I am working on a WordPress website and have styled the templates header in CSS. I've given it a different background image and it's working, the only problem I have is on mobile.
On mobile there seems to be a white gap to the right of the image and I was wondering if anyone knows a solution to this?
You header element—
<header id="home" class="header menu-align-center" itemscope="itemscope" itemtype="http://schema.org/WPHeader">
</header>
has a min-height:100px set. Increase that number until the image goes all the way across. Try 112px.
For images I learned for myself that it works best to define the container using an aspect ratio, so that it's forced to take up the space you want it to. And then make the image position: absolute inside the container and force it to fill the parent container using object fit: cover and set both lengths to 100%. The image will then automatically fill 100% height or width whatever of both is required:
<div class="image-container">
<img src="...">
</div>
.image-container {
&:before {
/* create a 1px bar inside the container and stretch it according to padding-top */
content: "";
width: 1px;
margin-left: -1px; /* 1px bar with -1px margin will make sure no space is taken */
float: left;
height: 0;
padding-top: 50px / 150px * 100%; /* height / width ratio. So this would result in 3x as wide than high. 100% always refers to the width of the container which makes this trick work */
}
&:after { /* to clear float */
content: "";
display: table;
clear: both;
}
img {
position: absolute;
width: 100%;
height: 100%;
object-fit: cover;
}
}
You can then also make the container switch aspect ratio by simply changing the .image-container:before{padding-top:;} in your media queries.
Also note that at best the <div> container would be replaced with a <picture> tag providing some different image sizes. Then you have performance increased and no extra DOM nodes as you need the picture tag anyways.

i'm with a trouble in relation with treatment of image, using intervention image on laravel. The problem is: I have to change aspect ratio of a image, but, in my current way, i'm cropping the image to do it, and important things in this element is being cropped too. So, i was wondering, is it possible add border around on image to create the aspect ratio? If you all would can help me, i'll would be very glad with that.
P.S. Sorry for my english, i'm still learning, haha.
Solution 1
Create a div with the right aspect ratio/dimensions and load the image as a background image with background-size: contain.
div {width: 300px; max-width: 100%;}
div > div {
width: 100%;
padding-bottom: 60%; /* use this for the aspect ratio */
background: black url('http://jekyllcodex.org/uploads/grumpycat2.jpg') center center no-repeat;
background-size: contain;
}
<div><div></div></div>

How it works
The padding bottom creates the height for this div (as it has no content). The padding-bottom percentage is the percentage of the width of the parent. Thus, a 2:1 ratio image has a padding-bottom of 50%. A 3:2 ratio image has a padding-bottom of 66.66%.
Why this works
The div inside this div has a width of 100%. This is 300px, as the child div is constrained by its parent. The padding bottom percentage is relative to containing block, and not (as many people think) to the body. Here the containing block is the nearest block-level ancestor, which is the parent element. Note that it would be relative to the body if we used just one div with a fixed width of 300px.
Why this solution is not perfect
This solution is fully responsive, due to the max-width of 100% on the containing div. And if you change your mind and you want images to be cropped instead of contained, you only need to change the background-size to 'cover'. Therefore this looks like a good solution. However, a background images is not a proper image, as it has no 'alt' text and lacks a DOM representation, resulting in all kinds of accessibility problems.
Solution 2
Create a div with the right aspect ratio/dimensions and load the image as img tag with max-width and max-height.
HTML
div {
width: 300px;
max-width: 100%;
position: relative;
}
div > div {
width: 100%;
padding-bottom: 110%; /* use this for the aspect ratio */
background: black;
}
div > div > img {
max-width: 100%;
max-height: 100%;
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
}
<div>
<div>
<img src="http://jekyllcodex.org/uploads/grumpycat2.jpg" />
</div>
</div>

