Pinterest splash page in twitter bootstrap -


checkout pinterest's splash page - **(make sure logged out of account or wont see splash page.) image of macbook @ bottom, it's responsive , shrinks , expands depending on size of broweser window.

silly question... how it? , how can done using twitter bootstrap?

if @ <script> blocks on page, can see how it's done. it's resize listener. here's simplified version:

var htaboveimage = $content.height(),     naturalimageht = 450,     padding = 150,     minimageht = 100;  var changefunc = function() {     var windowht = $window.height();     var imageht = math.min(                       math.max(windowht - htaboveimage - padding, minimageht)                       naturalimageht,                   );     $image.height(imageht); }; changefunc(); $(window).on("resize", changefunc);

there's no need update width too, because <img>s automatically resize proportionately when size 1 dimension in css. full code on pinterest updates padding on content above image keep vertically centered.

by way: chrome's developer tools friend when comes questions this! making careful use of these tools, takes minute see what's going on:

  1. right-click image > inspect element
  2. resize window , notice there's explicit height in px being set on tag, updating continuously. must done js. who's setting it?
  3. right-click tag > break on... > attributes modifications
  4. resize window again , hit breakpoint
  5. top of call stack buried in minified jquery code – generic code setting css property. what's highest non-jquery piece of code on stack?
  6. there's code!

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
