Idea came by surfing web and saw on some site how they made this awesome effect. There is similar effect on my blog, maybe better, but this one isn't bad at all on contrary, you will see and you will lke it 100%. Take a look at the site I mentioned above, you may find some solution how to implement this hack. You have to know CSS, HTML i jQuery for this. Here is one way - Zoom Effect 1 ,read it, it's cool. The only diference is in codes and style. This one is a little harder for beginners.
HTML <img class="magniflier" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj8vgSzzMMt-SmXt20uu4jzn18vlAnu9VMJwHhPi9ciAGMiPUNFa3WOhuVmmcNSVXFFue7HhpJVsbyu44iUCehGxl2-qqltuomJY2qZz361GSAEFAgKASBxgO7YqzsB4A_Cdaff4HVeOU4/s1600/iphone-5-thumb%5B1%5D.jpg" width="460"/>
Replace "image.jpg" with your image URL
.glass {
width: 170px;
height: 170px;
position: absolute;
border-radius: 50%;
cursor: crosshair;
/* Multiple box shadows to achieve the glass effect */
box-shadow:
0 0 0 7px rgba(255, 255, 255, 0.85),
0 0 7px 7px rgba(0, 0, 0, 0.25),
inset 0 0 40px 2px rgba(0, 0, 0, 0.25);
display: none;
}
CSS gives you style and make Magnify
jQuery
$(function() {
var native_width = 0;
var native_height = 0;
var mouse = {x: 0, y: 0};
var magnify;
var cur_img;
var ui = {
magniflier: $('.magniflier')
};
// Connecting to the magnifying glass
if (ui.magniflier.length) {
var div = document.createElement('div');
div.setAttribute('class', 'glass');
ui.glass = $(div);
$('body').append(div);
}
// All the magnifying will happen on "mousemove"
var mouseMove = function(e) {
var $el = $(this);
// Container offset relative to document
var magnify_offset = cur_img.offset();
// Mouse position relative to container
// pageX/pageY - container's offsetLeft/offetTop
mouse.x = e.pageX - magnify_offset.left;
mouse.y = e.pageY - magnify_offset.top;
// The Magnifying glass should only show up when the mouse is inside
// It is important to note that attaching mouseout and then hiding
// the glass wont work cuz mouse will never be out due to the glass
// being inside the parent and having a higher z-index (positioned above)
if (
mouse.x < cur_img.width() &&
mouse.y < cur_img.height() &&
mouse.x > 0 &&
mouse.y > 0
) {
magnify(e);
}
else {
ui.glass.fadeOut(100);
}
return;
};
var magnify = function(e) {
// The background position of div.glass will be
// changed according to the position
// of the mouse over the img.magniflier
//
// So we will get the ratio of the pixel
// under the mouse with respect
// to the image and use that to position the
// large image inside the magnifying glass
var rx = Math.round(mouse.x/cur_img.width()*native_width - ui.glass.width()/2)*-1;
var ry = Math.round(mouse.y/cur_img.height()*native_height - ui.glass.height()/2)*-1;
var bg_pos = rx + "px " + ry + "px";
// Calculate pos for magnifying glass
//
// Easy Logic: Deduct half of width/height
// from mouse pos.
// var glass_left = mouse.x - ui.glass.width() / 2;
// var glass_top = mouse.y - ui.glass.height() / 2;
var glass_left = e.pageX - ui.glass.width() / 2;
var glass_top = e.pageY - ui.glass.height() / 2;
//console.log(glass_left, glass_top, bg_pos)
// Now, if you hover on the image, you should
// see the magnifying glass in action
ui.glass.css({
left: glass_left,
top: glass_top,
backgroundPosition: bg_pos
});
return;
};
$('.magniflier').on('mousemove', function() {
ui.glass.fadeIn(100);
cur_img = $(this);
var large_img_loaded = cur_img.data('large-img-loaded');
var src = cur_img.data('large') || cur_img.attr('src');
// Set large-img-loaded to true
// cur_img.data('large-img-loaded', true)
if (src) {
ui.glass.css({
'background-image': 'url(' + src + ')',
'background-repeat': 'no-repeat'
});
}
// When the user hovers on the image, the script will first calculate
// the native dimensions if they don't exist. Only after the native dimensions
// are available, the script will show the zoomed version.
//if(!native_width && !native_height) {
if (!cur_img.data('native_width')) {
// This will create a new image object with the same image as that in .small
// We cannot directly get the dimensions from .small because of the
// width specified to 200px in the html. To get the actual dimensions we have
// created this image object.
var image_object = new Image();
image_object.onload = function() {
// This code is wrapped in the .load function which is important.
// width and height of the object would return 0 if accessed before
// the image gets loaded.
native_width = image_object.width;
native_height = image_object.height;
cur_img.data('native_width', native_width);
cur_img.data('native_height', native_height);
//console.log(native_width, native_height);
mouseMove.apply(this, arguments);
ui.glass.on('mousemove', mouseMove);
};
image_object.src = src;
return;
} else {
native_width = cur_img.data('native_width');
native_height = cur_img.data('native_height');
}
//}
//console.log(native_width, native_height);
mouseMove.apply(this, arguments);
ui.glass.on('mousemove', mouseMove);
});
ui.glass.on('mouseout', function() {
ui.glass.off('mousemove', mouseMove);
});
});
Final Words. If you want to get back your pictures to normal, without magnifying, simply switch <img class="magniflier" to normal code which was before you added this one.
That's it, if you can handle, please, lieve a comment, that would be so valuable, if not, we will try to find some solution, jQuery and CSS are hard to manage but nothing is impossible. Happy Blogging dear friends !
