Is it possible to hide <style type="text/css" title="dynamic-css" class="options-output"></style> in output html?
The WordPress theme uses variable css a plants it in the header of every page.
For the sake of tidyness, is it possible to hide this output whilst still calling the styling within?
You can delete what you don’t want to see from template source code. Later dynamically create the style using javascript. The topic is widely covered. See for example this question: How to create a <style> tag with Javascript
