About the website
Read about the Interinstitutional Style Guide website and its features.
This is an interinstitutional website, managed by the Publications Office and hosted on the OP Portal. It uses some of the functions available on the portal, notably the possibility to log in and to add alerts. It also enables the use of personal bookmarks and settings.
The site is responsive, meaning that it can be used as easily on a tablet or a mobile phone as on a laptop or a desktop. See, for example, the countries and territories table in Annex A5.
The website aims to be accessible and can be used with assistive technologies such as screen readers. Improving the accessibility of the content is a continuous process.
The new website was released in June 2024. If you still have links to the old website, you can update them using the ‘redirections list’ (downloads an Excel file). The file contains the old and the corresponding new URLs in all 24 languages.
Bookmarks
‘Manage bookmarks’ opens a panel showing a list of recommended bookmarks. Log in to add your own bookmarks. You can then rename them, create folders and use drag and drop to change the order.
Bilingual view
A bilingual view is possible in the first three parts, which are common to all language versions. It is not possible in the fourth part because the content there is language specific. The annexes are also excluded from the bilingual view as their content varies from language to language or is sorted in alphabetical order according to the language.
The bilingual view allows you to find the equivalent rule or information in another language easily.
Simply click the blue ‘Bilingual view’ button towards the top of the ISG pages.
You can display any two languages side by side. Click on the ‘×’ to return to the page you started from.
Toolbar
From the toolbar on the left you can easily find the content you are looking for via the table of contents, the search and the index. You can also find other formats of the style guide, along with settings.
On a tablet or a mobile phone the toolbar always appears at the bottom.
Contents
Click on the contents icon in the toolbar to access the different parts of the style guide. The dropdown menu that opens helps you navigate directly to the section you need.
You can also reach the complete table of contents on a single page via the link ‘Expanded table of contents’ in the footer.
Search
The search box suggests predefined terms to refine results, making it easier to find the information you need.
Index
The alphabetical list of keywords is useful for quickly accessing the specific content you are searching for. You can also filter by keyword.
PDF versions
From the toolbar, you can open the PDF that is created each time the website is updated. You can consult it online, where it will open at the page you are currently viewing in the browser. Alternatively, you can download it directly.
In addition, a PDF version designed for printing is created once a year or after major updates. Each of these PDFs is a separate edition of the style guide, has a full set of identifiers and can be found on the EU Publications Office website. All modifications compared with the latest edition (20 April 2026) are marked in green on the style guide website.
Settings
In the settings, you can choose to hide the toolbar text descriptions, move the toolbar to the right and continue where you left off the last time you visited the website. To change the settings, you need to be logged in.
Footer
Links to the newsletter, expanded table of contents and FAQs can also be found in the footer.
Alert
You can create an alert from the 'News' page of the website, to be notified daily or weekly about modifications or other news.
User account
When you log in to the site, you are logging in to the OP Portal. This explains why you are given the choice of using EU Login or a dedicated OP Portal account. Once logged in, your name will appear and you will be able to see account details, profile lists and alerts that are valid on the OP Portal as well as on the style guide website.
