I am using this code to auto resize images to the window size on a mobile page:
img {
width:100%;
max-height : auto;
max-width : 480px;
}
My intention is to show the image in the right size of the window on small screens and max 480px on bigger screens maintaining the ratio.
But for some reason i dont know when i use that code the text around the image goes behind it.
Theres a way to achieve this result using another method like Java or Jquery and avoid this problem?
If you do this for mobile devices I would recomend server resize to save download size.
Regarding the text that goes behind, do you have a more comprehensive testcase showing the actual document this CSS applies to?
You'll end up with squished images if you do that. I think this gives the best result you can achieve with CSS:
#content img {
width: 100%;
height: auto;
max-width: 480px;
}
I added this code in my page and it's working:
img {
width:100%;
max-height : auto;
max-width : 480px;
}
Have you tried using different style sheets for different screen sizes? Then you would just need to write the code for each situation and then load the needed style. It would also come in handy if you have other styles that need to change based on size. Very helpful on mobile sites.
<meta content="width=device-width, initial-scale=1.0" name="viewport">
helps to make sure it scales right. Not sure how helpful it will be, but hope this link helps.
CSS trick for specific style sheet
I've also played around a little, and it seems to work if you set the image as a percentage. I floated one to the left of text and at 50% of the screen and it re-sized text and all. If you need me to post an example, just ask.
use #media to do manual change by the mobile, tablet or desktop size.
by the way mobile and tablet will have landscape and portrait. if you using google chrome to check you can determine it better. sample of website : Media Queries: How to target desktop, tablet and mobile?

I googled for 2 days trying to understand how the auto height fit works, I think I understand in how to make a background fits the browser, but with this banner slider, I don't have a clue.
Could someone please enlighten me on where should I look for/start? Should it be a CSS or JS?
I'm very new to HTML5/CSS3, Wordpress gave me a very easy environment to start a website, but I just barely know how to modify a website other than a plugin.
It would be very cool if the slider section to fit like this one below
Thanks in advance!
This should set the image/album you have on the homepage to be the height and width of the browser, tweak some of the CSS and it should line up with the Sidebar perfectly like you wanted.
img {
max-width: 100%;
height: auto;
width: auto\9;
}
If you are looking for the image that fits the browser height regardless of any display then you can use 'vh' unit from this css units page.
vh means viewport height[viewport = the browser window size.], and 1vh = 1% of the height of viewport, so in your case you can use 100vh for image like this:
img{
height: 100vh;
}
Check this jsfiddle for the same.
Remember that you need high-resolution images and those images will not look good on mobile devices.
I am working on a site for a client, using a purchased Wordpress theme (so all the code is not necessarily mine, but I can pull something if needed).
The landing page has a responsive background image. On top of that, I need to use images to show the relevant logos (the fields where I input this were intended for text, but they allow images with no problem). The image has a border wrap around it also, and then people can scroll down from there to see the rest of the content.
My problem: on desktop, the logos will rescale with the WIDTH fine. But one of my clients is viewing in a very widescale-oriented browser window (which I figure is unusual across all users, but it's the client!), and the logos do not rescale with HEIGHT changes, so they get cut off by the border wrap.
I've tried things like
.home-section img {
max-height: 50%;
}
Which is what the theme's developer provided initially, and also changed 50% to 50vh (just trying some things I came across online, not a code expert by any means), and also a variation of this solution HERE
with no luck.
My (again, partial) understanding is that since the height of the div with the background image isn't set explicitly, I can't use a percentage height for the logo/child element, but is there a way to solve this?
I'm currently using srcset to get the logos the right size for mobile, but that's not a perfect solution. I figured there may be a javascript solution too, but I'm only about 75% with HTML & CSS and not much with JS/PHP without explicit directions. (Call it capable, but inexperienced).
You can view the issue HERE.
Thank you!
=================================================
EDIT:
A coworker came across this solution, which improves things greatly. The issue still happens at a short enough browser (IE landscape phone viewing, etc), but works on a greater range of viewport sizes:
div.home-section-image {
min-width: 600px;
max-width: 1080px;
min-height: calc(690px * (90/150));
height: 100vh;
width: 100vh;
}
The logos now scale vertically to a point, though the viewport height can still catch them and cut them off, but at a better threshold (at ~550px high, where it happened at ~720px high previously - now well beyond a normal person's minimum browser size, my understanding is ~760px is average).
I tried to combine this with #kburgie's code suggestions to keep the logos completely above the green border, but my results ended up pushing the logos off the TOP of the page instead, which is worse (for me, on a horizontal Galaxy S3, I can at least get the main square of the top logo to display, which is enough for me at that size).
Thanks to everyone who helped - I think this may be the best solution I can pull for now!
