SharePoint 2013 - format webpart list column text not based on a condition

Question

I would like to change the color and text size of a calculated column in a SharePoint 2013 not based on any condition.

Searching online I have only been able to to find ways of applying conditional formatting but don't have the experience to modify the JS to suit my needs.

I am using the JS Link method.

CSS seems not be an option because it will effect other lists on my page.

Any help would be much appreciated.

Updates:

Code I am using:

SP.SOD.executeFunc("clienttemplates.js", "SPClientTemplates", function() { 
    SPClientTemplates.TemplateManager.RegisterTemplateOverrides({
        OnPostRender: function(ctx) {
            var rows = ctx.ListData.Row;
            for (var i = 0; i < rows.length; i++) {
                var status = rows[i]["Aplus"]; //Replace with your column name
                var rowId = GenerateIIDForListItem(ctx, rows[i]);
                var row = document.getElementById(rowId);

                //To Change the Background color of complete row  
                row.style.backgroundColor = "#FFFF00"; //Yellow Color - You can change the color according to your requirements.
            }
        }
    });
});

To achieve this type of functionality, you can use Client Side Rendering in SharePoint 2013.

You can use below code for the same:

SP.SOD.executeFunc("clienttemplates.js", "SPClientTemplates", function() { 
    SPClientTemplates.TemplateManager.RegisterTemplateOverrides({
        OnPostRender: function(ctx) {
            var rows = ctx.ListData.Row;
            for (var i = 0; i < rows.length; i++)
            {
                var status = rows[i]["YourColumnName"];     //Replace with your column name
                var rowId = GenerateIIDForListItem(ctx, rows[i]);
                var row = document.getElementById(rowId);

                //To Change the Background color of complete row        
                row.style.backgroundColor = "#FFFF00";  //Yellow Color - You can change the color according to your requirements.

                //To Change the Background color of Particular cell
                var cell = row.cells[9];    //Replace 9 with your columns cell number
                cell.style.backgroundColor = "#FFFF00";
            }
        }
    });
});
