I'm trying to set up a scrolling gallery, but not sure how to proceed.
The following is what I'm looking for (see attached as well):
15-20 images with different sizes
Define spacing between the images (pink areas)
The container to be the specific height on certain breakpoints (desktop, tablet, mobile), and then which the images will adapt to in order to keep their ratios and layout according to my attached example.
Scroll from right to left and start over once the last image is being shown, so it starts over smooth.
I'm thinking the following, but don't know how to make the images adopt the right way depending on screen size?
.container{
display: flex;
position: relative;
max-height: 700px;
height: 100%;
width: 100%;
overflow-x: hidden;
}
.image{
display: block;
position: absolute;
}
This page centers and shrinks my logo to fit in the browser window. It uses a single PNG file and CSS flexbox with max-width/max-height. (View code)
This page animates the same logo. However, in order to limit the ripple effect to just the blue portion, some changes were needed (view code):
Logo split into two parts and stacked on top of each other (position:absolute).
Hard-coded the size of the logo. (No longer sized based on size of browser window)
I can't figure out two things:
How do I change the hard-coded sizes back to dynamic sizes based on the browser size? I also hard-coded the top and left, but if the two images are centered and scaled by the same ratio, they should line up properly without offsets.
How do I vertically/horizontally center the logo, again? I think my previous flexbox CSS doesn't work because the elements have position:absolute. Update: I was able to get centering to work again, but this involved more hard-coded width/heights.
I think I can do this via JavaScript, but is a pure CSS/HTML solution possible? (I have a feeling centering and dynamically sizing elements with position:absolute might not be possible). If JavaScript is disabled, the solution should gracefully degrade (the two parts of the logo are correctly aligned; the logo fits inside browser window).
Example: https://jsfiddle.net/2rdjfwhb/1/
It is possible to do both with CSS, you just need another wrapper element around the "logo" class. This wrapper element can be positioned naturally inside of a flexbox. After that it's just about calculating the ratio you need for your logo image and the ripple canvas.
.parent {
max-height: 100%;
max-width: 100%;
}
.logo {
width: 100%;
height: 100%;
position: relative; /* Parent handles centering this guy now */
}
.logo-ligature {
width: 100%;
height: 100%;
position: relative; /* Positioned for z-index */
pointer-events: none;
}
.logo-background {
background-image: url(https://cdn.glitch.com/b2cea96d-c2a3-486e-90d5-f60a651a36e3%2Fle_square_light_noborder.png?1553791477453);
background-size: contain;
background-position: center; /* Center the image */
background-repeat: no-repeat; /* Do not repeat the image */
width: 75%;
height: 75%;
position: absolute;
top: 12.5%;
left: 12.5%;
}
I've got a cordova app using jquery, jquery-mobile, iscroll and iscrollview
I'm not exactly committed to any of these tools.
I've got the jquery-mobile header/footer stuck to the top and bottom of the screen just fine.
I have a scrollable div between the header and footer. It will contain variable amounts of data. Sometimes the data will be less than the height of the div and sometimes it will be greater (hence the scrolling)
Here's the tricky part. I want to stick the bottom of the scrollable div to the top of the footer. When I add stuff to the div i want the most recently added closest to the top of the footer so the top of the scrollable div looks like its growing upwards towards the bottom of the header as data is added.
Once the top of the scrollable div is fille by its content then i want to be able to scroll it.
Has anyone been able to achieve something like this?
Here's a neat little trick for you.
<div class="header"></div>
<div class="content"></div>
<div class="footer"></div>
Now the CSS
div {
width: 100%;
}
.header {
position: absolute;
top: 0px;
left: 0px;
height: 50px;
}
.footer {
position: absolute;
bottom: 0px;
left: 0px;
height: 100px;
}
/* the magic */
.content {
position: absolute;
top: 50px; /* matches height of header */
bottom: 100px; /* matches height of footer */
left: 0px;
overflow: scroll;
}
The neat thing about forcing .content to have both a top and a bottom is that it stretches the div so that it's always the proper height. IF you specified height on it, it wouldn't work, but because the height is determined by the top/bottom property, it's dynamic. I think this gets you to where you want to be.
Here's a fiddle
Edit: Here's what it looks like with content
Edit 2 - forcing content to grow from the bottom.
