<!-- Your existing logo -->
<img src="old_logo.png" alt="Old Logo">
</header>

Explanation:
1. HTML Structure: The HTML structure represents a basic webpage with a header section containing an image tag (<img>
). This tag includes the existing logo with the src
attribute pointing to the old logo file (old_logo.png
).
Script Section: The script section uses JavaScript to change the logo. It waits for the DOMContentLoaded event, ensuring the HTML content is fully loaded before executing the script. The
querySelector
method finds theimg
tag within the header, and thesrc
attribute is updated with the file path of the new logo (new_logo.png
). Additionally, thealt
attribute is updated to provide alternate text for the new logo.Replacement: To replace the existing logo, replace the
old_logo.png
file path in the HTML with the file path of your new logo (new_logo.png
).
This code updates the logo displayed on your website by using JavaScript to change the src
attribute of the existing logo image tag to the file path of the new logo.
