What is Inline CSS

What if there is a way in which we can test our styling without disturbing the flow of styling in our external CSS File? Let's find out -

Usually professional developers use the "External Styling" for styling a page because it is easy to maintain & manage the external css file.

But sometimes we do need to test the styling of some specific HTML tags without disturbing the external css file for which Inline CSS comes into the play.

Inline CSS is one of the styling ways in which we can target a particular tag for styling which is present anywhere in the HTML document or in the JavaScript file.

How to use Inline CSS

By using the style attribute in the opening of the HTML tag we can perform inline styling of the tag. eg. -

<h1 style="...">...</h1>

Now using this type of styling will affect the specific tag in which this styling is mentioned.

Inline styling starts with the "style" attribute followed by an equals sign "=" which will contain the value in property-value pairs format i.e "property:value" eg. -

<p style="color: red;"> Hello World😎 </p>

Here "color" is the property followed by a colon(:) which is then followed by the value "red" & ending with a semicolon.

Note: We can have as many differnt property-value pairs in the style attribute but they all should be seperated by a semicolon (;) . eg. -

 <p style="color: red;text-align: center;font-size: 0.8rem;"> Hello World😎 </p>

When Inline CSS is used

In most of the scenarios professional web developers try not to use Inline CSS but in some of the cases it is the best option that they can have. Some of the cases are -

  1. When one wants to style the Dynamic content which maybe changed by JavaScript
  2. It's best to use inline styling when we want to see the changes in an old website & then apply it to the external css file so that it does not disturb the flow of overall styling of the HTML page
  3. When one wants to style HTML e-mail

Now, Inline CSS have the the highest specificity order among all the styling in CSS. Therefore, it will override most of the rules of internal & external stylesheets with an exception of ! important declaration

<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
            color: yellowgreen;
    <p style="color: red;text-align: center;font-size: 0.8rem;"> Hello World😎 </p>

Here inline styling of < p > tag will override the internal styling (mentinoed in the head section of the HTML document ) of the < p > tag due to which our paragraph will be red in color.
