What must you do to see changes in the h1 tag after editing?

To see changes in the h1 tag after editing, it is essential to first edit and save the file before refreshing the browser. This process ensures that the changes you have made in the code are properly recorded and updated in the document that the browser is displaying. When you save your edits, you effectively overwrite the previous version of the file with your new changes.

Once the file is saved, refreshing the browser will prompt it to reload the most recent version of the file, allowing you to view the updates you have implemented. Without saving the changes first, the browser will continue to display the previous version of the file, which would not reflect your latest edits.

In web development, the typical workflow is to make changes in your code editor, save those changes, and then check the browser to confirm that the updates are visible. This is a fundamental process for maintaining an efficient workflow when making adjustments in HTML or other frontend code.
