CSS Interview Questions and Answers
What is CSS ?
1. CSS stands for Cascading Style Sheets and is a simple styling language which allows attaching style to HTML elements. Every element type as well as every occurrence of
a specific element within that type can be declared an unique style, e.g. margins, positioning, color or size.
2. CSS is a web standard that describes style for XML/HTML documents.
3. CSS is a language that adds style (colors, images, borders, margins…) to your site. It’s really that simple. CSS is not used to put any content on your site, it’s just there to take
the content you have and make it pretty. First thing you do is link a CSS-file to your HTML document.

Is CSS case sensitive?
Cascading Style Sheets (CSS) is not case sensitive.
However, font families, URLs to images, and other direct references with the style sheet may be.
The trick is that if you write a document using an XML declaration and an XHTML doctype, then the CSS class names will be case sensitive for some browsers.
CSS Interview Questions and Answers
What is a class? What is an ID?
A class is a style (i.e., a group of CSS attributes) that can be applied to one or more HTML elements.
This means it can apply to instances of the same element or instances of different elements to which the same style can be attached.
Classes are defined in CSS using a period followed by the class name.
It is applied to an HTML element via the class attribute and the class name.
The following snippet shows a class defined, and then it being applied to an HTML DIV element.
.test {font-family: Helvetica; font-size: 20; background: black;}
test
Also, you could define a style for all elements with a defined class. This is demonstrated with the following code that selects all P elements with the column class specified.
p.column {font-color: black;}
An ID selector is a name assigned to a specific style.
In turn, it can be associated with one HTML element with the assigned ID.
Within CSS, ID selectors are defined with the # character followed by the selector name.
The following snippet shows the CSS example1 defined followed by the use of an HTML element’s ID attribute, which pairs it with the CSS selector.
#example1: {background: blue;}
