This is a tip for Contact Form 7 plugin.
In default, a tag of checkbox type (checkbox and checkbox+) and radio button type (radio) are rendered as inline, like

You can reverse checkbox-label order by using label-first option with those tags.

A replaced HTML source of checkbox in default case looks like below (I added line breaks for better viewing):
<span style="position: relative;">
<span class="wpcf7-checkbox">
<span class="wpcf7-list-item">
<input name="your-checkbox" value="ウインダム"
class="exclusive" type="checkbox">
<span class="wpcf7-list-item-label">ウインダム</span>
</span>
<span class="wpcf7-list-item">
<input name="your-checkbox" value="ミクラス"
class="exclusive" type="checkbox">
<span class="wpcf7-list-item-label">ミクラス</span>
</span>
<span class="wpcf7-list-item">
<input name="your-checkbox" value="アギラ"
class="exclusive" type="checkbox">
<span class="wpcf7-list-item-label">アギラ</span>
</span>
</span>
</span>
You can customize the layout with CSS trick.
If you want block layout instead of original inline one,
span.wpcf7-list-item { display: block; }

If you want table layout,
span.wpcf7-list-item { display: table-row; }
span.wpcf7-list-item * { display: table-cell; }
(combined with label-first option)
Notice: { display: table* } properties are not supported in Internet Explorer (even in IE7). I hate IE.
