What is a BORDER attribute


So I've been taking notes to make me understand coding easier. The problem is that code academy didn't really explain what the border attribute is. One example is....

    <table border="1px">
        <td> two </td>
            <td> three </td>




If you look right after the tag, you'll see it say


HTML elements are objects, and as such they have properties associated with them.


generally referred to as a tag.

<element property="value">

an element with a property attribute.

Your code contains an example of the a border attribute:

<table border="1">

Note that in HTML, numeric values do not have units like they would in CSS. HTML interprets the above as a TABLE element with a 1 pixel wide border.