About this solution
It works roughly in the same way as the previous one, but this solution is semantically correct. The difference here is that an image element is positioned absolute in the inner div. Its placement is absolute, but relative to its parent at 50% of the left border and 50% of the top. Then the image placement is corrected for its width and height, using the translate function of CSS (otherwise its top left corner would be in the middle of its parent). Because only max-width and max-height are used (and not width and height), the image stays responsive and keeps its aspect ratio.
On my front page I want the post thumbnail to be the full width of the page. But I only want it to be the full width of the page up until the image width it was uploaded at. So when the page gets bigger and bigger I want the image to stop being 100% once it gets to its actual image size and then just stay that size. Right now I have figured out how to make the post thumbnail full width, however as the page gets bigger the image just stretches to fit 100%. How could I fix this?
<?php the_post_thumbnail('thumbnail', array('class' => 'large-front-thumbnail')); ?>
.large-front-thumbnail {
position: relative;
width: 100%;
height: auto;
}
You need to make 2 changes.
Right now you're setting the image width to 100%. When you set width to 100%, no matter what size the image was uploaded at, it's going to stretch to the width of the container. You need to set width to auto.
You then want to set a max-width of 100%. Those 2 properties combined will mean your image will scale responsively yet never exceed the original upload size.
.large-front-thumbnail {
height: auto;
max-width: 100%;
position: relative;
width: auto;
}
As long as you haven't altered any of your WordPress defaults, the image size will always be 150px by 150px. How do you know? Because you are passing the 'thumbnail' argument into the_post_thumbnail.
Therefore, as #pol said, setting a max-width rule of 150px will work.
See more here about the behavior of the_post_thumbnail.
The following CSS should be what you require:
.large-front-thumbnail {
position: relative;
width: auto;
height: auto;
max-width: 100%;
}
Actually you just need use "max-height" & "max-width", preferable add div container outside constraint outer image size.
<div style="width: 100%;">
<img src="https://www.royalcanin.com/~/media/Royal-Canin/Product-Categories/cat-adult-landing-hero.ashx" alt="anything" style="position: absolute; max-height: 100%; max-width: 100%;"/>
</div>
I need to fit and crop the image into it's wrapper.
<div class="box desktop-3 tablet-3 tablet-ls-3 mobile-3">
<div class="inner-box fullbox">
<a href='#module'>
<div class="image-wrap" >
<img src="../img/placeholder.png" />
</div>
</a>
</div>
</div>
css
.box {
width: 282px;
min-height: 282px;
padding: 10px;
float: left;
}
.inner-box {
width: 100%;
min-height: 282px;
top: 10px;
right: 10px;
bottom: 10px;
left: 10px;
padding: 20px;
}
.fullbox {
padding: 0px;
}
.image-wrap {
...
}
i've tried to put the image as the background like you see below, but that didn't worked for me. I want to have a image section from the image that it fits into the box.
.image-warpper {
background-image: url(...);
background-repeat: no-repeat;
background-size: contain;
}
Do i have to crop the image via php or is it possible to scale or crop it in css?
Thanks
"Do i have to crop the image via php..."
Depending on the Image file-size its strongly recommendable to use PHP for this purpose.
Remember the clients browser will always load the complete image to resize it to the css given values.
So even if you got a style telling the image shall never exceed 100x100px the client's browser will load the full size image.
That could take "very long" if its a giant image (referring to the file size).
There are pretty nice classes/libs you can use with PHP to get a comfortable and easy way to play with images. And your page will be much faster then.
For example i recently found:
http://wideimage.sourceforge.net/
Super sweet thing. Supports chaining and stuff.
You should be able to do this:
.image-wrap img { max-width:100%; height:auto; }
This will constrain, and scale down the image, and set it to be 100% wide, according to however wide the parent element is.
Having in mind that you'll use an img html tag, make the image wrap div in position:relative and overflow:hidden and the image with position:absolute and height:100%, width:auto (or width:100% and height:auto). This way the image will be cropped in the parent container and keep its ratio.
See this demo and resize the frame to see how the image is cropped and resized in various dimensions.
I am looking for something that would allow me to render an uploaded image with a 3D perspective and a wrap effect like here.
This will be in the form of a cropping preview using a jQuery library such as jCrop
Currently I was able to achieve the 3D perspective using Reflex.js but looking for a more subtle solution with the wrapping effect as well.
Any help will be appreciated :)
Thanks in advance!
Your requirement of IE9 support basically mandates a canvas approach if you want to keep it client-side. You could of course do the rendering server-side and AJAX load the rendered image back in which will work in every browser.
If you decide that you can dump IE versions less than 10 (or at least just show them the normal photo without the transform then you can do the wrap-around effect with a combination of CSS 3D Transforms and CSS2 clip. Something like:
<!DOCTYPE html>
<style>
body { margin: 100px; position: relative; }
.edge { width: 20px; height: 196px; background-size: auto 100%; position: absolute; left: 30px; top: 2px; transform: perspective(600px) rotateY(-45deg); transform-origin: right; }
.panel { position: absolute; left: 31px; top: 0; clip: rect(auto,auto,auto,20px); }
.panel>img { width: 350px; height: 200px; transform: perspective(600px) rotateY(30deg); transform-origin: left; }
</style>
<div class="edge" style="background-image: url(my_image.jpg)"></div>
<div class="panel"><img src="my_image.jpg" /></div>
To break that down, we’ve loaded the user’s image and dropped it into the page, along with a div with the same image set as a background. That div is set to be a thin width and a height that’s almost as tall as the main image. We can use the background-size property to foce the background image to fit the div even if it’s taller.
We then absolutely position those two so that they’re next to each-other. The CSS2 clip property lets us clip off the left 20px of the image so that at this point the div and img look like one image together.
Finally, we set a perspective and transform-origin for each block and rotate them away from each-other around the Y axis. Because of the clipping we have to fudge the .edge block to be slightly smaller than originally (with a 200px tall image I had to drop it to 196px to look good) but that works pretty nicely for me.
Obviously you’d need to fill in the vendor prefixes (-moz-, -ms-, -o-, -webkit) and I’ll leave the shadow as an exercise for the reader (a simple background on the container would probably do).
Hello I have a header that I am trying to get working and I just got the menu working correctly, but now I can't get the size working properly.
The header is located at www.g-evo.com/header.php and what I want to do is shrink the grey a little bit so its more flush with the logo. I still want to keep those coloured boxes in the white however.
The CSS looks as such:
<style type="text/css">
#header-container {
/* centering for IE */
text-align: center;
}
#menu {
width: 950px;
/* centering for other browsers */
margin: auto;
}
#logo {
width: 950px;
/* undo text-align on container */
text-align: left;
/* centering for other browsers */
margin: auto;
border-style:hidden;
border-width: thick;
}
body {
width: 950px;
/* undo text-align on container */
text-align: center;
/* centering for other browsers */
margin: auto;
}
#headercolor {
background-color:#EEEEEE;
}
</style>
Thank you
I believe this is actually a matter of your HTML markup, rather than your CSS. You have two #logo divs (as a side note, you should only use each ID once per page), the second of which is causing the extra gray space you are referring to.
You should put /header_media/GTextured.png and /header_media/shapeimage.png in the same div, and align them next to one another, which should solve your problem.
For starters, you're using the "logo" id on two different items on the same page... that's not correct, since the ID attribute should be unique per element.
On the other hand, I don't really understand what you want, but if it's just to get the menu a bit closer to the logo, I'd add a class or change the id for the second div with the logo ID and set it a height of 20px, or so..
