html - Centering an image that is in an anchor tag -


I have an image in anchor tag, and I need to focus it.

I have managed to use this technique to do this so that I have just been walking in the Dome Inspector:

uses it: 

 < code> Display: Table; Margin 0 auto;   
 I tried to use it:  
  display: block; Margin: 0 auto; Width: (?) Px;   
 But I came to know that it was not actually centering it until I got very confused with width which is not really very good because anchor tag width does not work too (IMO) was originally using a margin-left  
 Curious that you have used any of these before or have got a better technique in terms of performance: Table 7 is not supported and back   
 
 
 You can use  text-align: center;  #container at the inside of the center elements. Example:

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...
