p element inside div is wider than the parent div

Question

Take a look at the link. The p element within it's parent has more width. I want to display p within the dialog box. How would I do this?

.dialog-box {
margin:0 auto;
width:300px;
height:200px;
background-color:#326A16;
-webkit-filter:drop-shadow(0px 0px 5px #000000);
border-radius:20%/34%;
}
.dialog-box:before {
content:"";
position: absolute;
width: 0px;
height: 0px;
border-right: 21px solid transparent;
border-left: 18px solid transparent;
border-top: 42px solid #326A16;
margin:195.71428571428572px 90px;
}
.dialog-box p {
display:inline;
margin:10% 14%;
text-wrap:normal;
}

Answer 1

Update your .dialog-box:

.dialog-box p {
    display: block;
    margin:10% 14%;
    width: 200px;
    word-wrap: wrap;
    word-break: break-all;
    padding-top: 30px;
}

3 things to do here:

1. display: inline does not work in your case; you have to use the width & height of p element
2. You have to wrap & break the words using word-wrap and word-break
3. You probably need to place the words inside the green dialog, using padding-top

Side note:

There is no point to set margin with so many decimal places. Use integers only.
