该存储库有一个较新版本，名为 wmd-new。正如 StackOverflow 博客中所述，此版本使用 CSS sprites 以获得更好的性能。因此工具栏是一个图形：

在此处输入图像描述

存储库中有一个用于工具栏的 PSD (Photoshop) 文件您可以编辑。基本上，您需要向 wmd.css 和 wmd.js 文件添加一个新按钮。查看 CSS 中的第 93 行，您会看到：

/* sprite button slicing style information */
#wmd-button-bar #wmd-bold-button    {left: 0px;   background-position: 0px 0;}
#wmd-button-bar #wmd-italic-button  {left: 25px;  background-position: -20px 0;}
#wmd-button-bar #wmd-spacer1        {left: 50px;}
#wmd-button-bar #wmd-link-button    {left: 75px;  background-position: -40px 0;}
#wmd-button-bar #wmd-quote-button   {left: 100px;  background-position: -60px 0;}
#wmd-button-bar #wmd-code-button    {left: 125px;  background-position: -80px 0;}
#wmd-button-bar #wmd-image-button   {left: 150px;  background-position: -100px 0;}
#wmd-button-bar #wmd-spacer2        {left: 175px;}
#wmd-button-bar #wmd-olist-button   {left: 200px;  background-position: -120px 0;}
#wmd-button-bar #wmd-ulist-button   {left: 225px; background-position: -140px 0;}
#wmd-button-bar #wmd-heading-button {left: 250px; background-position: -160px 0;}
#wmd-button-bar #wmd-hr-button      {left: 275px; background-position: -180px 0;}
#wmd-button-bar #wmd-spacer3        {left: 300px;}
#wmd-button-bar #wmd-undo-button    {left: 325px; background-position: -200px 0;}
#wmd-button-bar #wmd-redo-button    {left: 350px; background-position: -220px 0;}
#wmd-button-bar #wmd-help-button    {right: 0px; background-position: -240px 0;}

请注意上面的 wmd-button-bar 的原始样式以及 left 的使用方式。

There is a newer version of the repository called wmd-new. As described on the StackOverflow blog this version uses CSS sprites for better performance. So the toolbar is a single graphic:

enter image description here

There is a PSD (Photoshop) file for the toolbar in the repository that you can edit. Basically you need to add a new button to the wmd.css and the wmd.js files. Look around line 93 in the CSS and you'll see:

/* sprite button slicing style information */
#wmd-button-bar #wmd-bold-button    {left: 0px;   background-position: 0px 0;}
#wmd-button-bar #wmd-italic-button  {left: 25px;  background-position: -20px 0;}
#wmd-button-bar #wmd-spacer1        {left: 50px;}
#wmd-button-bar #wmd-link-button    {left: 75px;  background-position: -40px 0;}
#wmd-button-bar #wmd-quote-button   {left: 100px;  background-position: -60px 0;}
#wmd-button-bar #wmd-code-button    {left: 125px;  background-position: -80px 0;}
#wmd-button-bar #wmd-image-button   {left: 150px;  background-position: -100px 0;}
#wmd-button-bar #wmd-spacer2        {left: 175px;}
#wmd-button-bar #wmd-olist-button   {left: 200px;  background-position: -120px 0;}
#wmd-button-bar #wmd-ulist-button   {left: 225px; background-position: -140px 0;}
#wmd-button-bar #wmd-heading-button {left: 250px; background-position: -160px 0;}
#wmd-button-bar #wmd-hr-button      {left: 275px; background-position: -180px 0;}
#wmd-button-bar #wmd-spacer3        {left: 300px;}
#wmd-button-bar #wmd-undo-button    {left: 325px; background-position: -200px 0;}
#wmd-button-bar #wmd-redo-button    {left: 350px; background-position: -220px 0;}
#wmd-button-bar #wmd-help-button    {right: 0px; background-position: -240px 0;}

Note how the original styling of wmd-button-bar and the how left is being used above.
