I'm working on a site for a client in which there's a background image that will be centered on the page with text, links, etc. overlayed.
I currently have the image resized as follows:
img.bg
{
height:100%;
position:absolute;
}
This fits the image to the height of the browser, but aligns it to the left. I need it to be centered.
Since I need it to be conditionally responsive to browser-height variations, the usual centering tricks aren't working.
Thanks!
Try removing "position:absolute" and adding margin: 0 auto. For example:
img.bg
{
height:100%;
margin: 0 auto;
}
or may be just place it inside a table <table align="center"> <tr><td>"image goes here"</td></tr> it's easier to manage cause you can add more items to the webpage in future without difficulty, add borders, change colours of tables, etc.
I can think of a couple ways to go about it (untested, so you'll probably have to tweak):
img.bg {
position: absolute;
/* Top and/or bottom for stretching it vertically as needed. Setting both will likely make it the size of the whole body, so beware. Remove bottom to keep it from doing that if necessary. */
top: 0;
bottom: 0;
/* Left and/or right for sizing/positioning */
left: 25%; /* Percentage position will make it adjust to browser window size, exact percent may need to be tweaked to get right and will depend on the image's size. */
}
img.bg {
display: block;
height: 100%;
width: 500px; /* Whatever your desired width is. */
margin: 0 auto; /* This should work as long as width is set. */
}
Depending on your exact design, either of these should work and be responsive to the size of the browser window. The second one is probably the most flexible and easiest to implement, since you don't have to fiddle with positioning.
The answer depends on exactly what you are after.
If you want an image displayed in the background of the website (which I think you are saying) then I am not sure what method you are using, but if you do away with your img.bg{} in your html and css, and just put the following into your CSS you will get what you want...
body{
background-image:url('background.gif'); // substitute background.gif for the correct file path
background-repeat:no-repeat;
background-attachment:fixed;
background-position:center;
background-size:auto 100%;
}

I'm trying to adjust the images and size depending the page size to doesn't go outside the grid, but I couldn't make it.
I tried add theses lines below in CSS but it bugged the others images
img{
width: 100%;
max-width: 800px;
}
The content should adjust the size of the image, but it isn't working
The image going outside the grid:
You can see the live preview here
Just give max-width for image to 100%
img {
max-width: 100%;
}
do the exact opposite you are doing
img {
width:800px; /* this is optional */
max-width: 100%;
}
OP's comment:
I already dropped it (the width:800px), but it messed with the images at right sidebar.
Then create a class something like img-resposive and for that class apply max-width: 100%. And use that class in images you want/need to
I suggest if you are trying responsive design, use 50em; instead of 800px
They are both equal (except when window is resized.)
Scenario:
In HTML, I have 2 element (top bar and images). The top bar need to be
at position:fixed (which will break the flow, I understand that). And
the 2nd element has margin-top to push down the image after the
"top bar". This has no issue until I minimised my browser width, the
content in the "top bar" push the container height and overlap the 2nd
element, which is the image. And this look ugly.
Anyway to have the 2nd element in flow with the 1st element, so that no matter how I minimised my browser width, the 2nd element is
smart enough to push down.
Code: CSS
.TopBar { /* 1st Element */
background-color: #000000;
opacity: 0.5;
width: 100%;
position:fixed;
padding:10px;
}
.TopBar > div {
color:white;
}
.carousel { /* 2nd Element */
display: inline-block;
margin-top:73px;
}
.carousel_img {
width: 100%;
}
Problem:
As you already know, you can't force position:fixed to flow, so there isn't an answer to your question to do it the way you want.
But the way you describe the problem, it's about supporting different browser sizes. If that's the case, then it sounds to me as if media queries are the answer to your problem.
CSS supports #media { ... } blocks, which allow you to specify styles that only come into play at certain browser sizes. So in order to solve your problem, you need to find out what browser width causes the layout to change (resize very slowly; it will flip out at a specific size), and write a media query that changes your stylesheet for sizes lower than that.
Without (a lot) more detail of your layout, I can't really give you specific code, but there are a lot of resources available online to learn about media queries if you don't already use them.
It's also worth noting that position:fixed can often be troublesome at small browser sizes, so much so that a lot of mobile browsers deliberately didn't even support it for some time. That's changed now, but it can still cause layout gremlins, so you may want to use the media query to switch it off entirely in low-width browsers.
Respond to answer given by Spudley on using the #media to solve the issue, I have try to find some page that has the effect of "fixed" & overflow element, and inspect the code by viewing it through web editor. And this is what I get. I slowly delete all the CSS and related element one by one till I got the "fixed" not working. And while the is still set on position:relative, there is a CSS that attached to it, which when I remove it, the "fixed" effect was gone.

