Makes sure the tabindex we add for focusing is
removed.
Also removes the outer fieldset from the radios
for new templates. We don't wrap form buttons in
fieldsets anywhere else and it doesn't add any
useful semantics to the form.
Adds some extra styles so <fieldset>'s show as
focused when they are.
Also includes replacement of `overflow: hidden` on
sticky elements with a clearfix. hiding overflow
clips the outline and the clearfix can be used for
containing any floats instead. (I'm assuming that's
why it was set here.)
When mode === 'dialog', sticky elements are
stacked so we need to apply the box shadow to the
top (when sticking to the bottom edge) and bottom
(when sticking to the top edge) elements in the
stack.
From what I can see, we need the version of
`nth-child` that supports targeting by selector.
As of this date, support for this is only in
Safari:
https://caniuse.com/#feat=css-nth-child-of
Until we can use this version of `nth-child`, we
need to use JS to apply the styles.
We want a mode for when a single task is shared
between all sticky elements on the page and that
task has the highest priority on the page. In that
case:
- they should stack together into a single block,
attached to the top/bottom of the viewport
- that block should adjust to the vertical space
available
This should also adjust to the height of the
viewport, dropping whatever elements that don't
fit back into the page flow. When this happens, we
scroll the page so all the parts of the dialog are
seen together at the start of the task.
This is better because it saves vertical space for the contents of the
pop-up menu.
This commit also adds some padding to the cancel and clear buttons, to
make them easier targets to hit.
Added a link to cancel letters from the letter notification pages if the
letter is still able to be cancelled. Clicking on this link will show a
confirmation box, and will then cancel the letter if the user confirms.
This makes its positioning consistent with the previous page in the
one-off sending journey.
It gives us more space to put information about the status of the letter
above the preview of the letter.
We’ve moved away from using the expand/collapse pattern on the page
where you click ‘send’. Instead we’re putting the send button in the
sticky footer.
So it’s a bit jarring to still have the expand/collapse on the page you
see after you’ve sent an email. This commit replaces it with the sticky
footer as well.
This is only relevant for emails because:
1. Text messages are generally short enough to fit on the screen
2. We don’t show the status of letters because they don’t really change
Detach all methods from sticky reference so they
can be attached to different objects.
Split sticky into stickAtTop and stickAtBottom and
make new versions of all methods and properties
specific to stickAtBottom.
Add CSS for stickAtBottom and call on load
We weren’t calculating the height quite right; we were trying to
compensate for something that should have been compensated for in the
`stick-at-top-when-scrolling` code.
Add the 5px to the shim there is required because we’re adding it to the
element that the shim in replacing.
There were three problems with showing tables fullscreen:
- it was over-optimised for very big spreadsheets, whereas most users
will only have a few columns in their files
- it was jarring to go from full screen and back to the normal layout
- it was a bit change for existing users, where we prefer incremental
changes that make things better without disrupting people’s work
(where possible)
So this commit changes the big table to scroll horizontally in the page,
not take up the full width of the page.
From the fullscreen table it keeps:
- the shimming method to keep the horizontal scrollbar at the bottom of
the screen at all times
It introduces some more refinements to make it nicer to use:
- fixing the first column, so you always know what row you’re on
- adding shadows indicate where there is content that’s scrolled outside
the edges of the container
Normally, fixed position elements are positioned at `top: 0`.
The code that stops them from overlapping the footer does so by:
- setting the position to absolulte
- setting `top` to a calculated value (eg `1500px`) which makes it sit
above the footer
The problem is caused because we’re animating `top`, so when scrolling
back up the page elements are getting animated from `1500px` to `0px`,
ie flying up from the bottom of the screen.
The transition between something being static in the page and fixed to
the top of the viewport is a bit jarring.
This commit adds a bit of animation so that, as elements become fixed,
they appear to catch up with the scrolling of the page.
You might need to scroll this page quite a lot to see where a
placeholder appears in your template – especially if you have a long
email or letter.
One of the things I’m trying to stop happening so much is a lot of
scrolling back and forth. This would happen if you were scrolling down
to see the placeholder, then back up to fill in its value.
So this commit makes the textbox ‘sticky’, ie it always stays at the top
of the viewport, even when you scroll down. This lets you see the
placeholder and the textbox side by side, no matter how long the
template is.
The code to do this mostly comes from the GOV.UK Frontend Toolkit
(documented here: d9489a9870/docs/javascript.md (stick-at-top-when-scrolling)).
I had to add some extra CSS to make it look good when it overlaps the
content of the page, which the GOV.UK Frontend Toolkit implementation
doesn’t really anticipate.
