In the blogs under Wordpress are not allowed the horizontal lines (horizontal rule) that have been so helpful in the HTML of a lifetime to organize and structure a page. What inhibits these lines we have it in the CSS of wordpress. Hence we can find the following code:
hr {
display: none;
)
This simply means that when you write a line, either by editing HTML or through Tiny or some other WYSIWYG editor, does not appear.
To fix this, if you want to put any lines to separate concepts or whatever, you can simply delete this piece of code, or better to write the line in another way:
<hr style="display:block;" />
with what that line in particular it will be represented.
