Since these two paragraphs sit on a blue background, they should have
white text. But this was getting overridden when the `govuk-body` class
was added in a previous commit, and the paragraphs appeared with black
text.
Previously these paragraphs were inheriting their colour from a parent
element. But a class applied directly to the element is more specific.
So this commit fixes the problem by being more specific again, by
applying the colour to the element, in the context of it’s parent’s
class.
International letters aren’t sent by first or second class post. In
keeping with the little touch of skeumorphism, let’s label them with the
commonly recognised marker of international mail instead.
Includes:
1. changes to make NestedFieldMixin work
with new fields and CSS for nested checkboxes
2. adds custom version of GOVUK checkboxes
component to allow us to:
- add classes to elements currently inaccessible
- wrap the checkboxes in a list
- add child checkboxes to each checkbox (making
tree structures possible through recursion
Change 2. should be pushed upstream to the GOVUK
Design System as a proposal for changes to the
GOVUK Checkboxes component.
Allows checkboxes to be collapsed so they take up
less space in the page. The collapsed state
includes a live summary tracking which of them are
selected.
Includes changes to the JS for collapsible
checkboxes to make it work with the GOVUK
Checkboxes component HTML.
At the moment the first AJAX call is triggered as soon as the page
loads. We then look at its response time to work out how long to wait
until making the next call.
This isn’t great because:
- stuff is unlikely to have changed straight away, so it’s a waste of a
call
- while the DOM is being updated it seems to introduce a delay in
clicks on links, which is either more pronounced or more noticeable
when it’s happening straight away, making the UI feel less snappy
I chose a value of 2 seconds as a rough proxy for the minimum time we’d
expect to see a notification go from created to delivered. Median
time-to-delivered was 2.9 seconds when we analysed it for
https://github.com/alphagov/notifications-admin/pull/2974#discussion_r286101286
By default our AJAX calls were 2 seconds. Then they were 5 seconds
because someone reckoned 2 seconds was putting too much load on the
system. Then we made them 10 seconds while we were having an incident.
Then we made them 20 seconds for the heaviest pages, but back to 5
seconds or 2 seconds for the rest of the pages.
This is not a good situation because:
- it slows all services down equally, no matter how much traffic they
have, or which features they have switched on
- it slows everything down by the same amount, no matter how much load
the platform is under
- the values are set based on our worst performance, until we manually
remember to switch them back
- we spend time during incidents deploying changes to slow down the
dashboard refresh time because it’s a nothing-to-lose change that
might relieve some symptoms, when we could be spending time digging
into the underlying cause
This pull request makes the Javascript smarter about how long it waits
until it makes another AJAX call. It bases the delay on how long the
server takes to respond (as a proxy for how much load the server is
under).
It’s based on the square root of the response time, so is more sensitive
to slow downs early on, and less sensitive to slow downs later on. This
helps us give a more pronounced difference in delay between an AJAX call
that is fast (for example the page for a single notification) and one
that is slow (for example a dashboard for a service with lots of
traffic).
*Some examples of what this would mean for various pages*
Page | Response time | Wait until next AJAX call
---|---|---
Check a reply to address | 130ms | 1,850ms
Brand new service dashboard | 229ms | 2,783ms
HM Passport Office dashboard | 634ms | 5,294ms
NHS Coronavirus Service dashboard | 779ms | 5,977ms
_Example of the kind of slowness we’ve seen during an incident_ | 6,000ms | 18,364ms
GOV.UK email dashboard | `HTTP 504` | 😬
24px with 19px is what we use on the uploads page. On notifications page
we use 19px with 16px.
There’s some loose idea that the bigger size is for items that contain
other items.
This also increases the line height for recipients of PDF letters to
make things line up.
Replaced `$gutter` and similar variables such as `$gutter-half` with the
`govuk-spacing()` static spacing function. This uses `govuk-spacing()`
instead of `$govuk-gutter` because `$govuk-gutter` should only be used
for the gaps in between grid columns and we were mostly using `$gutter`
to add more space around elements.
There are other places in the SCSS files where we had hardcoded a
measurement in px which could be replaced with `govuk-spacing`, but this
commit only replaces the existing uses of `$gutter`.
We had 7 classes in _grids.scss named `.column-...` which were being
used to give a certain column width. These worked by using `@include
grid column()`, which is now deprecated.
`.column-whole` and `.column-three-quarters` can be removed and replaced
with `govuk-grid-column-full` and `govuk-grid-column-three-quarters`
respectively. The other column classes don't have a direct replacment in
GOV.UK Frontend. To get round this, we overwrite the `$govuk-grid-width`
SASS map in `extensions.scss` to add in extra widths, then use this with
the `govuk-grid-column` mixin to create new classes in for our custom
widths in `_grids.scss`
Stopped using `#content` on the product page - this was from GOV.UK elements.
Also removed the `override-elements-content` class since the page looks
the same without it.
Includes:
- make 'remove team member' link, on edit member
permissions page, destructive
- convert missed links on /features pages
- convert missed links on /using-notify/guidance and sub pages
- give links in browse-lists back their size and
weight (needed for lists of live and trial
services on Platform Admin)
- give links on Platform Admin inbound numbers
page back their size and weight
- update links in JS tests
Giving all links the GOVUK Frontend classes, and
the new `govuk-link--destructive` class, means
some styles are already applied.
This strips out those styles.
Note: there's still a good amount of styling, most
of which is to make the focus styles specific to
the space the link is in. These will need
reviewing when GOVUK Frontend is bumped past
version 3 as this brings in new focus styles.
Converts links in the following:
- the page-footer component
- the table component
- the browse-list component
- the notification status, when reporting failures
- validation messaging in the whitelist page
Includes:
- removing all styling of those links
outside of GOV.UK Frontend (except for a few fixes
due to their interaction with our design)
- bringing together some duplicate styles into one
block
- changing how links are marked as selected, now
they have multiple classes
Fix Sass-lint error in navigation.scss
This colour is used in a few places so worth
making into its own block and classes.
Note: this establishes a
`app/assets/stylesheets/local` folder for any Sass
files whose names clash with files from vendored
libraries.
`_typography.scss` already exists in GOV.UK
Elements Sass.
This will no longer be needed when GOV.UK Elements
is gone and GOV.UK Frontend is at version 3, where
all its folders are in a `govuk` folder.
Making all links GOV.UK Frontend styled means some
will sit in content that doesn't use the GOV.UK
Frontend font styles yet.
This applies the font-smoothing that comes with
those styles to all text so links do not look out
of place on browsers that support it.
Note: font-smoothing was part of the GOV.UK
Template styles which have now been removed:
