===

I want to highlight the label of a radio button when a I click in it, I find [an answer][1] but don't work. Here my code:

**HTML**

    <div class="same-line">
		<input type="checkbox" name="417-jornadas-de-g%c3%a9nero-sin-fecha-confirmada" value="Sí" class="checkbox">
		<label class="checkbox">
		Jornadas de género (sin fecha confirmada)</label>
		<div class="clear-form"></div>
	</div> 
    <div class="same-line">
		<input type="checkbox" name="417-curso-de-fotograf%c3%ada-sin-fecha-confirmada" value="Sí" class="checkbox">
		<label class="checkbox">
		Curso de fotografía (sin fecha confirmada)</label>
		<div class="clear-form"></div>
	</div>

**CSS**

    .same-line input[type='radio'] {
        display:none;
    }
    
    .same-line label[class='checkbox'] {
        display:inline-block;
    		font-size: 12.2pt;
    }
    
    .same-line input[type='radio']:checked + label[class='checkbox'] { 
       background-color: #FFBF00 !important;
    }


Any idea?
