Animate second level bullet points in slidify

569 views Asked by At

I am trying to get the second (lower) level bullet points in io2012 to animate separately from their parent bullet point, like this:

>* First level animates by itself
  >+ Second level then animates by itself
>* Another first level animates by itself

I've tried several workarounds with HTML like using >* in place of >+ while attempting to indent the bullet with <div style="padding-left: 1em">>* Second level animated by itself.

However this just indents the text but not the bullet point. My experimentation with <li style="padding-left: 1em">...</li> similarly failed.

If there is no HTML solution, does the solution involve either of CSS or JavaScript?

If you are willing to go with a slightly hacky workaround, I have had success inserting .fragment at the start of paragraphs and bullets that I wanted to animate (some other things with my slides were conflicting with the >- shortcut, though I still have not figured out what).

In any case, this should work, even if it is a bit kludgy.

- .fragment First level animates by itself
    - .fragment Second level then animates by itself
- .fragment Another first level animates by itself

(.fragment adds a div class "fragment" to the following paragraph or item)

If you want a sub level menu to increment, you could set a counter-increment in the css like demonstrated in the following snippet:

ol {
    counter-reset: item
}
li {
    display: block;
}
li:before {
    content: counters(item, ".")" ";
    counter-increment: item
}
<ol>
    <li>one</li>
    <li>two
        <ol>
            <li>two.one</li>
            <li>two.two</li>
            <li>two.three</li>
        </ol>
    </li>
    <li>three
        <ol>
            <li>three.one</li>
            <li>three.two</li>
            <ol>
                <li>three.two.one</li>
                <li>three.two.two</li>
            </ol>
        </ol>
    </li>
    <li>four</li>
</ol>

However if numerical lists is not what you had in mind, there are a number of ways you can increment a list using various list-style types

 h2.title {
     font-size: 20px;
     font-weight: 800;
     margin-left:-20px;
     padding: 12px;
     counter-increment: ordem;
 }

li.heading {
     font-size: 16px;
     font-weight: bold;
     padding: 12px;
    list-style-type:none;
 }


 .bullet {
     counter-reset: bullet;
     padding-left: 12px;
 }
 .bullet li {
     list-style-type: none;
    
 }
 .bullet li:before {
     counter-increment: bullet;
     content: counter(ordem)"." counter(bullet)" ";
 }
 ol.none {
     list-style:none!important
 }
li.s2sub::before {
     counter-increment:none!important;
    content:none!important;
 }
 li.s2sub {
     list-style:upper-alpha;
 }
 li.s3sub::before {
     counter-increment:none!important;
    content:none!important;
 }
 li.s3sub {
     list-style-type:circle;
 }
li.roman::before {
     counter-increment:none!important;
    content:none!important;
 }
 li.roman {
     list-style:lower-roman inside;

 }
