Bootstrap中文站那里的資料有些難以理解，也順便當個筆記寫下來。

data-target中表示需要喚醒的modal的類，其他就很簡單了

<button class="btn btn-primary" data-toggle="modal" data-target=".modal">Small modal</button>

<!-- Modal -->
<div class="modalfade" id="myModal" tabindex="⑴" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">
<span aria-hidden="true">&times;</span><span class="sr-only">Close</span>
</button>
<h4 class="modal-title" id="myModalLabel">SysInfo</h4>
</div>
<div class="modal-body">...</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
