CSS Code in HTML is one of the most important frameworks for developing an appealing user interface design for viewers to connect with the application in a better and intuitive manner. CSS styling is used to give an appealing and attractive look to text, headings, buttons, background, fonts, and more.
In this blog, we will learn how to use CSS code in HTML and various different ways in which we can make it better and more precise.
What is a Cascading Style Sheet?
CSS or Cascading Style Sheet is a web development framework used to style and design the user interface of a web application. CSS used with HTML elements provide intuitive appearance and responsiveness to the web application. There are various methods to implement CSS styling to a web project. We will learn about them in this blog.
CSS Code in HTML Key Takeaways
- CSS stands for Cascading Style Sheet in web development
- CSS can be applied in three methods in web development projects i,e. Inline css, internal css and external css.
- The external CSS file contains .css in its filename.
- The internal CSS attribute is inserted within the <head> tag in the HTML document.
How to Apply CSS Effect In Web Projects?
In web development projects applying CSS has many options, you can either choose inline methods, internal methods and external methods.
Inline CSS Methods
You can apply CSS style even in the HTML tags based on individual tags for unique styling. You can apply <style> methods in the HTML element tags easily. Let us check through a simple example.
| <!DOCTYPE html>
<html> <head> <title>Inline CSS</title> </head> <body> <h1 style=”color: blue; font-size: 30px;”>This is Inline CSS</h1> </body> </html> |
We can see the CSS “style” property is applied within the <h1> tag which is known as Inline CSS. Be very careful while applying inline CSS as it loses many of the benefits of applying CSS through external spreadsheets due to complexity and mixing of content inline is less suitable especially for larger projects.
Internal CSS
This effect can be applied within the <head> tag of a HTML document in a web development project. You have to write your CSS code within the <style> tag which is inside the <head> tag. Let us take an example to understand it completely.
| <!DOCTYPE html>
<html> <head> <title>Internal CSS</title> <style> h1 { color: green; font-family: Arial, sans-serif; } p { color: gray; } </style> </head> <body> <h1>This is Internal CSS</h1> <p>Internal CSS is written inside the HTML file.</p> </body> </html> |
You just have to mention the class name or tag name to access the CSS styling of the element and use curly brackets to apply the CSS effect.
External CSS Effect
This CSS code in HTML is applied within a separate file saved with a .css extension in the web development project. It is known to be one of the most efficient method of applying CSS Code in HTML as it makes it reusable and avoid the overload and code complexity,
| <!DOCTYPE html>
<html> <head> <title>External CSS</title> <link rel=”stylesheet” href=”style.css”> </head> <body> <h1>This is External CSS</h1> <p>External CSS is best for big projects.</p> </body> </html> |
In this example, we are extracting the CSS styling from the file named as style.css in our web development project. All CSS styling properties and guidelines are present in this file.
Which Method CSS Code In HTML Framework Is Best?
Apart from all different methods available to apply CSS code in html based on different situations, but when your project is lengthy and complex then External CSS code method is one of the best and effective methods to apply CSS in your project.
It makes the code more structured and organised CSS files separately in a clean manner. It can also be reused whenever needed in multiple HTML pages with little or no changes required. It works best with modern frameworks like React, Angular and more.
However, for small and medium level projects, both inline and internal CSS code in HTMl proves to be effective. Hence, you can use them for applying CSS code in HTML easily.
Why is Inline CSS Not Advised to Use?
Out of all three methods we do not use much of inline CSS methods because of so many reasons and the first one is that it makes the complete program complex and less readable as compared to the other methods.
You cannot reuse the CSS inline methods while writing CSS code in html for other projects. It is also very hard to manage and debug especially when it comes to larger projects.
Cascading Order in CSS Code In HTML
When there is more than one style specified for an HTML element then it might be confusing and this phenomenon is known as “cascade”. For example let us consider a situation below.
| <p style=”color:green”>Welcome to PW Skills </p> |
This style mentioned in the inline CSS methods also consists of other methods such as external CSS providing effect to the same tag i,e. <p> tag. The priority level or increasing order of Cascading order in HTML are given below.
Inline Style Element > External Style Element > Internal Style Element
