Focusing on code (HTML, CSS, PHP, and JS) and content structure on cpl.orgQuestions strictly on grammar and usage are not covered in this guide; they are covered in Cleveland Public Library Style Guide at XXXXX, see Laura A. Walter for details.
This guide is designed to:
- provide consistency in design, quality, and structure of our code and content
- ensure that best practices for content and code structure are being used
Last updated 2021-05-05
Following the principles in our strategic plan, we:
- “provide equal access to a vast range of information and resources.”
- “actively embrace new ways to adapt the Library to the changing
needs of the people we serve.”
- Don’t use new technology for the sake of using it but only if it helps to serve our patrons and that they want it.
- “offer collections that are of interest to our users in ways
that are most convenient for them.”
- Ensuring patrons have access to content through means that are accessible to them.
- “are passionate about providing library service to our community.”
- “conduct all interactions with respect and can be counted on to do the right thing in a fair and equitable manner.”
- Ensure that you have enough contrast (4.5 or greater) between the color of text and the background. This tool from Eightshapes lets you compare foreground and background colors and their levels of contrast
- Exception: Text that is a part of a brand name or logo does not have any contrast requirement <
- Do not use color as the only indication of a text’s importance or significance.
- For deciding which colors to use, review our Graphic Design Brand Guidelines(page 24).
to organize:When using instructive language on the website, do not solely rely on direction or color. E.G. Do not say “Click on the yellow button” or “Complete the form above”; instead say “select the registration button”.
Typeface:– Use Proxima Nova (TO BE UPDATED)
Content and Links:
- Use the proper HTML elements. Mozilla’s MDN on elements has a comprehensive review.
- Use the heading element to to structure your content.
- Do not skip headings (e.g. h1 to h3) (source Mozilla MDN Heading Element)
- Do not use
<b>as headings or to creating sections; use a heading.
- Use the <ol> tag for ordered lists and <ul> for unordered lists. Do not write 1. 2. 3, to make a list
Links:Do not use “Click Here” or other directional language for URLs. For example: Not:
Click here for more details on the library's policy for room reservations. Instead:
Read the library's room reservation policy for additional details.Do not include the verb as a part of the URL text; according to Penn State’s Links Guide. The Nielsen Group also has more do’s and don’ts. Gian Wild also has additional contexts and criticisms of WCAG for links.
Avoid Using ‘Learn More’
– There are a couple different options: you could include retain the Learn More and add descriptive keywords (e.g. “Learn more about CPL’s partnerships with CMSD” )Nielsen Norman Group’s Alternatives to Learn More links has suggestions how to avoid ‘read more’ type links.
Alt Tags:Appropriate alternative text depends heavily on the image’s context.
- ALT tags provides the content and the function of the image.
- The alt tag for a particular image is dependent on the context. If the same image is used in 2 different places; each image’s alt-text may be different since because its alt-text depends on its context.
- Do not include “photo of” or “image of” in beginning of your alt-text
- If no alt-text needed, leave the alt-text field blank
https://www.cpl.orgfor the url. – All urls on cpl.org should be accessible if you omit www. However, remember some of our patrons do not know that it’s not necessary to begin a url with www, so you can use your best judgement based on spacing whether to include www). – a trailing slash at the end of the url is not necessary – If you’re instructing people to download a specific file and there’s a file extension at the end of the url (e.g. https://cpl.org/application-to-cards.pdf); do not include a trailing slash. – Write urls in all lower-case letters.
CPL.ORG– If you’re mentioning a file with an extension (e.g. https://cpl.org/application-to-cards.pdf), remember the file name is case sensitive and the url must match the file name. – in file names and page names, omit articles (a, an, the) and conjunctions (for, but, of) unless it is a part of the CPL brand (e.g. CLE FOR GOOD) – (More to come regarding proper file names for our digital assets) – use present tense of verbs; no gerunds (e.g. /make-crafts instead of /making-crafts) – separate words by a hyphen instead of underscores (do not use spaces in paths and file names)
linking to a URL on the same page:If you need to link to a specific section or part a page rather than the entire page, customize the following two snippets:
Later selectionshas directions how to obtain recent obituaries.
