Le contenue texte déborde du cadre en bas

tu peut faire un exemple merci pour un cadre commentaire juste pour me rendre compte

exemple :
<section class="commentaire">

<!-- Début dés qu'un topic sera résolue -->
<section class="commentairestatresolu">Statut du sujet : RESOLU (28/04/2015 à 16:21)</section>
<!-- Fin dés qu'un topic sera résolue -->


<!-- Début date et compteur -->
<section class="commentairehaut">

<div class="commentairedate">Posté Il y a 1 seconde</div>
<div class="commentairecompteur"># 1</div>

</section>
<!-- Fin date et compteur -->


<!-- Début auteur et titre message et message -->
<section class="commentairemilieu">

<div class="commentairepost">

<div class="commentairemessage">Message du auteur
<p> jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj, hhhhhhhhhhhh, gggggggggggggggggggg, dddddddddddddddddd </p>
<p>jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj, hhhhhhhh, ,ggggggggggggggggggg, dddddddddddddddddd</p>
<p>jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj, hhhhhhhh, ,ggggggggggggggggggg, dddddddddddddddddd</p>
<p>jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj, hhhhhhhh, ,ggggggggggggggggggg, dddddddddddddddddd</p>
<p>jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj, hhhhhhhh, ,ggggggggggggggggggg, dddddddddddddddddd</p>

<p>jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj, hhhhhhhh, ,ggggggggggggggggggg, dddddddddddddddddd</p>

</section>
<!-- Fin auteur et titre message et message -->


<!-- Début bouton remonter et bouton signaler etc.... -->
<section class="commentairebas">

<div class="commentairebouttongauche">remonter</div>
<div class="commentairebouttondroite">autre bouton</div>

</section>
<!-- Fin bouton remonter et bouton signaler etc.... -->

et pour le css par exemple:
.commentairemessage
[
postion : fixed;
left : 7%;;
bottom: 20%;;
border-color:#CCCCCC; /* on affiche la couleur de la bordure */
border-style: solid; /* on affiche le style de l'a bordure */
border-width:0px 0px 0px 0px; /* top right bottom left */
margin:0px 0px 0px 0px;/* top right bottom left */
padding:0px 0px 0px 0px;/* top right bottom left */

}

sachant que la balise <p></p> et plus pratique que faire un <br />

je pense qu'il faut que tu règle ton padding mais sinon pour ton message tu fait un truc comme ca :
<p> jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj, hhhhhhhhhhhh, gggggggggggggggggggg, dddddddddddddddddd ........jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj, hhhhhhhh, ,ggggggggggggggggggg, dddddddddddddddddd
jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj, hhhhhhhh, ,ggggggggggggggggggg, dddddddddddddddddd
jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj, hhhhhhhh, ,ggggggggggggggggggg, dddddddddddddddddd
jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj, hhhhhhhh, ,ggggggggggggggggggg, dddddddddddddddddd
jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj, hhhhhhhh, ,ggggggggggggggggggg, dddddddddddddddddd
jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj, hhhhhhhh, ,ggggggggggggggggggg, dddddddddddddddddd
jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj, hhhhhhhh, ,ggggggggggggggggggg, dddddddddddddddddd
jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj, hhhhhhhh, ,ggggggggggggggggggg, dddddddddddddddddd</p>

je referais sans car là ca casse tout les cadres

ok
