If you’re interested in front-end engineering, you’ve definitely heard of Cascading Style Sheets. Cascading Style Sheets, or CSS, is a style sheet language used to develop a consistent look and feel for all the web pages of an application. CSS separates content from presentation, providing complete flexibility in designing a website. Engineers love working with CSS.
If you’re interested in, and plan to interview for, a CSS role, check out our technical interview checklist, interview questions page, and salary negotiation e-book to get interview-ready!

There are three ways to integrate CSS into an HTML page:
Inline CSS contains the CSS property in the body section, attached with the element. This style is specified within the HTML tag using the ‘ style’ attribute.
Example:
<!DOCTYPE html>
<html>
  <head>
    <title>Inline CSS</title>
  </head>
  <body>
    <p style = “color:#009999; font-size:40px;
        font-style:italic; text-align:center;”>
      Interview Kickstart
    </p>
   </body>
</html>
Internal CSS can be used to style a single HTML page uniquely. Here, the CSS file must be placed inside the HTML page in the ‘Head’ section.
Example:
<!DOCTYPE html>
<html>
  <head>
    <title>Internal CSS</title>
    <style>
      .main {
        text-align:center;
      }
      .IK {
        color:#009999;
        font-size:50px;
        font-weight:bold;
      }
      .interview {
        font-style:bold;
        font-size:20px;
      }
    </style>
  </head>
  <body>
    <div class = “main”>
      <div class =”IK”>Interview Kickstart</div>
      <div class =”interview”>
        Interview Kickstart is like a fitness coach which guides you to achieve your dream job.
      </div>
    </div>
  </body>
</html>
External CSS contains a separate CSS file having a .css extension. This file contains only styling properties with the help of tag attributes. It should be linked to the HTML file using the ‘link’ tag. This CSS file can be used on multiple web pages.
Example:
ik.css
body {
  background-color:powderblue;
}
.main {
  text-align:center;
}
.IK {
  color:#009900;
  font-size:50px;
  font-weight:bold;
}
#interview {
  font-style:bold;
  font-size:20px;
}
HTML File
<!DOCTYPE html>
<html>
  <head>
    <link rel=”stylesheet” href=”ik.css”/>
  </head>
  <body>
    <div class = “main”>
      <div class =”IK”>Interview Kickstart</div>
      <div id =”interview”>
        Interview Kickstart is like a fitness coach which guides you to achieve your dream job.
      </div>
    </div>
  </body>
</html>
The advantages of using CSS are:
ID: IDs are unique. Each ID can be assigned to only one single element. IDs are used for a specific styling of an element.
Syntax:
<div id=’submit’>
#submit {
Position: absolute;
}
Class: Classes are not unique. Multiple elements can have the same class. A class is a collective way of styling multiple elements together. Multiple classes can be added to a single element to achieve the desired style.
Syntax:
<div class=’button’>
.button {
font-color: yellow;
}
Following are some important frameworks in the web development industry:
The ‘float property’ places an element on the left or the right side of its container, allowing text and other inline elements to wrap around it.
Usage:
float: none;
float: left;
float: right;
There are four types of media properties:
You can use the ‘background-repeat’ property to control image repetition:
h1 {
background-repeat: none;
}
The background-attachment property sets a background image to scroll with the rest of the page or stay fixed.
Example of a background-image that is fixed:
body {
 background-image: url(“img_tree.gif”);
 background-repeat: no-repeat;
 background-attachment: fixed;
}
Tweening is a process that creates intermediate frames between two images to get the appearance of the first image, which develops into the second image. It is used, primarily, to create animations.
The gradient is a property that allows for smooth transitioning between two or more specified colors. There are two types of gradients in CSS:
Here are 3 quick tips to for your CSS interview preparation:
Learn all about modern HTML tags and practices. You should be able to answer questions such as “What is the proper way to embed a video?†or“How do you handle non-standard fonts?â€
The company you interview with might ask about weird or quirky CSS Selectors. You’ll have to understand these well.
The most important thing is to understand the interview process of the company you’re interviewing at; prepare for all relevant topics and skills.
