Website layout

Et websted er ofte opdelt i overskrifter, menuer, indhold og en sidefod:

Header
Navigation Menu
Content
Main Content
Content
Footer

Der er tonsvis af forskellige layoutdesigns at vælge imellem. Strukturen ovenfor er dog en af de mest almindelige, og vi vil se nærmere på den i denne tutorial.

Header

En header er normalt placeret øverst på hjemmesiden (eller lige under en topnavigationsmenu). Det indeholder ofte et logo eller webstedets navn:

Eksempel

   .header {
  background-color: #F1F1F1;
  text-align: 
   center;
  padding: 20px;
}

/* Style the header */
.header {

  padding: 20px;
  text-align: center;
}
</style>
</head>
<body>

<div class="header">
  <h1>Header</h1>
</div>

</body>
</html>

Navigations bar

En navigationslinje indeholder en liste over links, der hjælper besøgende med at navigere gennem dit websted:

Eksempel

   /* The navbar container */
.topnav {
  overflow: hidden;
  
   background-color: #333;
}
/* Navbar links */
.topnav a {
  float: 
   left;
  display: block;
  color: 
   #f2f2f2;
  text-align: center;
  
   padding: 14px 16px;
  text-decoration: none;
}

   /* Links - change color on hover */
.topnav a:hover {
  
   background-color: #ddd;
  color: black;
}

Indhold

Layoutet i dette afsnit afhænger ofte af målbrugerne. Det mest almindelige layout er en (eller ved at kombinere dem) af følgende:

  • 1-kolonne (bruges ofte til mobilbrowsere)

  • 2-kolonne (bruges ofte til tablets og bærbare computere)

  • 3-kolonne layout (bruges kun til desktops)

1-column:

 

2-column:

 

3-column:

Vi vil skabe et 3-søjlelayout og ændre det til et 1-søjlelayout på mindre skærme:

Eksempel

   /* Create three equal columns that float next to each other */
.column {
  
   float: left;
  width: 33.33%;
}
/* Clear floats after the 
   columns */
.row:after {
  content: "";
  
   display: table;
  clear: both;
}
/* Responsive 
   layout - makes the three columns stack on top of each other instead of next 
   to each other on smaller screens (600px wide or less) */
@media screen and (max-width: 
   600px) {
  .column 
   {
    width: 100%;
  }
}

Resultat

Tip: For at oprette et 2-søjlelayout skal du ændre bredden til 50 %. For at oprette et 4-kolonne layout skal du bruge 25 % osv.

Tip: Undrer du dig over, hvordan @media-reglen fungerer? Læs mere om det i vores CSS Media Queries kapitel.

Tip: En mere moderne måde at skabe kolonnelayout på er at bruge CSS Flexbox. Det understøttes dog ikke i Internet Explorer 10 og tidligere versioner. Hvis du har brug for IE6-10-understøttelse, skal du bruge flydere (som vist ovenfor).

Ulige kolonner

Hovedindholdet er den største og vigtigste del af dit websted.

Det er almindeligt med ulige søjlebredder, så det meste af pladsen er reserveret til hovedindholdet. Sideindholdet (hvis nogen) bruges ofte som et alternativ navigation eller for at angive oplysninger, der er relevante for hovedindholdet. Skift bredderne, som du vil, husk kun, at det skal være op til 100 % i alt:

Eksempel

   .column {
  float: left;
}
/* Left and right column */
   .column.side {
  width: 25%;
}
/* Middle column */
.column.middle 
   {
  width: 50%;
}
/* Responsive layout - makes 
   the three columns stack on top of each other instead of next to each other */
   @media screen and (max-width: 600px) {
  .column.side, .column.middle 
   {
    width: 100%;
  }
}

Sidefod

Sidefoden er placeret nederst på din side. Det indeholder ofte oplysninger som copyright og kontaktoplysninger:

Eksempel

   .footer {
  background-color: #F1F1F1;
  text-align: 
   center;
  padding: 10px;
}

Responsive hjemmesidelayout

Ved at bruge noget af CSS-koden ovenfor, har vi skabt et responsivt webstedslayout, som varierer mellem to kolonner og kolonner i fuld bredde afhængigt af skærmbredden:
