Plan step 36 audit. field.css's trailing button (clear, copy, reveal) scales its state layer with the field's own icon size and doubles it as the touch target, which the foundation's fixed-size interaction classes cannot draw, and the hook stays data-md-field-button rather than a class because datepicker and timepicker, not yet rewritten, still select it — so it keeps its own declarations. It never hid the layer on a disabled button, unlike every rewritten component's copy; it now does.

/*
|
|
* M3's text fields — the chrome every form control here shares: outlined (the default) and filled.
|
|
*
|
|
* The states are selectors rather than classes: whether the label rests in the field or floats is a
|
|
* question about the control's value and focus, and `:has()` asks it without JavaScript, so it is
|
|
* right before Alpine starts, in a test, and after a Livewire morph rewrites the value underneath.
|
|
*
|
|
* The outlined field's notch is MUI's technique: a `<fieldset>` draws the outline and a hidden
|
|
* `<legend>`, carrying the label at its floated size, cuts the gap the label sits in, so the gap is
|
|
* right on any background. The filled field has no outline: a surface-container-highest box with
|
|
* extra-small top corners and an active indicator line, the label floating inside it
|
|
* (FilledTextFieldTokens / OutlinedTextFieldTokens, androidx Compose Material 3, Apache-2.0): 56px
|
|
* tall, 16px padding, 24px icons 16px from the text, the label in body-small once it floats.
|
|
* The `sm` (40px) and `xs` (32px) sizes are this package's, for an unlabelled field in a toolbar.
|
|
* Disabled is on-surface at M3's 38% content and 12% container opacities (tokens/state.css); the
|
|
* filled field's disabled container is on-surface at 4%, FilledTextFieldTokens'
|
|
* DisabledContainerOpacity, which has no system token.
|
|
*
|
|
* Anatomy (resources/views/components/field.blade.php):
|
|
*
|
|
* [data-md-field] the whole thing; `class` from the call site lands here;
|
|
* data-md-variant, data-md-size, data-md-invalid, data-md-floated,
|
|
* data-md-mono, data-md-full, data-md-readonly
|
|
* [data-md-field-box] the 56px row: icon, prefix, control, suffix, trailing
|
|
* [data-md-field-icon] the leading icon
|
|
* [data-md-field-affix] a prefix or suffix beside the value
|
|
* [data-md-field-control] the <input>, <select> or <textarea>
|
|
* [data-md-field-trailing] what ends the row; [data-md-field-error] is the error icon M3 asks
|
|
* for as the error state's second indicator; [data-md-field-button]
|
|
* a trailing icon button (clear, copy, reveal, open a picker)
|
|
* [data-md-field-outline] the fieldset and its legend (the filled field's indicator line)
|
|
* [data-md-field-label] the visible label
|
|
* [data-md-field-support-row] the row under the field
|
|
* [data-md-field-support] the hint, or the error in its place
|
|
* [data-md-field-counter] M3's character counter, `n/max`, at the end of that row
|
|
*
|
|
* A select's open list is not part of the field: it is the dropdown menu in components/menu.css.

/* M3 § Text Fields, Behaviour: "compact breakpoints can let a text field span full width;
|
|
* medium/expanded should bound it with flexible margins/other containers — never let it span the
|
|
* full width of a large screen." The site names no number, so 40rem is this package's: it is
|
|
* under half the `large` breakpoint's 1200px, a little over half the `expanded` one's, and holds
|
|
* about the 70 characters body-large reads best at — a measure of text, so it is in rem and grows
|
|
* with the text. It is a ceiling, not a width — a narrower pane still gets a narrower field. A
|
|
* width rule from the call site beats it, because an application's CSS and a utility both
|
|
* outrank this layer, and `full` takes it off for a field that really is the width of its pane (a
|
|
* search-and-filter row, an editor). Below `medium` nothing is bounded. */
