html - How to hide part of image if the image length is too long for mobile devices -


When the image is too long, I am having trouble changing the image again. I have a Lider for my mobile website Most of the images are now in width, so they are mapped properly and my content does not go too far. But when the image is long in height, I want to see a padding in the picture and only the middle part of the image should be visible 

  & lt; div id = "ok" & gt; & Lt; Img src = "img.jpg" & gt; & Lt; / Div & gt;   
 CSS: # OK {width: auto; Height: 400px; Overflow: hidden; } # Oak img {width: 200px; Height: auto; }  
 The above code is an example for an image 200px wide and the height is limited to 400px. If the image is overflow or overseed, then the area is hidden which is overflow.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
