Abgerundete Bilder

Verwenden Sie die Eigenschaft border-radius, um abgerundete Bilder zu erstellen:

Paris

Beispiel

Abgerundetes Bild:

       img {
  border-radius: 8px;
}
      

Probieren Sie es selbst aus →

<!DOCTYPE html>
<html>
<head>
<style>
img {
  border-radius: 8px;
}
</style>
</head>
<body>

<h2>Rounded Image</h2>

<p>Use the border-radius property to create rounded images:</p>

<img src="paris.jpg" alt="Paris" width="300" height="300">

</body>
</html>


Paris

Beispiel

Eingekreistes Bild:

       img {
  border-radius: 50%;
}
      

Probieren Sie es selbst aus →

<!DOCTYPE html>
<html>
<head>
<style>
img {
  border-radius: 50%;
}
</style>
</head>
<body>

<h2>Circled Image</h2>

<p>Use the border-radius property to create circled images:</p>

<img src="paris.jpg" alt="Paris" width="300" height="300">

</body>
</html>



Miniaturbilder

Verwenden Sie die Eigenschaft border, um Miniaturbilder zu erstellen.

Vorschaubild:

Paris

Beispiel

Probieren Sie es selbst aus →

<!DOCTYPE html>
<html>
<head>
<style>
img {
  border: 1px solid #ddd;
  border-radius: 4px;
  padding: 5px;
  width: 150px;
}
</style>
</head>
<body>

<h2>Thumbnail Image</h2>

<p>Use the border property to create thumbnail images:</p>

<img src="paris.jpg" alt="Paris" style="width:150px">

</body>
</html>


Miniaturbild als Link:

Beispiel

Probieren Sie es selbst aus →

<!DOCTYPE html>
<html>
<head>
<style>
img {
  border: 1px solid #ddd;
  border-radius: 4px;
  padding: 5px;
  width: 150px;
}

img:hover {
  box-shadow: 0 0 2px 1px rgba(0, 140, 186, 0.5);
}
</style>
</head>
<body>

<h2>Thumbnail Image as Link</h2>

<p>Use the border property to create thumbnail images. Wrap an anchor around the image to use it as a link.</p>
<p>Hover over the image and click on it to see the effect.</p>

<a target="_blank" href="paris.jpg">
  <img src="paris.jpg" alt="Paris" style="width:150px">
</a>

</body>
</html>



Responsive Bilder

Responsive Bilder passen sich automatisch an die Größe des Bildschirms an.

Ändern Sie die Größe des Browserfensters, um den Effekt zu sehen:

Cinque Terre

Wenn Sie möchten, dass ein Bild bei Bedarf verkleinert, aber niemals größer als seine Originalgröße skaliert wird, fügen Sie Folgendes hinzu:

Beispiel

img {
  max-width: 100%;
  height: 
auto;
}

Probieren Sie es selbst aus →

<!DOCTYPE html>
<html>
<head>
<style>
img {
  max-width: 100%;
  height: auto;
}
</style>
</head>
<body>

<h2>Responsive Image</h2>

<p>Responsive images will automatically adjust to fit the size of the screen.</p>
<p>Resize the browser window to see the effect:</p>

<img src="img_5terre_wide.jpg" alt="Cinque Terre" width="1000" height="300">

</body>
</html>


Tipp: Lesen Sie mehr über Responsive Webdesign in unserem CSS-RWD-Tutorial.


Zentrieren Sie ein Bild

Um ein Bild zu zentrieren, stellen Sie den linken und rechten Rand auf auto ein und machen Sie daraus ein Block-Element:

Paris

Beispiel

img {
  display: block;
    margin-left: auto;
  margin-right: auto;
   
width: 50%;
}

Probieren Sie es selbst aus →

<!DOCTYPE html>
<html>
<head>
<style>
img {
  display: block;
  margin-left: auto;
  margin-right: auto;
}
</style>
</head>
<body>

<h2>Center an Image</h2>

<p>To center an image, set left and right margin to auto, and make it into a block element.</p>

<img src="paris.jpg" alt="Paris" style="width:50%">

</body>
</html>



Polaroidbilder/Karten

Cinque Terre

Cinque Terre

Norway

Nordlichter

Beispiel

div.polaroid {
  width: 80%;
  background-color: white;
  box-shadow: 0 4px 8px 0 rgba(0, 
0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19);
}
img {width: 100%}

div.container {
  text-align: center;
  padding: 10px 20px;
}

Probieren Sie es selbst aus →

<!DOCTYPE html>
<html>
<head>
<style>
body {margin:25px;}

div.polaroid {
  width: 80%;
  background-color: white;
  box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19);
  margin-bottom: 25px;
}

div.container {
  text-align: center;
  padding: 10px 20px;
}
</style>
</head>
<body>

<h2>Responsive Polaroid Images / Cards</h2>

<div class="polaroid">
  <img src="img_5terre.jpg" alt="5 Terre" style="width:100%">
  <div class="container">
  <p>Cinque Terre</p>
  </div>
</div>

