Jeykll supports the use of Markdown with inline HTML tags which makes it easier to quickly write posts with Jekyll, without having to worry too much about text formatting. A sample of the formatting follows.

Highlighting for code in Jekyll is done using Pygments or Rouge. This theme makes use of Pygments by default.

for (var i = 1; i <= 10; i++) {
    console.log(i);
}

def show
  @widget = Widget(params[:id])
  respond_to do |format|
    format.html # show.html.erb
    format.json { render json: @widget }
  end
end

// count to twenty
var j = 0;
while (j < 20) {
    j++;
    console.log(j);

Alternatively, they can be shown on a new line:
