Pure CSS Slide Toggle - space between toggle:checked & answers

I've been through other posts to try to find an answer to this to no avail. I'm trying to create a FAQ page with a list of questions with hidden answers that appear when the question i.e. toggle + label is clicked.

I've successfully created this using;

.message1{height:0px;font-size:0%;}

 #toggle:checked ~ .message1 {height:100px;font-size: 100%;}>

Allowing me to summon the answer to each question when the question(toggle) is clicked.

What I cannot achieve is a way to stop the answers from running into one another when multiple toggle are selected. If you test the code below and click on both toggle1, toggle2 & toggle3 you will see the problem.

Any suggestions are welcome, thanks in advance to anyone who spends time on this.

Below is the html:

 <input type="checkbox" name="toggle1" id="toggle1" />
 <label for="toggle1"><p class ="question">This is the first question</p></label>


<div class="message1">

    <p class = "answer">
     Answer text, Answer text, Answer text, Answer text, Answer text, Answer text, Answer text,
     Answer text, v Answer text, Answer text, Answer text, Answer text, Answer text, Answer text.
    </p>


</div>


 <input type="checkbox" name="toggle2" id="toggle2" />
 <label for="toggle2"><p class ="question">This is the second question</p></label>



<div class="message2">

    <p class = "answer">
     Answer text, Answer text, Answer text, Answer text, Answer text, Answer text, Answer text,
     Answer text, v Answer text, Answer text, Answer text, Answer text, Answer text, Answer text.
    </p>


</div>  


 <input type="checkbox" name="toggle3" id="toggle3" />
 <label for="toggle3"><p class ="question">This is the third question</p></label>



<div class="message3">

    <p class = "answer">
     Answer text, Answer text, Answer text, Answer text, Answer text, Answer text, Answer text,
     Answer text, v Answer text, Answer text, Answer text, Answer text, Answer text, Answer text.
    </p>


</div>  

And the css:

p.question{

}

p.answer{

 font-family:'Questrial',sans-serif;
 line-height: 2.0;
 transition: color 0.05s ease-in;
}
