Closed caption is an extension program that helps
you see English and another subtitles together. 🧑‍💻

If you look at only one translated caption or if you look at the existing subtitles,
there are many difficulties in watching, such as incorrect translation.

🌈 Using closed caption extension

🧐 How to update website?

1. Add the site URL that you add to the content_scripts matched array in the manifest.

🤔 how to select dom attribute?

Two pieces of information need to be added domWrapperAttrs and domAttrs.

First, domAttrs means the class,
id of the upper tag surrounding the dom showing subtitles on the screen.

This is the information of the tag surrounding the two doms
with the caption-visual-line class as shown in the image below.

Second, domWrapperAttrs means the upper dom of domAttrs.
However, domWrapperAttrs must be specified as the dom where the change occurs

If you put these two information and added website information to the manifest, please see the contents below.