I'm not sure this is a good idea, and I'm not sure I would ever seriously recommend doing things this way. However, using vertical-align it's possible to force content to grow from the bottom. I suspect that it would be better to just set a margin with javascript that shrunk as content grew, but... maybe not. With all that said, here's one way to do things with CSS.
This requires a little bit of restructuring of the content div.
<div class="content">
<span class="margin"></span>
<span class="inner"></span>
</div>
And a little bit more CSS
span.left-margin {
height: 98%;
width: 0px;
display: inline-block;
}
span.inner {
width: 99%;
background-color: white;
display: inline-block;
vertical-align: bottom;
}
It looks like this with a little content
It looks like this with a lot of content
If you want the scroll bar to stick to the bottom as content comes in, you'll need to do some javascript (easy to google it).
I'm not completely happy with doing things this way because if you set height 100% or width 100%, the content div gets a scrollbar automatically from the beginning. However... it looks pretty good and should work in most (if not all) browsers.
See my problem here:

I want to have divs scroll on and off the screen using jquery, but I do not want any horizontal scrollbars. The only way I know how to do that is to make a container and do overflow:hidden. Here is my container CSS
#container {
top:0px;
position: absolute;
margin: 0px;
padding: 0px;
width: 100%;
height: 100%;
overflow: hidden;
}
I had to make the width and height 100% so that no matter what I scrolled across it would not be cut off.
When I make this container then everything behind it becomes unclickable and pretty much disabled. I want the page behind the scrolling divs to still behave normally where I can click and interact with it. How can I achieve that?
I'm having some issues with a webpage of mine, mainly on mobile devices but it also affects desktop devices too, I would be willing to award a bounty (as and when stackoverflow allows me) to whomever can help with these problems

Issue 1 - Left/Right Scroll Image Buttons
Currently my left and right scroll image buttons are done in html using onmouseover and onmouseout I want to be able to convert them into css based "buttons"
Issue 2 - Dynamic Resolution(s)
The header and footers aren't dynamic with different resolutions for example, I created the page designed on a 1680x1050 monitor which looks like: Desktop 1680x1050 however making the window smaller it looks like: Desktop Small Window
On a Nexus 4 mobile phone on default zoom it looks like: Mobile Original Zoom
On a Nexus 4 mobile phone zoomed out to as far as it can go it looks like: Mobile Max Distance
On a Nexus 4 zoomed out and scrolled to the bottom (so that the browsers URL bar disappears) it looks like: Zoomed out without URL bar (the footer of the actual webpage vanishes)
On a Nexus 4 zoomed out and scrolled just off from the bottom (so that the browsers URL bar is visible) it looks like: Zoomed out with URL bar (the footer returns)
.
The placeholder image and arrows are supposed to be in the center of the footer and headers and should shrink in accordance to the screen resolution.
Mobile device default zoom (if possible) needs to be decreased so they can see more and on getting smaller (if possible) if it gets close to Mobile Original Zoom then the Up to Top, Down to Key, placeholder logos should vanish...
Please see images at bottom of this post
For the mobile devices I tried things like below just for testing but none of them worked...
#media (max-width: 640px) {
#header > a img {
display: none;
}
}
EDIT 14/11/2013 # 01:58GMT
On a 1920x1080 screen it looks kind of okay although there is a big gap between the text and the placeholder image as seen below:
On a 1680x1050 screen it looks roughly how it should take note of where "Semi" is located and compare to the 1920x1080 image from above.
On a 600x600 screen it appears as follows, which as you can see there is a big gap between the placeholder and the left arrow but on the right arrow there is no gap and infact it overflows, as for the text it too is too far to the right.
Type
#media screen and (max-width:640px) {
/* Your specific styles go here */
}
and dont forget to add
<meta name="viewport" content="width=device-width,initial-scale=1.0">
Hope that helps :-)
I see a border around your links, remove from your links:
a{
border:none ;
}
for first issue you can do it with CSS, just remove <img> tag inside <a> tag like this:
<div class="footleft">
<a class="def" href="javascript: void(0);">
</a>
</div>
create image buttons like this:
then set background to <a> tag like this:
#footer .footleft a {
width: 100px;
height: 47px;
display: block;
background: url(path/to/leftarrow.png);
background-position: 0 0;
}
#footer .footright a{
width: 100px;
height: 47px;
display: block;
background: url(path/to/rightarrow.png);
background-position: 0 0;
}
#footer .footleft a:hover , #footer .footright a:hover{
background-position: 0 100%;
}
second issue, I think if you remove position:absolute; from #header .headimage and #footer .footimage it will be okay.
