HOw do i increase the font size of my placeholder text in instant search

[bitcoin man]

I have instant search macro for my main space. My first issue was trying to figure out how to increase the height of my search bar which isnt something thats offered within edit features on the instant search bar.

I had to use the custom css macro and do something like this

.plugin_instantsearch_searchbox { height: 35px; }

Now how do i increase the font size for my place holder text for the "search" verbiage 

I tried 

font-size: 50px;

But didnt work. Can someone help.

Can you share a screenshot of what you are trying to change?  With that, I should be able to provide some CSS that will help you.

Sorry Brent. I missed this and my apolgies. I have attached a screenshot. This is the search macro and the search buttone is too small. How do i increase the button size to make it bigger.
