html - How do I center an image vertically within a div that is position:fixed? -


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; }

ios - Does Core Data autoupdate a many to many relationship on saving -

I have used 2 database tables and core data / NSManagedObjects in SQLite: User is user_id name group (multiple groups) Group group_id title group members (multiple users) By using core data to save a group and adding users ( Add to group) as follows: group * cordata = zero; Cordata = [NSEntityDescription insertNewObjectForEntityForName: @ Managed Object Contains in "Groups": Reference]; Request = [NSFetchRequest fetchRequestWithEntityName: @ "user"]; Request.predicate = [NSPredicate predicateWithFormat: @ "user_id =% @", user_id]; Result = [reference executeFetchRequest: request error: & amp; Error]; CoreData.group_id = group_id Cordettitle = Title [Cordata AdGroupMailersObject: [Last objections result]]; Is it right to say that core data manages a user with multiple users and groups with the code above? Yes, if the relationships are in the form of each other's inverse relationship The inverse relationships are updated automaticall...

Calling a C++ function from C# by passing a string with variable size to it -

I am calling a string with a C + code and calling from the C # code. The C ++ function is responsible for filling the string material. The following code is: C #party: var abc = new string builder (4096); // will have to change this var result = Basic methods. SignCrcFile (ABC); C ++: bool __cdecl SignCrcFile (char * abc) {... char * tempStr = "hello all"; // for example // copy it to ABC string strcpy (ABC, tempStr); Back true; } The problem is that tempStr's size in the C ++ function is dynamic (the above assignment for TempStr is only an example). In such a case, it is not a hard code that the size of ABC string is in the size of 4096 bytes on the C #. The first solution can be a solution to create 2 functions on the C ++ side to get the size of the string. Then allocate that size using StringBuilder in the C # side then use the next function to bring the entire string from C ++ to the C #. But no suggestion this may not be the most optimal way? ...