and if your want to centerize headmid and footmid and footmidtwo you have two choices,
First: set fixed width to them and use CSS like this:
#footer .footmid {
top: 50%;
left: 50%;
position: absolute;
font-size: 15px;
width: 292px;
margin-left: -146px;
}
#footer .footmidtwo {
top: 70%;
left: 50%;
position: absolute;
font-size: 15px;
width: 126px;
margin-left: -63px;
}
#header .headmid {
top: 60%;
left: 50%;
position: absolute;
font-size: 15px;
width: 302px;
margin-left: -151px;
}
Second: if you need to have dynamic width you can use this CSS and JQuery:
CSS:
#header .headmid {
top: 60%;
left: 50%;
position: absolute;
font-size: 15px;
}
#footer .footmid {
top: 50%;
left: 50%;
position: absolute;
font-size: 15px;
}
#footer .footmidtwo {
top: 70%;
left: 50%;
position: absolute;
font-size: 15px;
}
JQuery:
var $widthhead = $(".headmid").width();
var $widthfoot = $(".footmid").width();
var $widthfoot2 = $(".footmidtwo").width();
$(".headmid").css("margin-left",$widthhead/2*(-1));
$(".footmid").css("margin-left",$widthfoot/2*(-1));
$(".footmidtwo").css("margin-left",$widthfoot2/2*(-1));

Okay I've tried to filter out all of the irrelevant code for this solution.
See the solution here.
Most of the time, it is best to use relative positioning to fit elements absolutely inside of another element. In your case, with three different strings to fit in a 300x80 window, it's a bit crowded. I tried to place things in a logical position to demonstrate.
By placing a container in the footimage div with relative position, you can then place every element inside the footimage div absolutely relavtive to the footimage div, rather than to the entire page.
For example, what you had:
#footer .footmid
{
position: absolute;
top: 50%;
left: 50%;
}
Will place the div of class footmid at a position 50% of the page height from the top of the page and 50% of the page width from the left of the page:
This will work if every user that visits your page has the exact same resolution, however it causes problems when the don't. Obviously, this isn't a perfect world, so different resolutions will visit your page.
What you can do is use relative positioning!
Basically I tell CSS that instead of moving 50% from the top and left of the window, move 50% from the top and left of the nearest parent element with relative positioning:
You can modify the bottom, left, and right attributes of my fiddle to move the footmid elements within the relative element .footimageContainer that is the same size and in the same position as the .footimage.
As far as your arrows, I wasn't quite sure what you were trying to accomplish; your question was pretty vague, so I simply made them fade out slightly when you mouseover them. Any mouseover/out events can be handled using CSS psuedo-elements.
.element //Native and mouseout
{}
.element:hover //onmouseover
{}
Remember that if you use pseudo-elements, you have to specify the attribute that will be changing in both the native and :hover rules.
.element
{color:red;}
.element
{color:black;}
If you have any additional questions on the arrows, let me know and I'll revise my answer.
http://jsfiddle.net/D8SJD/4/
Instead of using absolute positioning, you can just take advantage of the text-align center and images and text will center automatically.
If you want offset from center, try position:relative, and top, left, right etc and it will move relative to it's central position.
Elements that are display:inline; or display:inline-block; will align according to parents text-align property, in this case text-align:center.
#footer .footimage {
display:inline;
position:relative;
top:-10px;
}
#footer .footmid {
top: 50%;
width:100%;
position: absolute;
font-size: 15px;
}
#footer .footmidtwo {
top: 70%;
width:100%;
position: absolute;
font-size: 15px;
}
As per issue 2, i could be wrong but when targeting the image through the structure of the site
i.e.
headImg a img{...}
The style wouldn't work. But if you add classes to the images the style will work; the case could be that there are some unclosed divs or elements messing with the architecture.
<div class="headimage">
<img class="placeholder" src="http://placehold.it/300x80"/>
</div>
#media screen and (max-width: 640px) {
.placeholder {
display: none;
}
}
