Expanding circumference of KB article in support portals

[sunny27]

Hi All,

We need suggestion to expand the circumference or border of the KB articles in portals ( KB screenshot 1.png). Now we need to minimize the size the of the screenshot which then becomes unclear. (Please refer the screenshot KB screenshot 1.png and KB screenshot 2.png)

           And For the tables we have to manually assign border values, and in order to verify if its correct or not, we have to publish the article otherwise the editor view or preview (refer  KB screenshot 3.png  doesn't shows the accurate results. Please refer the screenshot KB screenshot 3.png and KB screenshot 4.png.

Advice with any suggestion to fix these issue.
