To specify how HTML components will be presented, utilize the CSS file.
Including a CSS file in an HTML document can be done in a number of ways. JavaScript can be used to import a CSS file into the HTML text.

- Set the link element's properties to zero.

Step By Step Guide On How To Link JavaScript To HTML And CSS :-
<html> <head> <title>My Example</title> <script src="/html/talkerscode/example.js"></script> </head> <body> <button onClick="JavaScript:exampleFunction()">Click Me</button> </body> </html>
- First, we open <html> then It is common practice to link to external JavaScript files from the document's <head>, but it is not necessary.
- The document's <body> element is another possible location for the link. For performance concerns, a greater number of developers are really linking up their Javascript from the HTML document's bottom (just prior to the closing </body> element).
- By doing this, the rest of the HTML page can load immediately without having to wait for the download of external JavaScript resources.
- But, there might be circumstances in which putting it in the <head> is preferable (for instance, if the JavaScript must be accessible to the page as it loads).
- Then we create a button for clicking the object.
- Then we close program using </body></html>
Conclusion :-
As a result, we have successfully learned how to link javascript to HTML and CSS. Javascript code can be linked to an HTML document using the <script> tag.

Using the type attribute, the kind of script can be expressly stated. If you omit this attribute, JavaScript will be taken into account as the script's language.
I hope this article on how to link JavaScript to HTML and CSS helps you and the steps and method mentioned above are easy to follow and implement.
