This is just a question I have

I would just like to know why if you needed to break lines of the text using the element <br> or <br />, why would you have to put it twice at the end of the line in order to break it? and also, could you mix between the two in one line? Ex: <br>this is an example.<br />

you don’t. You only need one. you can use <br> when using html5, or <br /> when you have xml.

Oh ok. Because in the html training on the site, it had me input it twice
at the end of the element for some reason
