you have to write in Java, but if you are looking for options for javascript or html/css then:
