css: shrinking images leave wide white margins on right - javascript

Update: the problem is in javascript. See comment at below
My website (Link) has 6 sliding images beneath the menu. I want to shrink the sizes of these images from 600 x 300 to 400 x 200. However, shrinking will leave wide white margins on the right side (see the developing version). In the css file, I looked at all the ul#images codes (see below) and could not figure out how to remove the white margins. Thanks for your input:
/* Image Transitions */
ul#images {
margin: 0 15px 10px 0;
padding: 0;
list-style: none;
position: relative;
}
ul#images li {
display: block;
overflow: hidden;
padding: 0;
float: left;
width: 155px; <!-- ?the portion shown initially-->
height: 300px; <!-- -->
}

The problem is not in your css, it is in the javascript, it is setting the other pictures to 66px wide on mouse over, make this width larger to fill in the white space.
Post your javascript and I will gladly fix it for you.

CSS overflow: auto by 'touching' bottom div

I want to make a div scrollable when its touching the bottom div.
I tried this:
margin-bottom:30px;
position: relative;
overflow: auto;
but it didn't work.
I created a fiddle tho show you my problem:
https://jsfiddle.net/wp3wvuj2/1/
For explanation: When you type in in a input field a new field is added to the div (This function is simplified). I want that before the input fields touch the element below (the START-div) it gets scrollable (overflow: auto).
Somebody have an idea?
Edit:
I noticed that nobody understands my problem.
I'll try to explain it better:
I have list where players add their names. The list has minimum 4 players maximum ∞.
The start buttonis placed at the bottom. The problem is in a iphone 5 it looks like this:
And now if i would add another player input field it would Overlap with the START-Button. Thats the reason why I want it scrollable now. I already get that work with a fixed height, but i want it responsive!
Because on a iPad for example it looks like this:
And I want prevent an overlap with the start button like this:
So it should get scrollable before it overlaps (dependent on the display size).
Updated JS fiddle, try this, i have updated CSS part in your code
https://jsfiddle.net/wp3wvuj2/2/
.main_input {
width: 209px;
top: 70px;
margin: auto;
margin-bottom:30px;
/* position: relative */
overflow: auto;
height:216px; //Give some height always to apply overflow auto
}
.main_start {
width: 100%;
margin: auto;
/* position: absolute */ //Not required
bottom: 20px;
font-family: Pamela;
font-size: 36px;
text-align: center;
}
I've only changed the styles on class main-input
.main_input {
width: 226px;
height: 234px;
top: 70px;
margin: auto;
margin-bottom:30px;
position: relative;
overflow-y: auto;
}
EDIT:
Please note for this solution to be able to work, I needed to remove the Top and Bottom positions of some elements as they were breaking the layout. Please use Margins or Paddings to get that styling you desire.
This now works to scroll once the space runs out on the page.

Center an Image Vertically in a Fixed Position Div

There are tons of questions on SO regarding vertical alignment, but I haven't discovered a clear answer to my problem.
I created a fiddle to show exactly what I'm trying to do.
HTML:
<div id="fade"></div>
<div id="fullscreen">
<img src="http://jira.seraphdevelopment.com/jmajewski/clean/uploads/pictures/n8jvxzd2476480d0.jpg" />
</div>
CSS:
#fade {
/* Cover the entire viewport. */
position: fixed;
top: 0px;
right: 0px;
bottom: 0px;
left: 0px;
/* Transparent Background */
background-color: #000;
opacity: 0.50;
}
#fullscreen {
/* Cover the entire viewport. */
position: fixed;
top: 0px;
right: 0px;
bottom: 0px;
left: 0px;
}
#fullscreen img {
/* Adding the display: block allowed me to center
the image horizontally with the margin: auto. */
display: block;
margin: auto;
/* Limit the size of the image. */
max-width: 80%;
max-height: 80%;
/* This didn't work for me. */
vertical-align: middle;
/* This didn't do anything, either. */
line-height: 100%;
}
I am trying to make a lightbox of sorts, such that the user will click on an image on the page, causing that same image to load up in fullscreen mode. The first div, fade, will be used to cover the entire page with a semi-transparent black background, essentially giving the effect of the page fading away, while also making things modal.
I wanted to be able to nest the image inside the fade div, but I ran into a problem. Setting the opacity on the outer div (to create the fade effect) caused my nested image to inherit the opacity value. Thus, I added a separate div that was identical to the first one, except without the background, and nested the image inside of that.
For the record, I did manage to figure out a workaround to the opacity issue, but I haven't yet implemented it. Credit to Blowski, a SO user who posted this answer to a question regarding opacity:
I do not want to inherit the child opacity from the parent in CSS
The long story short, I have tried quite a few things now in trying to get this image to be centered vertically, but to no avail.
Keep in mind, this solution needs to work with any image!
I am certainly capable of adding a line of code to the $(window).resize() function to center the image manually, but I would like to avoid doing so, if possible. I'm very curious to learn a way around this, as I seem to run into these types of issues more often that I'd like.
Bonus: Why is vertical alignment so difficult for a browser to perform?
Here is one way centering an image in a fixed/absolute positioned div using CSS.
#fullscreen {
/* Cover the entire viewport. */
position: fixed;
top: 0px;
right: 0px;
bottom: 0px;
left: 0px;
}
#fullscreen img {
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
margin: auto;
/* Limit the size of the image. */
max-width: 80%;
max-height: 80%;
}
The trick is to use position: absolute for the img and set all the offsets to 0, and then margin: auto will center the image.
The max-width and max-height values will work as expected.
The reason this works is that the image has intrinsic dimensions, so the CSS engine has specific values to do the necessary math to center the images both vertically and horizontally.
See demo at: http://jsfiddle.net/audetwebdesign/KG99S/
Comments
Note that this technique works independently of the overlay.
Also, this works regardless of the aspect ratio of the image.
Reference
This technique follows from the CSS2 specification regarding how the horizontal and vertical margins are determined for absolutely positioned inline, replaced elements.

