Width of Sidebar

[musicandlyrics]

I can't figure out how to expand the width of my sidebar. In the most obvious place,

.sidetd {
width: 140px;

I change that number and it doesn't change the sidebar's width at all.
I also want the width of the calendar expanded. Can anyone help tell me what i'm missing?

I figured it out!
after taking cammomiletea's advice and changing those codes, I was able to update the following section of coding:

/* the columns */
.columncontent {
font-size: $*static_font_size$*static_font_measurement;
text-align: center;
width: 140px;
background-color: $color_one;
padding: 2px;

And it worked!