Recent ObituariesYou can swap out the div element with h3, li, or other html elements
Content formats– Make content as HTML instead of PDFs or DOCS (see guides by the US Federal government’s 18F , University of Waterloo’s Web Resources, and the UK’s Government Digital Service.) Why:
- Text on pdfs is optimized so that pdfs so that is displayed only in one format: print.
- Browsers don’t natively render them;
- PDFs do not automatically readjust the text size to the size of the screen, forcing users to scroll in multiple directions and lose their place.
Our WordPress theme:Ask Will Skora for assistance; directions at https://gitlab.com/cpl/tempera-nocopyrt
Code style/structure:It’s a combination of best practices from WordPress, U.S. Web Design Standards, the Vox Accesssibility Guide, 18F Front End Guide, the NYPL Design Toolkit, 10up’s Best Practices, and more.
CSS:Please read WordPress’ CSS standards. 18F’s Front-End Guide also has good rules regarding naming. Creating new selectors: – use
-to separate words when specifying selectors e.g. “continue-reading-link”); – A handful of selectors in our parent theme and gravityforms already use underscores. – We’re transitioning to more BEM-based naming schema and code structure – Name components by using singular nouns (e.g. cpl-button; NOT cpl-buttons) – Use Semantic Naming – name your selector by describing its function or the role that it serves; not by its appearance. For example, don’t include a color in the name because the color may change later. Try not to name it based on the content since we may also use the selector in other contexts in the future (bad: purple-writers-and-readers-card; better: writers-and-readers-card; even better: card-event; best: ? ) – Use one selector and one declaration per line * Many components are prefixed with cpl- to avoid conflicts with the parent theme and any plugins. Generally prepend
cplto the beginning of your new selector. e.g. “cpl-button-action” * for elements of within a block, use __ to separate a new component; * for a modifier, kind of the block; use — to distinguish it. Be liberal with commenting. Ask yourself: Am I going to reuse this code on another page or post? If yes, I strongly encourage you to ask Will to make a css rule in the stylesheet; Do not use
style="") within the browser.
PHP:Be consistent; follow WordPress’ PHP coding standards Single quotes unless you need to escape. Use the WordPress-Core coding standards
ACF field names:
- separate by underscores
- all lower case
- describe what the data is inside, not what it’s used for (because it could be reused in the future);
Patterns/components:Patterns are pieces of code that can be reused across different pages to create a consistent design and minimize time to recreate content. The City of Boston issued a Press Release why they created a pattern library. These are generally prefixed by
Buttons:(in this instance, we’re using this often muddled term to describe 2 distinct actions: a very prominent link or a button. Use the
buttonelement (traditional sense of toggling statuses, changing a feature on a page and DOES NOT direct a user to a new page). Use the
aelement for prominent links; there’s also the input element that is used for submitting forms. cpl-button – general button. Use cpl-button as well as one of the other following classes: cpl-button-action – yellow, used for action (e.g. Register for an event, submit a form); typically will drive the user to a new site or complete an action that will direct them to a new page. cpl-button-status (the buttons have not yet been updated to represent the updated BEM naming status) e.g.: Access Lynda.com
Alerts are used to signify a particular scenario that is typically unique to the user or to that page.
Developed as a group block

AnnouncementsAnnouncements are a custom post type, very similar to an alert but are not contextual to a specific page; they are applicable announcement criteria: Used to announce time-sensitive closures, news, and emergencies.
- no ‘title’ or lead-in
- no programming announcements.
- – uses a paragraph block;
- – the styling lives outside of the block editor (for now);
- – no need to make this a custom block just yet A smaller Alert! (courtesy of fontawesome)
Main heading – H1
Each page must have a H1 and in nearly all cases on our site, they are the title of the page/post and are automatically generated by WordPress.
