Responsive tables

The responsive table will display a horizontal scroll bar if the screen is too small to display the full content. The following description applies to the table added using the markdown card.

By default, the table adapts to the window width. If you have a table that is too wide, you can add a container <div class="responsive-table"> element with around the table, and it will display a horizontal scroll bar when needed.
Step-by-Step

<div class="responsive-table">

| # | Heading | Heading | Heading | Heading | Heading |
|:--|:--------|:--------|:--------|:--------|:--------|
| 1 | Cell    | Cell    | Cell    | Cell    | Cell    |
| 2 | Cell    | Cell    | Cell    | Cell    | Cell    |
| 3 | Cell    | Cell    | Cell    | Cell    | Cell    |

</div>

Markdown table syntax is quite simple. It does not allow row or cell spanning as well as putting multi-line text in a cell. The first row is always the header followed by an extra line with dashes - and optional colons : for forcing column alignment.

Tip: What it takes to generate a table?

Editing a theme

To edit files, you will need to unzip the theme archive — at this point you will have access to the necessary files indicated in the theme documentation.

Step-by-Step
  1. To edit your theme files, download a copy of the theme. For this purpose go to the 'Design & branding' settings in the Ghost Admin and click 'Change theme' in the bottom right corner.
  2. Use the 'Installed' tab menu in the upper right corner to download your theme, then unzip the theme locally.
  3. Once the theme is unzipped, the files can be edited using an code editor – make the changes indicated in the theme documentation.
You can edit files using applications (code editor) such as Sublime Text, Visual Studio Code or Brackets. Using native text editors like TextEdit on macOS may add formatting may cause the theme to work incorrectly.
  1. When you’ve finished making changes to the theme code, re-zip the theme directory for uploading back to Ghost.
To create a zip archive on a macOS, right-click on the theme folder to view the context menu. Then, click the 'Compress' option. On Windows right-click on the theme folder, select 'Send to', and then select 'Compressed (zipped) folder'.
  1. To upload a theme, go to the 'Design & branding' settings in the Ghost Admin and click 'Change theme' in the bottom right corner.
  2. Then click the 'Upload theme' button in the upper right corner.
  3. Once uploaded, click 'Activate' to activate the theme on your site.
Advanced

Updating a theme

Updates to the theme ensure compatibility with the latest Ghost version, performance improvements and minor bug fixes. So it is important that you use the latest available theme version.

If your theme features custom code, updating it with the latest versions will overwrite all your customizations.

Step-by-Step
  1. Download the latest version of the theme, then unzip the archive locally.
  2. Choose a theme version that is compatible with your Ghost version.
  3. To upload a theme, go to the 'Design & branding' settings in the Ghost Admin and click 'Change theme' in the bottom right corner.
  4. Then click the 'Upload theme' button in the upper right corner.
  5. Once uploaded, click 'Activate' to activate the theme on your site.
Tip: What if you’ve already edited the theme, and want to update it without losing your changes?

That’s a bit trickier to deal with but not impossible, as long as you can remember what the changes were, or more specifically which files you edited. Unfortunately in Ghost when updating a theme you have to re-enter your changes.

For more advanced users, it can be helpful to use a comparing files app like Sublime Merge – that way you can find your changes if you don’t remember them.

Tip: After uploading the theme my settings in Design section were reset, what should I do?

The best solution is to always use the same name e.g. theme-name.zip – that way you will not have to enter your settings again after uploading a theme.

Ghost assigns the settings in the 'Design & branding' section to the name of the uploaded archive. If you upload theme-v1.zip and theme-v2.zip – Ghost will recognize them as two different themes – so the settings will reset.
Advanced

Theme translation

Translations are used both when you want to add a new language and when you want to edit current phrases used in the theme.

Editing current phrases used in the theme (Requires theme editing)
  1. You’ll need to open the theme’s ../locales/en.json file in your code editor.
  2. Change the sentences used in the theme following the pattern:
{
    "Old translate": "New translate",
    ...
}
  1. After making your changes, save your file, compress the theme into a zip format, and upload it to Ghost.
Translation to another language (Requires theme editing)
  1. Inside the ../locales/ folder, add target language file for example es.json for Spanish and pl.json for Polish (a valid language code must be used).
  2. Based on the translation from the en.json file, add translations for your language in your code editor. For example, for Spanish, use in the es.json file:
{
    "Back": "Volver",
    "Newer Posts": "Artículos Siguientes",
    "Older Posts": "Artículos Anteriores",
    ...
}
  1. After making your changes, save your file, compress the theme into a zip format, and upload it to Ghost.
  2. Then, go to the 'Publication Language' settings in the Ghost Admin.
  3. Enter the correct language code into the 'Site language' field.
