CSS Question

Position: sticky (firefox) on a <table> element

The new value of position is very confusing to me.. (me: a stanger with a little knowlegde of CSS and English) a lot of search result give javascript/jQuery (JavaScript-framework) solutions.

In the example in bottom i have a

table
with a
thead
and
tbody
.

No matter what i cannot achieve the desire result.
Desire result is thead to be sticky to the table. sticky means when not in view the element is some kind of
position:fixed
fixed means it sticks to your screen. What i did try:


  • display: inline/block/inline-block;

  • th element
    position:sticky
    (th element is an element inside a tr witch is inside a thead element)

  • mix of
    display:inline/block
    etc; (values of property display)



I just cannot find how to achieve this sticky in firefox (supported)

Any solutions ??

(as a total stranger did notice:
position:sticky
still an experimental API and should not be used in production site http://developer.mozilla.org/en/docs/Web/CSS/position )



table {
background-color: rgba(241, 31, 0, 0.3);
width: 100%;
}
thead {
background-color: rgba(241, 0, 241, 0.3);
position: -webkit-sticky;
position: sticky;
}
th {} tbody td:nth-child(2) {
height: 200px;
}

<thead>
<tr>
<th>1</th>
<th>2</th>
<th>3</th>

Answer

Firefox seems not to allow yet 'sticky' on table childs elements.

a workaround would be to set table as block, then thead, tbody, tfoot to display:table; so one of them can be sticked.

unfortunately this breaks the table-layout and split table into few tables .. :(

you also need to set coordonates where sticky comes in action http://codepen.io/gc-nomade/pen/reoExq . not the best :(

CSS base would be like:

table {
  display: block;
}

thead {
  position: sticky;
  top: 0px;  /* trigger sticky when reaches coordonates */
}

thead, tbody, tfoot {
  display: table;
  width: 100%;
}

table {
  background-color: rgba(241, 31, 0, 0.3);
  width: 100%;
  margin-top: 1em;
  position: static;
  display: block;
}
thead {
  display: table;
  width: 100%;
  background-color: rgba(241, 0, 241, 0.3);
  position: sticky;
  top: 0px;
  /* trigger sticky when reaches coordonates */
}
tbody {
  display: table;
  width: 100%;
}
th {} tbody td:nth-child(2) {
  height: 200px;
}
