html - CSS button hover background style child -


when hovers on button img element inside it, should have red background color.

<button class="btn-img">     <img src="http://upload.wikimedia.org/wikipedia/en/thumb/2/2a/burj_al_arab,_dubai,_by_joi_ito_dec2007.jpg/220px-burj_al_arab,_dubai,_by_joi_ito_dec2007.jpg" alt="dubai" /> </button>   .btn-img {     display: block;     width: 160px;     height: 120px;     margin: 0;     padding: 0;     border: 0;     cursor: pointer; }  .btn-img:hover {     background-color: red; }  .btn-img:hover img {     background-color: blue; }

http://jsfiddle.net/28qem/

is possible? because of button element, because if child inside div has background color, , parent background color changes, overwrites children's background color.

here 1 possible way of getting effect want:

<button class="btn-img">     <div class="img-wrap">     <img src="image_name.jpg" />     </div> </button>

and css might like:

.btn-img {     display: block;     margin: 0;     padding: 0;     border: 0;     cursor: pointer;     background-color: white;     outline: 1px dotted blue; } .btn-img .img-wrap {     margin: 10px; }  .btn-img img {     display: block; }  .btn-img:hover .img-wrap {     background-color: black; }  .btn-img:hover img {     opacity: 0.8; }

how works

wrap image <div> can control margins , padding more accurately , give hook control background color behind image without having color spill outside of image itself.

when trigger .btn-img:hover, change background color of div.img-wrap black , change opacity of image 0.8. has effect of darkening image.

you can experiment effect trying different background colors image wrap element , degree of opacity.

i think might work in ie7, give try.

and way...

if wrapping image link use javascript type of zoom-view effect (highslider example), can replace <div class="img-wrap"> simple <a> tag , set display: block.

keep in mind...

browsers tend style <button> differently other inline elements <span>, properties margin , padding may behave bit differently might expect.

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 ...