<div class="polaroid">
  <img src="lights600x400.jpg" alt="Norther Lights" style="width:100%">
  <div class="container">
  <p>Northern Lights</p>
  </div>
</div>

</body>
</html>



Transparentes Bild

Die Eigenschaft opacity kann einen Wert zwischen 0,0 und 1,0 annehmen. Je niedriger der Wert, desto transparenter:

Forest

Deckkraft 0,2

Forest

Deckkraft 0,5

Forest

Deckkraft 1
(Standard)

Beispiel

img {
  opacity: 0.5;
}

Probieren Sie es selbst aus →

<!DOCTYPE html>
<html>
<head>
<style>
img {
  opacity: 0.5;
}
</style>
</head>
<body>

<h1>Image Transparency</h1>

<p>The opacity property specifies the transparency of an element. The lower the value, the more transparent:</p>

<p>Image with 50% opacity:</p>
<img src="img_forest.jpg" alt="Forest" width="170" height="100">

</body>
</html>



Bildtext

So positionieren Sie Text in einem Bild:

Beispiel

Cingue Terre
Bottom Left
Top Left
Top Right
Bottom Right
Centered

Bildfilter

Die CSS-Eigenschaft filter fügt einem Element visuelle Effekte (wie Unschärfe und Sättigung) hinzu.

Hinweis: Die Filtereigenschaft wird in Internet Explorer oder Edge 12 nicht unterstützt.

Beispiel

Ändern Sie die Farbe aller Bilder in Schwarzweiß (100 % Grau):

 
   img {
  filter: grayscale(100%);
}

Probieren Sie es selbst aus →

<!DOCTYPE html>
<html>
<head>
<style>
body {
  background-color:white;
}
img {
  width: 33%;
  height: auto;
  float: left; 
  max-width: 235px;
}

.blur {filter: blur(4px);}
.brightness {filter: brightness(250%);}
.contrast {filter: contrast(180%);}
.grayscale {filter: grayscale(100%);}
.huerotate {filter: hue-rotate(180deg);}
.invert {filter: invert(100%);}
.opacity {filter: opacity(50%);}
.saturate {filter: saturate(7);}
.sepia {filter: sepia(100%);}
.shadow {filter: drop-shadow(8px 8px 10px green);}
</style>
</head>
<body>

<h2>Image Filters</h2>

<p><strong>Note:</strong> The filter property is not supported in Internet Explorer or Edge 12.</p>

<img src="pineapple.jpg" alt="Pineapple" width="300" height="300">
<img class="blur" src="pineapple.jpg" alt="Pineapple" width="300" height="300">

Responsive Bildergalerie

Mit CSS können Bildergalerien erstellt werden. In diesem Beispiel werden Medienabfragen verwendet, um die Bilder auf verschiedenen Bildschirmgrößen neu anzuordnen. Ändern Sie die Größe des Browserfensters, um den Effekt zu sehen:

Cinque Terre
Add a description of the image here
Forest
Add a description of the image here
Northern Lights
Add a description of the image here
Mountains
Add a description of the image here

Bildmodal (Erweitert)

Dies ist ein Beispiel, um zu zeigen, wie CSS und JavaScript zusammenarbeiten können.

Erstellen Sie zunächst mit CSS ein modales Fenster (Dialogfeld) und blenden Sie es aus Standard.

Verwenden Sie dann ein JavaScript, um das modale Fenster anzuzeigen und das Bild innerhalb des modalen Fensters anzuzeigen, wenn ein Benutzer auf das Bild klickt:

Northern Lights, Norway

Beispiel

// Get the modal
var modal = document.getElementById('myModal');
// Get the image and insert it 
inside the modal - use its "alt" text as a caption
var img = 
document.getElementById('myImg');

<h2>Image Modal</h2>

<p>Here, we use CSS to create a modal (dialog box) that is hidden by default.</p>
<p>We use JavaScript to trigger the modal and to display the current image inside the modal when it is clicked on. Also note that we use the value from the image's "alt" attribute as an image caption text inside the modal.</p>
<p>Don't worry if you do not understand the code right away. When you are done with CSS, go to our JavaScript Tutorial to learn more.</p>

<img id="myImg" src="img_lights.jpg" alt="Northern Lights, Norway" width="300" height="200">

<!-- The Modal -->
<div id="myModal" class="modal">
  <span class="close">&amp;times;</span>
  <img class="modal-content" id="img01">
  <div id="caption"></div>
</div>

<script>
// Get the modal
var modal = document.getElementById('myModal');

// Get the image and insert it inside the modal - use its "alt" text as a caption
var img = document.getElementById('myImg');
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
img.onclick = function(){
  modal.style.display = "block";
  modalImg.src = this.src;
  captionText.innerHTML = this.alt;
}

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];

// When the user clicks on <span> (x), close the modal
span.onclick = function() { 
  modal.style.display = "none";
}
