Flexdashboard, how to remove title of container?

I like the easy container layouts of flexdashboard, but I'd like to have those containers without having to have a title on each.
For example (see photo), I have a table and graph beside each other in separate containers, but I want to get rid of the titles of each container because I will create a value box header that spans across both, so the individual container titles are redundant.
However, in flexdashboard, the only way to create separate containers is to write out a title (ie. ### Table).
Is there any way to do this?
<### Table
renderDatatable{}
<### Graph
renderPlot{}

How to separate 'Subtotal' and 'amount' to match theme?

I'm stylizing our storefront, and I'm looking to separate two divs to match the theme. When all product options are selected and add-ons are selected, I'd like the amount to be justified to the right, and the 'Subtotal' to be justified to the left. Is there any way of separating the two in CSS?
I've tried justify-content: space-between to no avail
link to website *Note, you'll have to fill in product options & choose an add on for the content to appear above the Add to Cart button.

Equally spacing content inside a material-ui Grid item

I'm using material-ui's Grid component, inside a ListItem. I'm trying to work out how to spread three columns worth of content across four columns of the material-ui layout, as follows:
Green lines indicate five of the twelve columns. In the first one is the red icon (ignore the margin to its left). That's clear. But then there are three pieces of content - Name, DOB, and an ID -- that are spread across the remaining four columns shown. The yellow lines indicate spacing between the three content pieces, which is supposed to be 1.5 rem.
I've forked a relevant material-ui demo here
If Grid items are the elements to be placed inside a Grid container, how do you handle spacing content inside an item?
EDIT: I've realized that a Grid container can indeed be nested inside a grid item, and have updated the codepen link to reflect that. What I now need to know is how to specify 1.5 rem in between each of the three content pieces. Their widths should be fixed such that the columns are respected even if the content piece is missing (e.g. there is no date -- the columns still need to stay in alignment)
Any help appreciated!

Thumbnail Navigation Problems with css position

I'm trying to create a thumbnail navigation for a slideshow. Below the main images will be a line of what appears to be dots, when you hover over them a preview appears.
I got this from a tutorial that was originally designed to be a next and prev navigation, but I am trying to convert it.
http://codepen.io/smalltrades/pen/sjrqm
I would like the dots to be spaced evenly across the bottom of the window, but as I am not completely fluent in css I haven't been able to find the right combination of settings. Currently all the dots are stacked on top of eachother.
Any thoughts?
