Bonjour,

Je fais appel à vous aujourd'hui parce que j'essaie de centrer verticalement une div sur ma page.

J'avais très bien réussi au début avec le code suivant :

<div class="row h-100">
  <div class="col-md-3 my-auto">
    <img src="public/img/1.jpg" class="img-circle img-no-padding img-responsive" alt="Rounded Image" width=200 height=200>
  </div>
  <div class="col-md-9 my-auto">
    <h1 class="merriweather text-white mb-3">Titre</h1>
    <p class="merriweather text-white">Again and again, we've seen him make tough choices when easier ones were available. I was not raised in a particularly religious household. And if we can do that - if we can embrace a common destiny - then I believe we'll not just help bring about a more hopeful day in America, we'll not just be caring for our own souls, we'll be doing God's work here on Earth. But the truth is, that isn't all that I know of the man. The profound mistake of Reverend Wright's sermons is not that he spoke about racism in our society. But we have a responsibility to join together on behalf of the world we seek - a world where extremists no longer threaten our people, and American troops have come home; a world where Israelis and Palestinians are each secure in a state of their own, and nuclear energy is used for peaceful purposes; a world where governments serve their citizens, and the rights of all God's children are respected.</p>
    </div>
  </div>
</div>

Sauf que les choses ont fait que je suis maintenant obligée d'entourer ce bout de code par un <div class="container">, ce qui me donne :

<div class="container">
  <div class="row h-100">
    <div class="col-md-3 my-auto">
      <img src="public/img/1.jpg" class="img-circle img-no-padding img-responsive" alt="Rounded Image" width=200 height=200>
    </div>
    <div class="col-md-9 my-auto">
      <h1 class="merriweather text-white mb-3">Titre</h1>
      <p class="merriweather text-white">Again and again, we've seen him make tough choices when easier ones were available. I was not raised in a particularly religious household. And if we can do that - if we can embrace a common destiny - then I believe we'll not just help bring about a more hopeful day in America, we'll not just be caring for our own souls, we'll be doing God's work here on Earth. But the truth is, that isn't all that I know of the man. The profound mistake of Reverend Wright's sermons is not that he spoke about racism in our society.

Et ici le code ne marche plus du tout, et je ne comprends pas pourquoi. J'ai essayé d'autres choses, comme align-self-center, mais rien n'y fait.

Sauriez-vous pourquoi mon code ne marche plus ? :/

Merci
