I'm using font-awesome for my loading notification, but it's driving me crazy that there is just a slight offset causing the rotation to have a "wobble"
html
<div class="loading-div fa fa-cog fa-spin"></div>
css
.loading-div{
position: absolute;
z-index: 9999;
font-size: 200px;
}

I noticed that it's containing div is not square, but if I try to set height, width to static pixels it only gets worse... thoughts?
As you said yourself, the div isn't square so that's going to give you a bit of "wobble" as it rotates. Set the line-height (rather than height) and width properties to equal values and set text-align to center and it should smooth things out a bit for you.
If it you're still getting a slight "wobble" then it may just be a rendering issue in your browser. Font Awesome is, I believe, optimised to be displayed at 14px, or multiples thereof, so try reducing the font-size to 196px.
Here is an updated Fiddle with 2 animations, the first with the dimensions set and the second with the dimensions set and the font-size reduced.
And here's an extract with the properties relavant to the "fix":
.loading-div{
font-size:196px;
line-height:200px;
text-align:center;
width:200px;
}
To center horizontally, use this (relevant CSS):
.stripes{
text-align: center;
}
.loading-div{
display: inline-block;
}

I am working on a back button for my website, I am not too sure how to make the button smaller. I tried adjusting the font size applying negative padding, etc. But to no avail I was able to get the button size to shrink while maintaining its round shape. Below is the CSS which I had applied on my button.
.fa-arrow-left{
font-size: 2em;
height: 100px;
width: 100px;
border-radius : 50%;
position: relative;
}
I am looking to strink the button to about 50% of this current size while maintaining the round shape as well. Appreciate any help on this. Thanks.
The detail you are giving is not really satisfactory. Try changing the width and height properties to lower values. If that doesn't help, you can use transform: scale(.5); but that is more than suboptimal.
If you are using font-awesome (as the fa-prefix suggests), changing the font-size should do the trick.
Try to change
height: 100px;
width: 100px;
As height and width are usually the parameters determining the size of your html elements.
You already set border radius to
border-radius : 50%;
So this will be applied no matter the size of your element.

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;
}
I've been making a responsive image thumbnail gallery for a portfolio using this "Tutorial".
This tutorial is quite complete and pedagogic (I'm a big noob), but doesn't cover one part: The tutorial maker uses images that are all in landscape style.
For my portfolio, the thumbnails are going to be alternating both landscape and portrait oriented images.
Using both kinds of orientation gives a sort of an unordered look and feel to the divs, which isn't what I'm going for.
A simple way to solve this would be to manually crop portrait images to fit landscape style. It's kind of an archaic technique I'd rather not resort to.
I realize that another way to do this would be, not to use the img tags, but rather using background-image and background-contain on divs fit to the image box. Something I'd rather not do as it would mean creating a new css class for every thumbnail (I think, not sure)
Someone had the same sort of problem, but he uses jquery to fix it. Since I'm learning css, I think it might be better for me to try and fix this problem using only css.
"Link"
My major constraint is that I want the page to stay responsive, as well as have my images keep their aspect ratio, so a width:100% and height:100% is out.
If you'd like me to make a fiddle, just ask and you shall be given.
Thanks for reading, hope I made myself clear, English not being my primary language.
EDIT: Here's a fiddle showing how the <img> <div> and the css are. http://jsfiddle.net/R8B27/ (I suggest resize the "result" box to exactly see how it messes up)
L.
The main issue here is the vertical alignment of images that are cropped (in your case portrait orientated images).
If you can go with default alignment of these images, this means only the top of the image is shown, you can use this technique :
FIDDLE
The CSS I added/modified from your example :
.galleryItem a{
display:block;
position:relative;
padding-bottom:50%;
overflow:hidden;
border-radius: 5px;
}
.galleryItem a img {
position:absolute;
width: 100%;
height:auto;
display:block;
}
I had a similar situation in which the solution needed to be inclusive to both portrait and landscape pictures. This was my solution:
min-width: inherit;
min-height: inherit;
max-height: 63vmin;
object-fit: cover;
The parent object was a circle with a 'vmin' responsive size, therefore the 'vmin' 'max-height'. 'Inherit's were used to always fill the parent object and 'cover' on 'object-fit' to not lose proportion. 'Max-height' was used as the control factor due to the rarity of portrait pictures exceeding a 1:2 ratio; meaning to control the excess of width cutoff through a height variable.
