For the blockquote issue, you can inspect the element to see what styling the
blockquote has and then create your own style for it.
To access the element inspector you can press
ctrl + shift + I on Chrome.
Once the dev tools window pops open press
ctrl + shift + C to start the element picker. You’ll notice that mousing over any page element shows you a box and element description. Hover over the part you want to investigate, in this case your bio text, and click it.
In the dev tools you should see a little section off css stylesheet.

So instead of just deleting the blockquote, you could replace it with a div and give the div a class like
bio-text. Then in your own css sheet, add all the other parts of that blockquote styling you liked, but leave out the border-left part.
