इस सवाल का पहले से ही एक उत्तर है: < / P>

  • 6 उत्तर

    मैंने एक के माध्यम से देखा है कई ऊर्ध्वाधर केंद्रित तकनीकों में से बहुत सारे हैं, लेकिन कोई भी मेरे लिए काम नहीं कर रहा है - मुख्यतः क्योंकि मैं एक निश्चित स्थित डिवा का उपयोग कर रहा हूं। 

      & lt; div id = "lightbox" & gt; & Lt; div id = "lightboxImgContainer" & gt; & Lt; img src = "'+ image_href +'" / & gt; & Lt; / div & gt; & Lt; / div & gt; # लाइटबॉक्स {स्थिति: तय; शीर्ष: 0; बाएं: 0; चौड़ाई: 100%; ऊंचाई: 100%; पृष्ठभूमि: #ffffff; text-align: केंद्र; z- सूचकांक: 4; कुछ भी डिस्प्ले मत करो; } #lightboxImgContainer {display: table-cell; ऊर्ध्वाधर- align: मध्यम; अधिकतम ऊँचाई: 100%; अधिकतम-चौड़ाई: 100%; text-align: केंद्र; } # लाइटबॉक्स आईएमजी {अधिकतम-ऊंचाई: 100%; अधिकतम-चौड़ाई: 100%; }   
     इसके अलावा, क्या मैं एकमात्र व्यक्ति हूँ जो सोचता है कि यह एक मजाक है जो ऊर्ध्वाधर संरेखण क्षैतिज संरेखण के समान सरल नहीं है? मैंने इस पर बहुत ज्यादा समय बिताया है जो एक सामान्य कार्य होना चाहिए।   
     
     
     सबसे आसान इसे पृष्ठभूमि छवि के रूप में सेट करना है:  
      #lightbox {background: url (myimage.jpg) नहीं-दोहराने केंद्र केंद्र}   
     वैकल्पिक रूप से, आप flexbox का उपयोग कर सकते हैं यदि आप  
      #lightbox {display: flex; } # लाइटबॉक्स आईएमजी {align-items: center; }

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...
