Can a tag button/link get focus on tab key?

[Kukulkano]

This is about Bulma 0.9.4 .

I do multiple tags with a close link element like this:

<div class="field is-grouped is-grouped-multiline" id="sel_tags">
    <div class="control">
        <div class="tags has-addons">
            <span class="tag is-info">[email protected]</span>
            <a class="tag is-delete is-warning" onclick="$(this).parent().parent().remove();"></a>
        </div>
    </div>
    <div class="control">
        <div class="tags has-addons">
            <span class="tag is-info">[email protected]</span>
            <a class="tag is-delete is-warning" onclick="$(this).parent().parent().remove();"></a>
        </div>
    </div>
</div>

The thing is, that the close link does not get focus if I try to use it only by keyboard. Is there a way to make it accessibl with tab keys?

Side question: Is there a forum or such to ask such questions?