How to reveal element by scrolling?

I'm trying to make an effect similar as used on http://www.t-mobile.com/ , when the user scrolls down to the bottom of the page they reveal the "footer" more and more as the user keeps on scrolling.
I've tried to search both here and on google but haven't been able to find anything that's really useful. Most examples only shows/hide the footer once the user scrolls to the bottom.
So my question is, what's the effect called to reveal an element by scrolling? Are there any good tutorials / blog posts about this? All help I can get is much appreciated!
As I commented, you need to make your element fixed, so as explanation goes, I have two elements here, one is a normal position: relative; element, so nothing fancy about that, I assigned relative so that I can make the z-index work
Second element is positioned fixed and also, make sure you use margin-bottom which should be equal to the height of your footer, no need to assign any negative z-index whatsoever to this element.
Demo
Not much HTML ...
<div></div>
<div>Reveal Me</div>
CSS
/* These are for your main site wrapper */
div:first-child {
height: 800px; /* Even auto is fine, I
used fixed height because I don't have any content here */
background: #eee;
margin-bottom: 200px; /* Equals footer wrappers height */
z-index: 1;
position: relative;
}
/* These are for footer wrapper */
div:last-child {
background: #aaa;
height: 200px;
position: fixed;
bottom: 0;
width: 100%;
}
For Dynamic Sizes
Note that am using a fixed height for the fixed positioned element, if you have variable height in footer element, than you need to use JS or jQuery to calculate the height using
$('#wrapperElement').css('margin-bottom', $('#footer').height());
Here, the selectors of #wrapperElement and #footer are my assumed ones, you can replace those with the your own selectors.
Something about fixed element - Horizontal Centering (I think it will be helpful to some users)
When you will make your element fixed, it will get out of the document flow, so if you are assigning fixed to the wrapper of footer element and want to center some content in there, than nest another element inside that wrapper and use width and margin: auto; for that...
Demo 2
HTML
<div></div>
<div>
<div>Reveal Me</div>
</div>
CSS
body > div:first-child {
height: 800px;
background: #eee;
margin-bottom: 200px;
z-index: 1;
position: relative;
}
body > div:last-child {
background: #aaa;
height: 200px;
position: fixed;
bottom: 0;
width: 100%;
}
body > div:last-child div {
width: 80%;
margin: auto;
outline: 1px solid red; /* To show that element is horizontally centered */
}
Note: Selectors used in this answer are too general and are good for
quick demonstration purposes, in real projects, make sure you use
specific selectors

div shift to left with page loading

I'm working on this site egtripper.com and with page loading the slider section float to left instead of be in the center, see this image and when I try to inspect element with google chrome tool this problem disappear and the page be as expected see this image
this is the css code for the slider div
.slider {
width: 1000px;
height: 330px;
margin: 30px auto;
overflow: hidden;
min-width: 980px;
position: relative;
}
can any one help me solving this issue
Add to .wrapper css style
.wrapper{
text-align:center;
}
slider element has a set margin 0 auto so it is necessary to have more momentum to center the elements inside the wrapper

Fixed background image horizontally connected to content with fixed width

The problem is: I have a huge background image and content with those characteristics:
the content is centered with margin: auto; and it has a fixed width
the position of the content is in relation to the image (like it fits in the middle of the image)
this connection is only horizontally (vertical scrolling moves everything around as expected)
This works fine, actually, on desktop devices with position fixed on the background image.
But the problem is: When I resize the window until it's smaller than the content, the content is fixed on the left side, but the background image is still centered, as expected. In this case the connection between both elements gets lost.
I have this JavaScript that does the trick, but this is of course some overhead I want to avoid as it isn't smooth anytime due to the calculation:
$(window).resize(function(){
container.css('left', (body.width() - img.width()) / 2);
});
I also tried things like that:
<div id="test" style="
position: absolute;
z-index: 0;
top: 0;
left: 0;
width: 100%:
height: 100%;
background: transparent url(path) no-repeat fixed center top;
"></div>
But this results in the same issue described above.
Is there any elegant CSS solution for this problem?
Demo
Try it yourself
NOTE
The image size is fixed and known and it never gets scaled by the browser.
Is this working for you? http://jsfiddle.net/wPmrm/24/
HTML
<div class="background">
<div class="content">
CONTENT
<br><br>
This example works fine until you the viewport size gets smaller than this content. After that the image isn't sticky anymore.
<br><br>
And check out vertical scrolling.
<div style="height:1500px;"></div>
END
</div>
</div>
CSS
div.background {
min-width: 740px;
background: url('http://placehold.it/1600x1050') top center fixed no-repeat;
}
div.content {
width: 700px;
height: 2000px;
margin: auto;
padding: 50px 20px;
background: none;
opacity: 0.7;
color: #333;
}
.background should be the wrapper for .content with a centered background and have a minimum-width of the .contents width+padding.
Update from comments:
http://jsfiddle.net/wPmrm/28/
We'll have to use a media-query, so when the width is at max 740px we change the background position. Oh and we set background-attachment to fixed again.
CSS added
#media screen and (max-width:740px) {
div.background {
background-position: -435px 0;
}
}
I don't see why it is -435px ((1600-740)/2 would be 430) but it seems to be the most accurate value.
