43 /* General Page Layout and Formatting
44 * ==================================
47 { /* Default style, applicable to all normal page content; favour

49 * text colour, on a pale blue-grey background; centre text within

58 * subtitle respectively; thus, h3 becomes the first level
59 * available for section headings. Preserve the browser's
60 * default h3 styling, but pull the following paragraph a
63 margin-bottom: -0.2em;

85 * inter-paragraph spacing...

90 { /* ...while maintaining a deeper space before the first in any
91 * free-standing text division.
96 { /* Also maintain a deeper space between paragraph text and any
97 * intervening horizontal rule.
102 { /* Keep any unordered list, ordered list, or defining list
103 * closer to any immediately preceding paragraph text than
104 * normal inter-paragraph spacing, but separated slightly
105 * more than single-line text spacing.

128 * definition list of the "no-indent" class.
134 /* Fixed Position Page Header Block Formatting
135 * ===========================================

139 * at the top of the viewport, across its full width, and variable
140 * page content will scroll below it.
142 position: fixed; z-index: 50; top: 0; width: 100%; height: 70px;

154 * logo, for display of centred mid-blue-grey text, in Google's

171 * block; implemented as an unordered list, without bullet marks,
172 * it is placed centrally, with its top set at two logical pixel
173 * heights below the top level (h1) heading text.
175 list-style: none; margin-top: 2px;
178 { /* Each navigation tab is represented by a list item, arranged
179 * within an inline-block display, (hence laid out horizontally).
180 * Each tab is styled to give the appearance of a row of filing
181 * cabinet tabs, with the entire row occupying 99% of available
182 * display width, (after deduction of the 15% reserved for the
183 * logo); hence the width of each tab (currently there are 5)
184 * becomes (99 - 15) / 5 = 16.8%.

200 * of their respective tabs, while preserving the text colour
201 * theme of the page header block.

207 /* General Page Content Formatting
208 * ===============================
211 { /* Set the page content to begin immediately below the reserved
212 * space for the fixed page header; (it may subsequently scroll,
213 * to be occluded behind the header).
215 position: absolute; top: 70px;
216 text-align: justify; padding: 0 3% 1.5em;
219 { /* Nominally placed at the top of the page content region, we
220 * allow for a "masthead" region, offset from the main content
221 * by one vertical em-space, in which the page title, and any
222 * desired page subtitle, may be placed.
227 { /* Within the "masthead" region, the page title will be set as
228 * a level one heading, with no space below.
233 { /* Similarly, if present, the page subtitle will be set as a
234 * level two heading, at default size for such headings, but
235 * with no emboldening.
237 margin: 0; padding-top: 1px; font-weight: normal;
240 { /* On page overlays, we use a definition list to specify the
241 * page title, and subtitle, which are to be propagated to the
242 * masthead section within the page content; the content of the
243 * definition list, itself, should not be directly visible.
248 { /* The masthead section is separated from the remaining page
249 * content, by a horizontal rule; to keep white space balanced,
250 * above and below this rule, when it is immediately followed
251 * by a paragraph, with no intervening heading, we need to
252 * explicitly adjust the paragraph margin.
258 /* Subsection Reference Positioning Relative to Page Header
259 * ========================================================
262 { /* Any internal page reference will be positioned at the same
263 * vertical offset, within the viewport, as the top of the page
264 * header block. Thus, any text which appears within the upper
265 * 70px of the subsection division will be hidden behind the
266 * header block; adjust the alignment of the target element,
267 * such that its top margin overlaps the lower region of the
268 * preceding element, by the depth of the header block, then
269 * pad it, to push the content downward, into the viewport.
271 margin-top: -70px; padding-top: 70px;
274 { /* When an overlapped division follows a horizontal rule, we
275 * need to adjust its position upward, to allow for the blank
276 * space in the bottom margin of the rule element.
278 margin-top: calc( -70px - 0.6em );
282 /* Supplementary Formatting for Sections with Numbered Headings
283 * ============================================================
286 { /* On starting any new numbered section division, reset the
287 * heading serial number sequence, and establish a suitable
288 * space at the top of the display region.
290 counter-reset: h3-number;
293 .h3-numbered h3::before

295 * number, and prefix it to the heading text.
