Plan and done for May-22-2017

What will I learn today?

1. Make menu hide only on tablet and desktop versions or add input-label to hide JS-function.
2. Fix quirks in Safari: icons have became too small, everything become a mess on a wide screen.
3. Fix a masthead height on resolution wider 640px.
4. Fix an offer body text align for the gift message - now it aligns to center on resolutions less than 570.
5. Build additional pages - hotels, impression, blog.
6. Style the form on impression page.
7. Dive into JS.

Done

7. Returning to my last question from the day before - why the syntax ++array[element] || 1: I've found the answer here - https://en.wikipedia.org/wiki/Short-circuit_evaluation. It's common aspect of programming and for JS it works like this:

   In loosely typed languages that have more than the two truth-values True and False, short-circuit operators may return the last evaluated subexpression, so that x Sor y and x Sand y are equivalent to if x then x else y and if x then y else x respectively (without evaluating x twice).

   And from another source (http://www.grauw.nl/blog/entry/510) here is more clear explanation:

   ...if the first operand evaluates to false, the second operand is never evaluated because the result would always be false. Similarly, for || if the result of the first operand is true, the second operand is never operated.

   For my question it should be applied as: while we've got undefined for the first part of or we choose the second part of the statement - 1.

Spontaneous. To make an inline code block in rst (reStructuredText) use :code:`something` notation. Look here - https://stackoverflow.com/a/12365251 - for more.
