Stuff you can do with <code>pointer-events</code>
</h1>
<p>
<code>pointer-events</code> is mostly used to bypass click events on an element. But did you know you can reset the pointer events of descendant elements? This allows us to do some interesting things…

1. Change styling of a parent on hover
</h2>
<p>
The hover styling of the card is not set unless the button is hovered. Keep in mind this technique disables the ability to open the image-specific context menu when the image is right-clicked (Thanks Šime Vidas for <a href="<a href="https://twitter.com/simevidas/status/1020867060614811649"">https://twitter.com/simevidas/status/1020867060614811649"</a>; target="_blank">pointing that out</a>).

Je te recommande plutôt les articles de Tom Butler : https://r.je/
Euh, il suffit de faire un lien symbolique vers le dossier en question...
Par exemple, pour un dossier www/html situé dans "Mes Documents", ouvrir un terminal et taper les commandes suivantes :
mkdir "~/Mes Documents/www"
mkdir "~/Mes Documents/www/html"
sudo chmod 777 "~/Mes Documents/www"
sudo mv /var/www /var/www_old
sudo ln -s "~/Mes Documents/www" /var/wwwPas besoin de Node.js pour ça...
Merci.
Je vais vérifier ça une fois au boulot.
J'essaie de me rendre sur le site de Tor et la connexion est dite non sécurisée (avec Firefox et IE sous windows).
Vous savez si c'est normal ?
Joli reprise. J'aime bien la guitare.
Parce que c'est null ! :-)
Une autre approche de la gestion du développement logiciel.
Pas de salariat. Payé à l'acte.
Serait-ce là le début d'un nouveau statut que l'on pourrait appeler "intermittent de la programmation" ?
Encore un article qui démontre que tout ce que j'ai appris, ben, c'est de la merde.
Plutôt que de penser ses classes en terme d'héritage (est-un), il vaut mieux penser en terme de composition (possède-un ou est-composé-de).
L'héritage est une mauvaise pratique, le plus souvent, car cela rompt l'encapsulation et souvent engendre une répétition inutile de code (coucou Symphony, coucou Cake...).
La composition permet de l'éviter.
Le seul moment où il est nécessaire d'utiliser l'héritage est lorsque l'on n'a pas écrit la classe de base et que l'on doive modifier un de ses comportements sans pouvoir utiliser un patron d'adaptation.
Pourquoi l'encapsulation est nécessaire aux objets et qu'il faut faire en sorte de ne pas la rompre.
J'ai pris un screenshot histoire de ne pas perdre ces astuces :
Vu sur Twitter durant l'été. Ça m'a fait marrer...
