First Step is choose a video you would like, click share, then click embed.
Next, choose your embed options and copy the iframe link.
Then, paste your iframe link into your document, along with clicking view then toggle soft wrap so it can jump down to the next line if there is no more room in the previous line.
Next, to make the video your preferred size, wrap the div around the iframe and give the div a class.
Now, position your video how you would like it by adding margin, padding, and position.
Don't forget to apply the same settings to the iframe.
Once you have finished all these steps, your video will be set.
