How can I display my website in only one city?

The client only wants to be seen in one city all over the world, how can I do that, I would really appreciate your help :)

I did what you told me:

https://i.gyazo.com/5c933886ffd28e8287d803c094574009.png

and it sends me this error:

array ( 'geoplugin_request' => '::1', 'geoplugin_status' => 404, 'geoplugin_credit' => 'Some of the returned data includes GeoLite data created by MaxMind, available from http://www.maxmind.com.', 'geoplugin_city' => NULL, 'geoplugin_region' => NULL, 'geoplugin_areaCode' => NULL, 'geoplugin_dmaCode' => NULL, 'geoplugin_countryCode' => NULL, 'geoplugin_countryName' => NULL, 'geoplugin_continentCode' => NULL, 'geoplugin_latitude' => NULL, 'geoplugin_longitude' => NULL, 'geoplugin_regionCode' => NULL, 'geoplugin_regionName' => '', 'geoplugin_currencyCode' => NULL, 'geoplugin_currencySymbol' => NULL, 'geoplugin_currencySymbol_UTF8' => '', 'geoplugin_currencyConverter' => '0', )

I was using a version 3 of Bootstrap. Now that I updated to version 4 I have the following problem:

It worked for me with Bootstrap 3 ( see full page ):

.titulo {
  height: 200px;
  background: #666;
  border: 1px solid #333;
}

.dato {
  height: 100px;
  background: #666;
  border: 1px solid #333;
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />

<div class="row">
  <div class="titulo col-lg-3 col-md-4 col-sm-4">Titulo</div>

  <div class="dato col-lg-3 col-md-4 col-sm-4">1</div>
  <div class="dato col-lg-3 col-md-4 col-sm-4">2</div>
  <div class="dato col-lg-3 col-md-4 col-sm-4">3</div>
  <div class="dato col-lg-3 col-md-4 col-sm-4">4</div>
  <div class="dato col-lg-3 col-md-4 col-sm-4">5</div>
  <div class="dato col-lg-3 col-md-4 col-sm-4">6</div>
  <div class="dato col-lg-3 col-md-4 col-sm-4">7</div>
  <div class="dato col-lg-3 col-md-4 col-sm-4">8</div>
  <div class="dato col-lg-3 col-md-4 col-sm-4">9</div>
  <div class="dato col-lg-3 col-md-4 col-sm-4">10</div>
</div>

And the same code stopped working for me with Bootstrap 4:

.titulo {
  height: 200px;
  background: #666;
  border: 1px solid #333;
}

.dato {
  height: 100px;
  background: #666;
  border: 1px solid #333;
}

  <div class="dato col-lg-3 col-md-4 col-sm-4">8</div>
  <div class="dato col-lg-3 col-md-4 col-sm-4">9</div>
  <div class="dato col-lg-3 col-md-4 col-sm-4">10</div>
</div>

Question: How can I make the div .titulotake up 2 rows, and the divs .datowrap responsively, using the remaining space, according to whether it's a device smor lg? The divs have a fixed height (the title is 2 times the height of the rest).

It is worth clarifying that I build the small boxes dynamically with an ngForangular, therefore dividing them into containers in a fixed way is not an option. The code I have to generate them is:

<div class="dato col-lg-3 col-md-4 col-sm-6" 
*ngFor="let dato of datos">
    {{dato.nombre}}
</div>

What is the difference between an instance attribute/property and a class attribute/property? When do I use one and when do I use another in Python?

That is, if we have:

class Foo:
    a = 5

    def print_a(self):
        print(self.a)

Y:

class Foo:
    def __init__(self):
        self.a = 5

    def print_a(self):
        print(self.a)

What differences are there with respect to the attribute a?

I would like to know what is the problem with handling multiple inheritance in java? that is, I was working on something when I got to the point where I needed to inherit several abstract classes with extendsin Java but I realize that it is not allowed or at least I tried something like extends CLaseA,ClaseBI have searched for a while and I have not found anything that explains why that.

so can someone help me to know why? Also, since it is not possible to do this , what other alternatives do I have?

In jQuery there were at least four functions to manipulate DOM elements when the DOM was ready:

$( handler )
$( document ).ready( handler )
$( "document" ).ready( handler )
$( "img" ).ready( handler )
$().ready( handler )

Of these, perhaps the most used is the second:

$( document ).ready(function() {
  // Handler for .ready() called.
});

Which has been deprecated as of jQuery 3.

Although our code currently works, it may stop working in jQuery 4. Therefore, it is recommended to replace the previous code with this:

$(function() {
  // Handler for .ready() called.
});

The notice of obsolescence of document.readycan be found here :

As of jQuery 3.0, only the first syntax is recommended, ie $(function() { ... });The other syntaxes still work but are deprecated . This is because the selection has no bearing on the behavior of the method .ready (), which is inefficient and can lead to incorrect assumptions about the behavior of the method. For example, the third syntax works with "document" which doesn't select anything. The fourth syntax expects the document to be ready, but implies (incorrectly) that it expects the images to be ready.

The question

My question is regarding the older brother of $( document ).ready(function() {, that is, $(window).load(function() {});

Has jQuery 3 also changed from window.load?

If it has changed, what would be the way to update the code?