As for positioning the image inside the div, I recently found the use of this excerpt very useful:
margin: 0;
padding: 0;
-webkit-transform: translate(-50%, 0%);
position: absolute;
left: 50%;
top: 0%;
With 'margin' and 'padding' at '0', you're cutting off excess weight on the pic. '-webkit-transform: translate' will allow you to change the item's origin or pick point. Setting this to '-50%, 0%' will set the origin to the center-top of the pic (this should always have negative values for the origin to be inside the item). 'left: 50%; top: 0%;' will set the placement of the origin of the item to be at center-top of the container.
In all latest browsers(supposing your not using IE anymore) you can use "object-fit" for this purpose. just add this css:
.center-cropped {
object-fit: cover;
object-position: center;
height: 200px;
width: 270px;
}
...
And in html, you can use this class directly in the img tag:
<div>
<img class="center-cropped" src="~/Images/yourImage.jpg" />
</div>
This will show only a "centered" version of your image, for both portrait and landscape images
please check out the codes first:
html:
<!DOCTYPE html>
<html>
<head>
<title>hello</title>
<link rel="stylesheet" type="text/css" href="style.css" />
</head>
<body>
<div id="container">
<div id="menu">
HOME
</div>
</div>
</body>
</html>
css:
#container
{
width: 80%;
margin: auto;
height: 450px;
}
#menu
{
background-color: #1b9359;
height: 25%;
}
.button
{
text-decoration: none;
float: left;
font: bold 1.2em sans-serif;
line-height: 115px;
margin-left: 20px;
display: block;
text-align: center;
}
.button:hover
{
background-color: #2cd282;
}
so what i would like to acheive is that when i hover to the home button, the whole div changes color, and does not get distorted or mispositioned on zoom. one answer told me that i could use display: block, but that it does not work as you can see. however, i did manage to make it work with display: block when the menu pane is like a vertical column and not a horizontal one. could anyone pls explain why this happens, and how display property of css affects that element? and how to achieve the full highlight without zoom distortion?
If you use percentages as your height and/or width then it will be a percentage of the parent container.
If you want your page to behave well when using a zoom, ie. ctrl + mouse wheel up or down, size everything in your page using em. 1 em = 16px by default. Just get used to using em. Get a calculator out and start converting things. Trust me, it's worth it to have a page that zooms straight in in out without jumbling.
Your outermost container may use percentages as long as you're using an auto margin for the central contents this is an exception to using em, that way things will still be centered on all resolutions. When I say outermost container, I mean body...
Before I tell you how to make it work I'll answer the other questions:
"...I did manage to make it work with display: block when the menu
pane is like a vertical column and not a horizontal one. Could anyone
pls explain why this happens, and how display property of css affects
that element?"
Block elements stack on top of each other vertically. This means that in a vertical arrangement if the zoom level is changed, those elements are perfectly at home taking that extra space up to the right side. Now, if they are intended to be lined up horizontally, display block will not work because that is simply just not what it does. Display inline-block will stack them horizontally preserving heights and widths set for the container, and to my own dismay, adding tiny margins between elements unlike the use of float, which would be touching the previous element, but float is definitely not something I would recommend for a nav menu.
Let's say you have your first link, and it is display:block. It will start its own new horizontal line, assuming there is not a float:(side) item before it with extra space to fill. In that case, you would add clear:both(or :left/:right) to overcome this. Now let's say you want to add a second link to the right of the first one which is display:block. The second one could be display:inline-block, and it would be on the same level as the first one, but if you did this the other way around, the second one, which is display:block, would start on its own new line below.
Now, to make your button do what you want it to do:
I will assume for the purpose of giving you a good answer that screen width in pixels is 1280px. So 80% of that is 64em. That is (1280px * .80)/16px = 64em because 1em = 16px. As I mentioned before, we do this to make your site elastic when it zooms.
You've previously designated #container as height:450px; So let's convert that. 450px/16px = 28.125em (em values can go to three decimal places, but no more) This is good, so we have an exact conversion, and not a rounded value.
container is now finished and should be as such:
#container
{
width: 64em;
margin: auto;
height: 28.125em;
}
Next change height in #menu. You have it as height:25%. That is 25% of 450px/or/28.125em If we leave it at 25% it will mess up the zooming. So let's convert. 28.125em/4 = 7.03125em
This time we must round to 3 decimal places. So we get 7.031em.
menu is now finished and should be as such:
#menu
{
background-color: #1b9359;
height: 7.031em;
}
Next is your button class.