If I understand what you want to achieve, there's a workaround to achieve similar results.
First, you effectively can't make your TopBar behaving like a flowing bloc element with position: fixed. So, let's make static.
The "fixed" behaviour will be provide by setting the body properties
body {
/* NOTICE the vertical flex box, makes the height adjust
automaticaly (no need to toggle)*/
display: flex;
flex-direction: column;
max-height: 100vh; /* Restrain the body to the window height */
overflow-y: hidden; /* Prevent scrollbar on body */
}
.TopBar {
display: block; /* Blocks have 100% widht by default, don't need to
specify */
padding: 10px;
position: static; /* No need to specify, it's the default value */
/* Helpers to make the TopBar easier to track */
background-color: #000000;
opacity: 0.5;
/* This is not part of the solution, it's only to make the height inversely proportional to window width
e.g. make it grow while the other decrease
*/
height: calc(200px - 10vw);
}
/*
Just under the TopBar, lets place a container element that will act
as scrolling window
*/
.container {
height: 100vh; /* max-height is superfluous because of the overflow. */
/* This will simply make the scrolling on the container instead of the body */
overflow-y: scroll;
}
.TopBar {
/* 1st Element */
}
.TopBar > div {
color: white;
}
/* simply to display some text */
p {
width: 50%;
margin: 1em auto;
}
Place your carousel inside the container and voilà! No need for position nor z-index fiddling. TopBar and container are flowing and the former will "push" the later.
That being said, some media query adjustments wouldn't hurt. According to your picture, elements in your TopBar are inlines (inline or inline blocks). You should consider making them "block". Flex-boxes would also worth some consideration.

I recently made a responsive layout, setting the..
max-width:100%;
property in google chrome, which works perfectly for adjusting the header image size, however, in other broweser's such as firefox, the image overlaps the parent container on the left size.
I am familiar with scott jehls picture.js polyfill, however specifying the image size for each screen size sounds like a headache inside the picture tags, is there any way to combat this in other browsers similarly to how google chrome resizes this naturally?
or at the very least, is there some kind of math formula for knowing the right picture size via the browser width? thanks.
You have set the max-height of img to 100%, however you don't have the width of it's parent defined. So, it becomes confusing to the browser to determine 100% of what thing.
Let's give the parent a width -
#headlogo {
width: 100%;
}
Also set the margin accordingly, you might wanna use margin: 0 for #headlogo.
Simply remove the h1-parent of the image and it works. (FF 32)
Try this one
max-width: 100%;
display:block;
height: auto;
Assuming you are trying to center the logo.
I would remove the float: right from the H1 and remove the margin you have. Than I would add a text-align: center to the H1. This will solve your responsive logo issue and keep the logo centered.
Your Current CSS
#headlogo {
float: right;
margin: 0 15% 0 0;
}
Proposed Solution CSS
#headlogo {
text-align: center;
}
My blog/website is iamdonle.com
An example of what I want is 13thwitness.com
The images on mine doesn't scale and a scroll bar will appear. On his website the images get smaller with the window. I'm sure it's simple but I'm a noob. Please help!
You images are scaling down, but your logo is not!
Try:
.logo {
max-width: 100%;
}
First, you'll need to make sure your container is able to scale. Right now it has a set width of 1150px, this needs to be either a max-width or percentage based.
First, remove the width declared on #container and add this CSS:
#container {
max-width: 1150px;
padding: 5px 30px 0;
}
Then you'll need to remove the width declared for your header. You can do this by either removing the line completely (line 82 of your CSS file) or by overriding it in your 'Custom CSS' field box in the Customization screen by doing:
#header {
width: 100%;
}
Then, as others have mentioned, you'll need to add a max-width to your logo as well.
#header img {
max-width: 100%;
}
Note: when I viewed the blog you were using the "Quite Big" theme, the code above only applies to that theme.
i'm currently trying to make an image resize depending on the browser dimensions. I've managed to get the image to resize horizontally, if I make the browser window narrow the image will resize proportionally just fine. However when I resize the window vertically, Firefox just doesn't seem to want to do it! The code is pretty simple
<body>
<div id="content">
<img src="images/abc.jpg">
</div>
</body>
and the CSS:
#content {
height: 100%;
padding: 50px;
}
#content img{
max-height:100%;
max-width: 100%;
}
Another issue is that the image does seem to resize vertically in chrome, but i have to drag the bottom of the browser well over the image before it start doing this. I'd rather the image start to rezise as soon as the bottom content padding "hits" the bottom of the image so to speak. Hope this is making sense.
Any help much appreciated
try this, taken from Twitter bootstrap 2
html,body{height:100%;}
#content {padding: 5%;}
#content img {
max-height: 100%;/* Part 1: Set a maxium relative to the parent */
width: auto\9;
/* IE7-8 need help adjusting responsive images */
max-width: auto;
/* Part 2: Scale the height according to the width, otherwise you get stretching */
vertical-align: middle;
border: 0;
-ms-interpolation-mode: bicubic;
}
Because height could potentially go on forever, you cant set the height of anything relative to the browser window to be a function of percent. What i'm saying is that you will need to put it inside of something with a fixed height to use a per-cent value. Good Luck!

You've only specified the "max-height" and "max-width" properties.
If you don't specify the actual "width" or "height" properties, the image initialy takes the width and height of its physical dimensions (if not larger than the specified max-height and max-width).
Said that, the behaviour you've noticed, is correct.
The answer is, as already mentioned, to specify also a initial width or height property, dependig wether your image is portrait or landscape.
Is that what you want?
I actually just added a height to html and body, so that #contents height doesn't get to high.
body, html {
height: 100%;
margin: 0;
padding: 0;
}
(And box-sizing: border-box to #content, because it seems like you'd want that)
