The following worked for me:
ol {
list-style-type: none;
counter-reset: item;
margin: 0;
padding: 0;
}
ol > li {
display: table;
counter-increment: item;
margin-bottom: 0.6em;
}
ol > li:before {
content: counters(item, ".") ") ";
display: table-cell;
padding-right: 0.6em;
}
li ol > li {
margin: 0;
}
li ol > li:before {
content: counters(item, ".") ") ";
}
