Open your web browser and navigate to the video hosting service website where your desired video is hosted.
Find the video you want to embed on the hosting service's website. This could be on the video's dedicated page or within a video library or playlist.
Look for an option to get the embed code for the video. This is usually found near the video player or in the video's sharing options.
Click on the provided embed code or copy it to your clipboard using the designated copy button or right-click menu.
Open your HTML file in a text editor and find the section where you want to embed the video. Paste the copied embed code at that location.
If the embedded video appears too large or too small, you can modify its dimensions by adjusting the width and height attributes in the embed code or using CSS styles.
