[css-grid] editorial: typos in Subgrids section

Under Example 27, I think that there are 3 minor typos. The first 2 in the following paragraph:

If the subgrid has margins/borders/padding, the the size of those margins/borders/padding also influence sizing.

Note the duplicate the, and I also believe that influence should be influences, given the singular size subject.

Also, the last one in the last paragraph:

#subgrid { padding: 100px; }

Then a grid item in the subgrid’s first track acts as if it has an additional 100px of top, left, and bottom margin influencing the sizing of the parent grid’s tracks and the grid item’s own position.

I believe that padding should be referenced in that paragraph instead of margin.

Fixed the first one. The second one (padding vs. border) was intentional: the extra space is added outside the visible bounds of the element.
