CSS -stileerbeelde
Leer hoe om beelde te styl met CSS.
Afgeronde beelde
Gebruik die border-radiuseiendom om afgeronde beelde te skep:
Voorbeeld
Afgeronde beeld:
img {
border-radius: 8px;
}
Voorbeeld
Omringde prent:
img {
border-radius: 50%;
}
Kleinkiekie prente
Gebruik die bordereiendom om duimnaelbeelde te skep.
Kleinkiekieprent:
Voorbeeld
img {
border: 1px solid #ddd;
border-radius: 4px;
padding: 5px;
width: 150px;
}
<img src="paris.jpg"
alt="Paris">
Kleinkiekieprent as skakel:
Voorbeeld
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);
}
<a href="paris.jpg">
<img src="paris.jpg" alt="Paris">
</a>
Responsiewe beelde
Responsiewe beelde sal outomaties aanpas om by die grootte van die skerm te pas.
Verander die grootte van die blaaiervenster om die effek te sien:
As jy wil hê dat 'n prent afskaal as dit moet, maar nooit opskaal om groter as sy oorspronklike grootte te wees nie, voeg die volgende by:
Voorbeeld
img {
max-width: 100%;
height:
auto;
}

Sentreer 'n prent
Om 'n prent te sentreer, stel die linker- en regterkantlyn op autoen maak dit 'n blockelement:
Voorbeeld
img {
display: block;
margin-left: auto;
margin-right: auto;
width: 50%;
}
Polaroid beelde / kaarte
Vyf lande
Noordeligte
Voorbeeld
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;
}
Deursigtige beeld
Die opacityeiendom kan 'n waarde van 0.0 - 1.0 neem. Hoe laer waarde, hoe meer deursigtig:
ondeursigtigheid 0.2
opacity 0.5
opacity 1
(default)
Example
img {
opacity: 0.5;
}

Image Filters
The CSS filter property adds visual effects (like blur and saturation) to an element.
Note: The filter property is not supported in Internet Explorer or Edge 12.
Example
Change the color of all images to black and white (100% gray):
img {
filter: grayscale(100%);
}

Example
Fade in a box:
Example
Slide in (top):
Example
Slide in (bottom):
Example
Slide in (left):
Example
Slide in (right):
Flip an Image
Move your mouse over the image:
Example
img:hover {
transform: scaleX(-1);
}
Responsive Image Gallery
CSS can be used to create image galleries. This example use media queries to re-arrange the images on different screen sizes. Resize the browser window to see the effect:
Example
.responsive {
padding: 0 6px;
float: left;
width: 24.99999%;
}
@media only screen and
(max-width: 700px){
.responsive {
width: 49.99999%;
margin: 6px
0;
}
}
@media only screen and (max-width: 500px){
.responsive {
width: 100%;
}
}

Image Modal (Advanced)
This is an example to demonstrate how CSS and JavaScript can work together.
First, use CSS to create a modal window (dialog box), and hide it by default.
Then, use a JavaScript to show the modal window and to display the image inside the modal, when a user clicks on the image:
Example
// 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";
}