Seems like you should be able to combine width and height media queries to catch that edge case:
#media (min-width: 1200px) and (max-height: 500px) {
.home-section img {
height: 200px;
width: auto;
}
}
I don't have enough rep to comment or I would. I think isherwood's media query is too specific.
Responsive images should already be responsive by height AND width, and the best way to handle that is by working with the image width.
This is a dangerous selector and you should get rid of it:
img {
height: 100%;
width: auto;
}
It will affect ALL images on your site. You should use a class instead. Beyond that, your images are already set to max-width: 100%, which is all you need.
Focus on your positioning instead
Step 1: Remove your margin top and bottom
.home-section .container { margin: 0 auto; }
Step 2: Absolutely position the image container at the bottom of it's parent. Then it will always stay above the green border. Stick it in a media query if you'd only like this positioning above a certain screen size.
.home-section-image {
position: absolute;
bottom: 10px;
}
I am new to HTML and CSS development. I have created a html which looks fine on PC web browser.
However, when I use my Android cell phone browser to view it, since the cell phone screen is too small, there is a lot of sliding needs to be done to locate the area I want to bring into focus.
My webpage only has an index table in the center, while left and right of the body are all blank. I was thinking if there is any way to detect the browser to see if it is from a mobile device, then resize the body of the page?
Any advice is welcomed. Thanks in advance.
It is either:
you should take a look and learn at some responsive website code like this one.
Try to add this code after your opening head tag <meta content='width=device-width, initial-scale=1' name='viewport'/> if you don't want horizontal scrollbar on smaller screens.
The most popular method today is to use a CSS media query. Any code inside a media query will only apply to the parameters specified. This usually applies to height and width of the browser but it can also work for printed stylesheets, display resolution, and a few other things.
Heres an example that targets browser widths between 320px and 480px, common sizes for smartphones.
#media only screen and (min-device-width : 320px) and (max-device-width : 480px) {
body {
background: #999;
width: 100%;
}
}

I've been searching the questions here for weeks and haven't found an answer to this, so here it goes:
I created a fairly large image (800x1000px) to be displayed in the center of my site. I made it so large with large screen resolutions in mind but I've been using the CSS max-width: 100%;
max-height: 100%;
to have it resize proportionally to fit on computers with smaller screen resolutions as well. (keep in mind this is not a "background" image)
However, what I'd really like, is for the image to resize only when keeping it at the current size would create a horizontal scrolling bar in the user's browser. However, if it will only make a vertical scrolling bar, I'd like it to not resize the image, that way it can be as large as possible (the reason being that I feel a horizontal scroll is less professional looking than a vertical scroll as most sites have a vertical scroll anyway).
Is there a way to accomplish this with CSS or will I need Javascript? And if I'll need javascript please spell out the code as I have absolutely no experience with javascript, thanks!
Just remove max-height: 100%, leaving only the max-width: 100%.
Demo
img {
max-width: 100%;
height: auto;
}
I have a website where in the desktop version a sidebar is shown containing 10 to 20 small images. Until now, on mobile devices this sidebar was simply hidden with a display: none, which is the least performant solution since all the images will be loaded anyway.
I'm now wondering what the best way is to disable the sidebar completely on mobile devices (without using a separate AJAX request).
The best solution I could think of is the following:
Write the HTML code of the sidebar into a JavaScript variable
test the device width by checking a media query with JavaScript (e.g. using Modernizr.mq or so)
if this test yields a non-mobile device, write the content of the variable into the DOM, for example by using innerHTML, jQuery.append, jQuery.prepend or similar
I know that RWD performance can sometimes be a very complicated topic and that the most performant solution is often not obvious. So can anyone think of a better solution than the one presented above?
If you don't want the images to load on mobile, instead of placing the images as <img> tags, you could set divs to the desired width and height and bring the images in as background images. In your css, hide the sidebar by default. Then, at whatever width you deem to be beyond mobile, use media queries to display the sidebar and load the background images in the divs.
#sidebar {
display: none;
}
#sidebar div#sidebar-img-1 {
width: 100px;
height: 100px;
}
/* ... */
#media only screen and (min-width: 480px) {
/* display sidebar */
#sidebar {
display: block;
}
/* set background image for sidebar items */
#sidebar div#sidebar-img-1 {
background-image: url("sidebar1.jpg");
}
/* ... */
}
The drawback is that by placing content in the stylesheets, you're trading performance for semantics.
I was just doing some research on how to do this and ran into this by the filament group:
https://github.com/filamentgroup/Ajax-Include-Pattern/
Seems easy to set up. It works off of what looks like media queries set in data attributes.
So a sidebar you don't want to appear on mobile would look something like this:
<aside href="..." data-append="articles/latest/fragment" data-media="(min-width: 40em)">Possible Mobile Content</aside>
So your sidebar would only come in on a screen that was at least 40ems (~640px) wide. Of course you also need the javascript file and to initiate it, but those look fairly simple as well.
