We recommend you start at the top and read the full Accessible Content Guide.  However, if you are in a rush, or need a recap - here are some quick "Dos" and "Don'ts" relating to web accessibility guidelines. 

DON'T

DO

Link
Copy and paste content directly from Word or existing webpages

Paste using 'plain text' - CTRL+SHIFT+V

Copying and pasting
Use Headings based on size or how it looks Use Headings in a logical, hierarchical fashion (e.g. you can only use Heading 3 if you have already used Heading 2, and the new heading is part of that section) Headings
Use Heading 1 on the page (the page title is Heading 1) Use Heading 2 as your first section on the page Headings
Add a Header format to introductory text to make it stand out Use bold, or ask Frank Support for a custom format Headings
Assume the Heading set for an accordion is correct Check where the accordion appears e.g. does the accordion appear within a section that is already Heading 2? If so, the accordion should be set to Heading 3 Accordions
Add images to your site without adding alternative text Add descriptive, specific alternative text to describe images used in your site Images
Add images with text on them Create the content in the web editor instead.  Or use a combination of the image and a full description of everything that can be seen on the image. Images
Add vague links like, 'for more information click here' Write the destination of the link clearly into the content, for example 'for more information about the service, visit NHS mental health services' Links
Create telephone links leaving the spaces in the 'phone number' field Remove the spaces in the 'phone number' field so that the number makes sense to screen readers Links
Force links to open in a new tab (it causes issues for visually impaired users) Follow gov.uk and NHS.uk best practice by leaving the link as the system default (to open within the existing tab) Links
Copy and paste bullets or numbered lists from Word Use the bullet and numbered list functions within the web editor Lists
Use different formatting from the examples provided in your designs (this includes colours and fonts, or putting anything format related in the Source code) Use the formats available in the web editor and displayed in the Content page of the demo area on your site.  If you are unsure, or need a new format, contact Frank Support Formatting
Use acronyms or abbreviations Write words out in full so everyone can understand them Content writing
Write lengthy, wordy content Write shorter content that is easy to digest.  Use sections, lists and tables to break information up.   Content writing