.button
{
text-decoration: none;
float: left;
font: bold 1.2em sans-serif;
line-height: 115px;
margin-left: 20px;
display: block;
text-align: center;
}
At this point I lose some of my own certainty about how CSS will react, but I will start with this. Do not use float:left and Display:anything together. In this case, use display:inline-block. Get rid of the float:left. I am not sure why you have a line-height set. I am guessing it is your way of attempting to set a height for your button because it is 2.5px larger than the height of #menu (line-height of .button = 115px, height of #menu = 112.5px which we have already converted to 7.031em). If that's what you're trying to do you're doing it wrong. get rid of line height, and make it the same height as its container so that it fills it. height:7.031em;
I'll assume if you're making a horizontal menu, that you aren't trying to make one button take up the entire width. If you do not give it a width, it will fill the whole row. I'll be bold and guess you probably want your button somewhere in the ballpark of twice as wide as it is high. Let's just go with 15em(240px). width:15em;
Last is margin-left... 20/16 = 1.25em. Cake.
Now we have:
.button
{
text-decoration: none;
font: bold 1.2em sans-serif;
height: 7.031em;
width:15em;
margin-left: 1.25em;
display: inline-block;
text-align: center;
}
Keep in mind that block elements, whether inline or not, have little built-in margins on top of the margin-left that you've added.
If you make these changes, your page should zoom beautifully and your link will fill out its container vertically, but be a specified width to keep it clean. Never use px or percentages if you want to avoid zoom slop. The body container is 100% by default, but it holds everything and therefore the things in the center seem to grow outward toward the edges and therefore do not show any visible effect from the body not being set based on em, and it also makes the page naturally friendly with a variety of screen resolutions.
I hope this helps.
Edit:
As I mentioned, I lost some of my certainty. The line:
font: bold 1.2em sans-serif;
Does something that makes the container be larger than 7.031em removing that line fixes the problem, but I do not know the remedy if you insist on a font size of 1.2em. I tried setting height to 6.831em instead of 7.031em and it did not do the trick.
A few more tips:
1) If you still feel that you need a margin, perhaps margin-right would better suit you so you don't have random slack space to the left.
2) The CSS I provided does not adjust for the vertical alignment of your link text; to fix it add line-height:7.031em; to the .button class. Note: this method only words with single lines of text!!!
I have two div's:
<div class="iphonebackground">
<div class="screenbackground"></div>
</div>
.iphonebackground {
background-image:url("../img/iphone-frame.png");
background-repeat: no-repeat;
background-position: center;
background-size: 100%;
height:576px;
}
.screenbackground {
background-image:url("../img/iphone-background.png");
background-repeat: no-repeat;
background-position: center;
background-size:100%;
height:576px;
}
The first, iphonebackground has background-image set as an image of an iPhone frame (http://chpwn.com/apps/iphone-frame.png). The second, screenbackground has background-image set as PNG image the same size which holds the image of what would be on the iPhone's screen (https://dl.dropbox.com/u/290586/iphone-bg.png).
The result of this is that the page renders something like this: http://imgur.com/yVF9gyg. As my site is based on the Twitter Bootstrap the div's resize to fit the browser window so on a smaller display it looks something like this: http://imgur.com/Q2Qy4wn.
As you can see, the height of the div is fixed at 576px. This means that in the second image there is a large blank space above and below the background-image. Is there a way to set the height of the divs so that they are as high as the size of the background-image's height, thus removing the blank space?
A background image has no effect on the size of the DIV to which it is attached. The size of that DIV will be determined by its content, or by width and height if explicitly set in your CSS.
If you have a DIV with a % width (i.e. unknown pixel width), then you cannot set the height based upon this unknown width without resorting to JavaScript, or... the new CSS calc() function, where you could specify the height as a ratio of the unknown width and let the browser work it out. See https://developer.mozilla.org/en-US/docs/Web/CSS/calc for more.
Support is getting better (78% according to caniuse.com) but you can't rely on it.
[edit] While looking for a solution myself, I found an excellent hack using padding-top, written by user Hasanavi in answer to this question [/edit]
You can try using line-height css property on your div.
line-height: normal;
line-height: 3.5; /* <number> values */
line-height: 3em; /* <length> values */
line-height: 34%; /* <percentage values */
line-height: 50px; /* <Pixel> values */
line-height: inherit
Hope this helps...
You can use
height:auto; in both
