Outline style is OK.
I did not check line-style. Please do. As the other content can be changed/improved, but not removed, as the computed value is actually important in those two cases, and likely line style.
| - `<line-style>` | ||
| - : Describes the style of the border. It can have the following values: | ||
| - `none` | ||
| - : Like the `hidden` keyword, displays no border. Unless a {{cssxref("background-image")}} is set, the computed value of the same side's {{cssxref("border-width")}} will be `0`, even if the specified value is something else. In the case of table cell and border collapsing, the `none` value has the _lowest_ priority: if any other conflicting border is set, it will be displayed. |

this is actually important to explain.
if you do
border: 20px solid dashed;and then:
border-style: hidden;the box-model of that element is changed,
and then latter add this to the element:
border-style: dotted;
the border-width is 20px when shown as dotted.
this is true for both hidden and none

I changed "computed value" to "used value", PTAL.
