+          next

Maybe changing checking if the tag is empty to checking if the tag is `<img>` will be better. Therefore, tags like `<br>` or `<p></p>` will take 1 symbol space, while `<img>` will take for example 1000 symbol space. If we want any other tags to be treated in a specific way, feel free to suggest.
