J'ai trouvé cette solution CodePen pour un pied de page collant dans une mise en page CSS Grid, mais cela me pose deux problèmes:
min-height: 100%
et height: 100%
J'ai besoin de quelque chose qui fonctionne avec cette structure HTML:
<body>
<nav>Some navigation buttons</nav>
<main>The content</main>
<footer>Copyrights and stuff</footer>
</body>
Je ne veux pas vraiment emballer le <nav>
et le <main>
dans un <div>
, et j'aimerais le faire en CSS pur.
// Not required!
// This is just to demo functionality.
$("#add").on("click", function() {
$("<p>Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Vestibulum tortor quam, feugiat vitae, ultricies eget, tempor sit amet, ante. Donec eu libero sit amet quam egestas semper. Aenean ultricies mi vitae est. Mauris placerat eleifend leo.</p>").appendTo(".content");
});
html {
height: 100%;
}
body {
min-height: 100%;
display: grid;
grid-template-rows: 1fr auto;
}
.content {
padding: 20px;
}
.footer {
grid-row-start: 2;
grid-row-end: 3;
}
* {
box-sizing: border-box;
}
body {
margin: 0;
font: 16px Sans-Serif;
}
h1 {
margin: 0 0 20px 0;
}
p {
margin: 0 0 20px 0;
}
.footer {
background: #42A5F5;
color: white;
padding: 20px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="content">
<h1>Sticky Footer with Grid</h1>
<p><button id="add">Add Content</button></p>
</div>
<footer class="footer">
Footer
</footer>
Voici une solution CSS Grid, mais il est de loin préférable d'utiliser une classe pour la cible.
En utilisant des zones de grille, ce sera très simple:
html,body{
height: 100%;
}
body{
margin: 0;
}
body {
display: grid;
grid-gap: 10px;
height: 100%;
grid-template-columns:1fr;
grid-template-areas:
"nav"
"main"
"footer";
grid-template-rows: 100px 1fr 80px;
}
nav {
grid-area: nav;
}
main {
grid-area: main;
}
footer {
grid-area: footer;
}
nav {
background-color: #7E57C2;
}
main {
background-color: #F8BBD0;
}
footer {
background-color: #7E57C2;
}
CSS Grid est un excellent outil pour assembler des mises en page complexes.
Mais vous recherchez une grille simple à une colonne, avec trois lignes et le pied de page épinglé au bas du conteneur.
Je suggérerais que flexbox est une solution plus simple et plus efficace dans ce cas. (Vous pouvez toujours utiliser la grille dans chaque élément flexible.)

$("#add").on("click", function() {
$("<p>Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Vestibulum tortor quam, feugiat vitae, ultricies eget, tempor sit amet, ante. Donec eu libero sit amet quam egestas semper. Aenean ultricies mi vitae est. Mauris placerat eleifend leo.</p>").appendTo("p");
});
body {
display: flex;
flex-direction: column;
min-height: 100vh;
margin: 0;
}
nav {
flex: 0 0 100px;
background-color: lightgreen;
}
main {
background-color: orangered;
}
footer {
flex: 0 0 100px;
margin-top: auto; /* pin footer to the bottom; see link below for details */
background-color: lightgray;
}
nav, main, footer {
display: flex;
align-items: center;
justify-content: center;
text-align: center;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<nav>Nav</nav>
<main>
<p><button id="add">Add Content</button></p>
</main>
<footer>Footer</footer>

Le pied collant est obtenu avec une seule ligne de code CSS, à savoir: min-height: 100vh
.
Exemple ci-dessous:
body {
width: 100%;
height: 100%;
margin: 0;
display: grid;
grid-template-columns: [column-line-1] minmax(128px, 256px) [column-line-2] auto [column-line-3] minmax(128px, 256px) [column-line-4];
grid-template-rows: [row-line-1] 48px [row-line-2] auto [row-line-3] auto [row-line-4] auto [row-line-5] auto [row-line-6];
background:#fafafa;
/*Below provides sticky footer*/
min-height: 100vh;

L'astuce consiste à utiliser:
min-height: 100vh; grid-template-rows: auto auto 1fr;
avec ...
align-self: end;
pour le pied de page.
Si nous ajoutons des marges gauche/droite, placez le <nav>
dans un en-tête, ajoutez une marge pour le contenu du pied de page et utilisez une autre grille pour le contenu principal:
body {
display: grid;
grid-gap: 1em 0;
grid: auto auto 1fr / 10vw 1fr 10vw;
margin: 0;
min-height: 100vh;
}
header {
grid-column: 2;
}
main {
display: grid;
grid-column: 2;
}
footer {
align-self: end;
grid-column: 2;
margin-bottom: 1em;
}
Cela présente une élégante simplicité qui manque aux solutions précédentes.
Avec les navigateurs à feuilles persistantes il n’est pas nécessaire de compliquer les choses.
Les réponses précédentes ne sont pas aussi faciles à gérer. Les pièges comprennent:
