Use the addMarker to add highlight to the lines you want to show a highlight.

Range = ace.require('ace/range').Range;
    new Range(from, start_pos, to, end_pos), 

Here start_pos and end_pos are the lines you would like to highlight. Add CSS to the class “show-highlight”

.show-highlight {
  background: yellow; //Specify the color you would like to use
