I don’t have my ipad with me, but I can see the same thing when the browser is resized. To fix this you could add “word-wrap: break-word;” to your css around line 833. Look for this –
`.five-sixths,
.four-fifths,
.four-sixths,
.one-fifth,
.one-fourth,
.one-half,
.one-sixth,
.one-third,
.three-fifths,
.three-fourths,
.three-sixths,
.two-fifths,
.two-fourths,
.two-sixths,
.two-thirds {
float: left;
margin-left: 4.166666666%; /* 48px / 1152px */
word-wrap: break-word;
}`
