Notes on lines these pages already print.
Five language labels
The language menu on the front page has five entries, in this order: deutsche, english, español, русский, 中文. deutsche and english are lowercase. español keeps the accent. русский and 中文 are not transliterated on the page. Each entry is a link, and each has a flag image.
The five front pages still put London in the heading. The note on the English front page quotes the English title. The other four titles are below.
The five words and the five files
deutsche links to /de. The image is /imgs/flags/rectangle-simple-80x60/de.png. The alt and the title are deutsche. The visible word is deutsche, not Deutsch and not German.
english links to /en. The image is gb.png, in the same folder. The alt is english. The file is gb, not a separate word England, and not uk. The path is /en.
español links to /es. The image is es.png. The alt is español, with the accent. The path is /es, without the accent.
русский links to /ru. The image is ru.png. 中文 links to /zh. The image is cn.png. The path says zh. The file says cn. Those two codes are not the same letters, and the page prints both, one in the address and one in the image name. The note on unit paths is a similar case of a short code sitting in an address.
deutsche is lowercase. english is lowercase. español keeps the accent. The path /es does not.
中文 is the menu word, and the path under it is /zh.
Five titles
English, on / and on /en: Weather Atlas | United Kingdom weather forecast and Climate information. Climate is capitalised.
German, on /de: Weather Atlas | Vereinigtes Königreich die Wettervorhersage und Klimadaten. The word die sits between the country name and Wettervorhersage. The page prints it there.
Spanish, on /es: Weather Atlas | Reino Unido previsión meteorológica e información climática. previsión has the accent. The country name is Reino Unido.
Russian, on /ru: Weather Atlas | Великобритания Прогноз погоды и Климатические данные. Chinese, on /zh: Weather Atlas | 英国 天气预报和气候信息。 The Chinese title ends with a full-width full stop. The English title does not end with a full stop. The note on place titles uses the long English city title, which is a different pattern from these five front-page titles.
German prints die between Vereinigtes Königreich and Wettervorhersage. Spanish prints previsión with an accent. Chinese ends with a full-width stop. English capitalises Climate and has no stop.
None of the five titles names a second city. London, Londres, Лондон and 伦敦 stay in the heading under the title, not inside the title line itself. The German title also prints the word die, which the English title does not.
Five headings, one city
The English heading is Weather forecast, then London, United Kingdom, with GB hidden in the markup.
The German heading is Die Wettervorhersage, then London, Vereinigtes Königreich. London is not translated. The country name is.
The Spanish heading is Pronóstico del tiempo, then Londres, Reino Unido. Here the city is Londres, not London.
The Russian heading is Прогноз погоды, then Лондон, Великобритания. The Chinese heading is 天气预报, then 伦敦, 英国. Each of those is the front page of that language. None of them names a different city in that heading slot. The English and German pages say London. The Spanish page says Londres. The Russian and Chinese pages use their own forms of the same name.
English and German say London. Spanish says Londres. Russian says Лондон. Chinese says 伦敦. The slot is the same slot on each front page.
English and German leave the city as London. Spanish writes Londres. Russian writes Лондон. Chinese writes 伦敦. The heading slot does not move, and the country follows the city on each of the five pages. Vereinigtes Königreich, Reino Unido, Великобритания and 英国 are the other country forms on those pages.
hreflang, six addresses
The English front page lists alternate links. / is hreflang x-default. /de is de. /en is en. /es is es. /ru is ru. /zh is zh. That is six addresses: the default and the five languages. / and /en share a title. They are still two hreflang values, x-default and en.
The flag for english is gb.png, while the hreflang is en. The flag for 中文 is cn.png, while the hreflang is zh. The page does not collapse those pairs into one code.
deutsche, english, español, русский and 中文 are the visible menu words. The hreflang codes are the shorter list de, en, es, ru, zh. Both lists are on the page.
The menu sits under the word Languages. The five words are not translated into English inside the menu, except that english is itself the English word, in lowercase.
x-default is the front page /. en is /en. They share a title and remain two hreflang values. gb.png is the English flag file. cn.png is the Chinese flag file, on the path /zh.
Those two files stay distinct.
What does not change with the language
The author meta on the English page is Yu Media Group d.o.o. The footer copyright © 2002-2018 is on that English page. This note does not claim those two strings are translated on /de or /zh. It claims the titles and the headings above, which were read on each front page.
The location count United Kingdom: 13.512 is an English line. The note on that count does not translate 13.512 into the other four pages.
Search on the English page says United Kingdom - search location. That placeholder is not the language menu. The language menu is the five words and the five flags.
Five labels, five paths, five flag files, and two mismatches between file and path: gb.png with /en, and cn.png with /zh. The headings still name London, in the wording each page uses.
The author meta and the copyright line are quoted from the English page only. The five titles and five headings were read on the five front pages.
London remains the city named in each of those headings.
