Embeded gist unreadable

I found the following styles are applied to `{% gist %}` tag plugin (with default landscape theme)

``` css
.article-entry .gist {
margin: 0 -20px;
border-style: solid;
border-color: #ddd;
border-width: 1px 0;
background: #2d2d2d;
padding: 15px 20px 15px 0;
}
```

```
{% gist 7071963 %}
```

The negative margin make no space between the text and the container.
Also, the dark background make it difficult to read the text.
"misc" and "history" header in the gist is barely readable.

Is there any reason for the current `.article-entry .gist` sytle?

Start by locating the default landscape theme rule for `.article-entry .gist` and render the `{% gist 7071963 %}` example. Check the negative margins, spacing, dark background, and `misc`/`history` header contrast in the rendered gist. Done means the embedded gist is readable and no longer runs into surrounding text.
