Align a list and push text to the bottom

Question

I've a 3 boxes list with title, border and brief description.

At the moment it looks like this:

I would like using only CSS to align the green borders and push all the one row titles to the bottom.

The contents and titles are dynamic so, can happen that there will be 1, 2, 3 rows for the title but I always want that titles with less rows starts from the bottom like in the example below.

I can not use Javascript!

Any suggestion will be appreciated.

At the moment the code structure is this:

HTML:

<section id="" class="boxes">
                <ul class="inline">
                    <li>
                        <article>
                            <h2>Mae hyn yn enghraifft prif llawer hwy</h2>
                            <p>
                                Mae llawer o bethau gwych cymaint yn mynd ymlaen yr haf hwn a, beth bynnag yw eich cynlluniau, nawr yw'r amser i fynd i'r afael a eich gwariant.
                            </p>
                            <a class="read-more" href="">Read more &gt;</a>
                        </article>
                    </li>

CSS:

ul.inline {
    display: inline-block;
    list-style-type: none;
    margin: 0 0 20px;
    padding: 0;
    width: 978px;
}

    ul.inline li {
        float: left;
        margin: 0 18px 0 0;
        padding: 0;
        width: 308px;
    }

        ul.inline li h2 {
            border-bottom: 5px solid #34750E;
            color: #34750E;
            font-size: 21px;
            margin: 0 0 10px;
            padding: 0 0 10px;
            position: relative;
        }

        ul.inline li a.read-more {
                color: #34750E !important;
        }

<ul class="headings">
    <li>Heading #1. Heading #1. Heading #1. Heading #1. Heading #1. </li>
    <li>Heading #2</li>
    <li>Heading #3. Heading #3. Heading #3. Heading #3. Heading #3. Heading #3. Heading #3.</li>

<ul class="matter">

CSS

ul.headings, ul.matter {
    list-style-type: none;
    vertical-align: bottom;
    white-space: nowrap;
}
ul.headings li {
    font-size:15px;
    font-weight: bold;
    border-bottom: 2px solid #888888;
    display: inline-block;
    padding: 5px 0;
    white-space: normal;
    width: 33.3%;
}
ul.matter li {
    width: 33.3%;
    display: inline-block;
    white-space: normal;
}

Got the idea from this post: How can I positioning LI elements to the bottom of UL list

Answer 2

I've set up an example using tables. This is tabular data, it has a header line, and a description line, and multiple columns.

Live Example

<table>
  <thead>
    <tr>
      <th>Event Title 1</th>
      <th>Event Title 2<br>Mutliline</th>
      <th>Event Title 3</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Event 1 description<br>Multiline!</td>
      <td>Event 2 description</td>
      <td>Event 3 description</td>
    </tr>
  </tbody>
</table>

CSS

th td {
  margin: 5px;
}
th {
  border-bottom: green 2px solid;
  vertical-align: bottom;
}
td {
  vertical-align: top;
}
