I'm trying to activate the borders of a box when the checkbox is selected but it is not working.
.radio input[type="radio"]:checked+.border {
border: 3px solid #f70024 !important;
}
<div class="col-md-3 border">
<div class="radio-inline radio input_type">
<input id="Vodafone" name="73_answer" type="radio" value="Vodafone">
<label title="Vodafone" for="Vodafone">Stack Overflow em Português</label>
</div>
</div>
