How can I edit HTML directly?

[Hirotada]

Hi, there.

Is it possible to edit HTML of each page under the home directry.

Thanks in advance.

Hirotada.

for instance, I'm using "team card" that is third party app from App Center.

But I'm annoying about blank spaces between boxs. I want remove them. But they are controled by the HTML document of it's page.

So I want edit HTML and remove the blank spaces. 

Is any body have an idea?

You can edit the HTML and CSS of a theme by going to the the Theme tab and clicking on Edit HTML / CSS.

As for the Team Card app, I don't think you'll be able to edit the templates used for that since those aren't accessible for editing.
