Oxygen Theme, adjusting margins and sidebars, removing "recent & more articles"

Hello —

I am trying to make some adjustments to the homepage of my website using Oxygen theme.

1) I would like to move the secondary sidebar to the left side. I have tried using both of the following with no luck:

#sidebar-secondary {
float: left;
width: 19%; /* 250 / 750 = 0.3333333333333333 */
}

AND

.sidebar-secondary {
float: left;
width: 19%; /* 250 / 750 = 0.3333333333333333 */
}

2) I would like the margins for “Recent Articles” to be narrower and to float right. I tried changing this with by changing the .hfeed which worked but also changed all the pages/content on the website as well (which I don’t want).

3) Is there an easy way to remove the “More Articles” section? I’ve looked a bit into the coding and was hoping to not predominately remove anything. I tried using <!– to –> to deactivate the code. This worked but then left a huge blank white space (larger than if I just leave what is there already). Not sure where I am making the mistake there.

Super grateful for any suggestions on any of the above.

Thank you!
