I have a webpage that shows three levels of nested svgs generated via D3. I'm trying to change the middle set of nested svgs into a flexbox so that innermost set of svgs will be spaced to the vertical line representing the outermost flexbox, then move down if they need more space. My problem is that I am unable to make changes to the middle containers on the css page. I believe I have the right syntax but cannot even do a simple thing like change the background-color of the svgs classed as "second." This brings me no changes, for example:

.second {
  background-color: black;
}

The css works on the "container" class. I thought the difference might be because it is a div, rather than a svg, and as a result I changed all my svgs to divs - but that had no impact.

I am able to change the background-color if I do the following: 

svg {
  background-color: black;
}

This isn't what I want, exactly (I don't want to select the other svgs on the page), but I wanted to test to see if flexbox could work:

svg {
  display: flex;
  padding: 60px;
  flex: 1 1 1;
  flex-wrap: nowrap;
}

Oddly enough, it didn't work as I expected. That is, the innermost svgs were still piled up on top of one another.

Here's my code - thanks in advance,

UPDATE: Managed to add a new flexbox nested inside the old flexbox, by changing the svg2 to a div. The only problem now is that the text appended to div2 is now being treated as a child of the flexbox, which is pushing the svg to the right. (The problem only becomes apparent when the webpage is fullsize)

  • Your snippet doesn't work. Also you can use `svg.second` to select an svg with the `second` class. As a note, SVG has some different css from regular elements. – pmkro Apr 09 '19 at 18:48
  • SVG has different functions, for instance `fill:` is `background-colour` — I also don't think it's possible to use flexbox as a part of the svg, anything inside `` plays by a different set of rules. [SVG Documentation](https://developer.mozilla.org/en-US/docs/Web/SVG) – Andrew Robinson Apr 09 '19 at 18:50
  • Thanks pmkro and Andrew Robinson. Pmkro - can't figure out why my snippet is not working when its working fine in Atom. Will fix and repost soon. Andrew Robinson - thanks for the information. – oymonk Apr 09 '19 at 19:16
  • fixed the code - had forgotten to add a div to the html – oymonk Apr 09 '19 at 23:35
  • Hi Andrew Robinson and pmkro: just wanted to say thanks for telling me the svg was not amenable to becoming a flexbox. As a result, I changed the variable svgs2 into div2. Once div2 was a div, I could make it to flexbox in css. Doing this technically solved my problem - ie, all the ".second" svgs are spread across the column, with one downside: the text svg has been caught in the flexbox as well, and is no longer sitting above the second svgs. – oymonk Apr 12 '19 at 22:40

There are two tricks to solving this problem. The first trick is to remember, as @Andrew Robinson points out, that the flexbox property only applies to divs, not svgs. Therefore, the following segment of the code must be rewritten so that the element appended is a div, not an svg: 

var svgs = divs.selectAll(null)
  .data(function(d) {
    return d.values;
  })
  .enter()
  .append('svg') **// change this to: .append('div')**
  .attr("height", height + 20)

Trick two: once the above changes are made, an aesthetic issue will become apparent: the div containing the text will appear on the same line as the divs containing the rectangles. To fix this requires adding a piece of code in the css page that indicates the first child-item will be set at a width of 100%.

.first>*:first-child {
    width: 100%;
}

More information on the first-child property can be found here: First-child full-width in Flexbox
