I'm trying to build a site with an initial 'landing page' look that you'd then scroll down from to see the rest of the content.
I can easily create a div that will fit the screen on the device I'm currently using, but how can I code for other devices of different screen sizes?
I've tried using '100%' which of course works initially but then continues to fill the screen when you scroll. I've tried defining a specific aspect ratio but again, that will only work for the screen I'm working on.
To be clear, I want the div, or img to fill the screen when a user first lands, then when the user scrolls the div/img should move up with the rest of the page.
I want to achieve this using only HTML or CSS.
Thanks in advance for any tips!
You can use vw and vh on the first <div> to fill the viewport. You can use this for reference: https://developer.mozilla.org/en/docs/Web/CSS/length
This'll do the trick:
.full-page-container {
width: 100vw;
height: 100vh;
}
vw and vh units represent a percentage of the viewport size. Hence 100vh will mean 100% of the viewport height and won't be affected by scrolling.

I'm trying to create a responsive web site. For that I found a nice looking template and adjusted it according to my needs.
One thing however came up where I couldn't find a solution so far - and that is resizing of images with different dimensions.
Let's say I have an image with a width of 600px and one with a width of 500px.
My screen size is 700px. I want both images to be shown at their native width (600px & 500px).
Now I reduce my screensize to 550px. I want the 600px image to be resized to 550px. No changes to the 500px image because the native width is still smaller than the screen.
Now I reduce the screensize to 400px. Both images should now also be reduced to 400px accordingly.
I've been googling and reading here for hours but could not find an automatic solution for this.
Best thing I found is is setting <img style="width:100%;max-width:xxx px;" where xxx is the original width of the image. But... I'd have to do this manually for each and every image!
Without max-width the image would always be strechted to 100% of the screen size.
As an alternative I found some JavaScript that calculates the original width of the image and could be used to fill out the max-width value.
If someone disables JavaScript (EG by using NoScript browser adddon) the whole thing wouldn't work.
Since I'm printing out my website using Perl I could do the calculation with Perl as well. That would help against disabled JavaScript. But still...
Are there really no better solutions? Do I really have to calculate the max-width for each and every image?
Here's the current work-in-progress: https://www.digioso.org/html5up-striped
The template features an image fit class that basically sets the width to 100% of the container and then I added the same image using width=100%;max-width=400px .
The image fit makes the image always use 100% of the screen which I don't want.
Thanks a lot!
Do not apply an explicit width or height to the image tag. Instead, give it:
max-width:100%;
max-height:100%;
check: How do I auto-resize an image to fit a 'div' container?
If you have something like this in your css:
img {
width: 100%;
}
The image tries to assume its actual size and is automatically adjusted accordingly with the container.
If you need to resize the image when your screen gets smaller, you can use #media and define the relative behaviour.
#media (max-width: 700px) {
img {}
}
I've been searching in other questions since this is a pretty common problem but none of them applied to my case.
I'm developing a small web app with React, just to get the basics, and the background img works fine in mobile view (there's a media query that changes it at 480px to a portrait one) it resizes from 480px to 320 and looks good.
The problem is that, at certain heights if you stretch or wide the window the background gets stucked in the middle of it (if you recharge the page it appears as it should, being the window in the same exact place as where the problem occurs).
The img is loaded through CSS in the html, If I remove the background-size property it works as expected in desktop and mobile, but when I cross the 1260px width it doesnt cover the full width.
I have this codesandbox with all my code: https://codesandbox.io/s/stoic-brahmagupta-ro2kb?file=/src/style.css
And I attach an image of the problem. Thanks in advance.
As u r testing this you can see the content of the App is overflowing the html element
I rather use min-height on global elements like body or html than static height to prevent such as cases.
So to fix it you just simply add
html {
height: auto;
min-height: 100vh;
To prevent not overflowing instead of scaling we just add min-height equaly of 100vh (viewport height).
I think it will propably do the job without height: auto; but i like add it to prevent even more edge casing
Im really struggling to articulate what im trying to achieve, please bear with me on this..
I've got a small "widget" on the left and side of my page.
This work fine on bigger screens.
For example, the widget is say 300px wide in the style.
However, If i load the page on a mobile or shrink the window, This becomes unfeasably small.
How do i get it to automatically change from 300px to full 100% width if a "smaller" viewspace is observed?
So say, i shrink my window , it would suddenly jump to be 100% wide rather than 300px? ( or similar)
Any ideas?
Sorry if I haven't explained it well enough. I've googled and nothing really sticks out that achieves what im doing.. maybe im not looking for the correct terms.. In a bit of a i dont know what i dont know to google it.
Cheers
What you're trying to say is "How can I make my website responsive?". You can do that with the CSS Media Queries. Check the link and google for more informations.
To give you an idea, just try this:
.my-class{
color: white;
background: black;
width: 300px;
}
#media (max-width: 600px) {
.my-class {
width: 100%;
}
}
<div class="my-class">
Some text!
<div/>
The break point here is at 600px, for large screens you have the width of the div is at 300px, for small screens you'll get the width taking 100%. (Try to resize the width of the current window while running the snippet to understand how it works).
edit: you can also use as the following style (the idea is in the min-width), if this is what you're looking for.
my-class{
width: 300px;
min-width: 100%; /* or 100vw depending on what you want */
}
Apparently,you are using the CSS-Unit "px". If you want to have a size relative to the screen, the units %, vw and vh would be useful.
% is relative to the parent element, which is probably the whole document, so you could work with that as a relative unit.
vh represents the percentage of the viewports heigth, so you could use it for the heigth of your widget
vw represents the percentage of the viewports width, so you could use it for the width of your widget
These were just some examples, if you want to learn more about the CSS Units, go to https://www.w3schools.com/CSSref/css_units.asp
I hope I could help you.
However, if you want to keep your px unit you can use the media query, as already mentioned by Il Saggio Vecchino. This allows you to have a different design at different devices.
Also take a look at https://www.w3schools.com/css/css_rwd_mediaqueries.asp
I want a page with a fixed pixel size to always have the same percantage hight. I cant just use % or any other relative units since I already made the whole site in pixels.
Means when I have a div with a hight of 1500px and view it on a 1366x768 screen the whole 1500px div should still be visable completely.
The effect I want to accomplish is something similar to a browser zoom.
You could try min-height: 1500px; on the div, then put overflow-y: auto on the body or html elements.
If you want something to dynamically resize depending on the window height you'll want to look into either CSS flexbox, using the vh sizing, or using javascript to detect window resizing.
You could use the viewport meta tag for that. Just remove the "initial-scale=1" part and the page should always be rendered to fit the screen.
You should note that this might result in the page being shown very small which can lead to problems when people want to access it with a smartphone for example. If you want to optimize your page for different devices and screens, I suggest you make yourself familiar with responsive webdesign.
Something like height: 100vh; would make the object's height 100 percent of the viewport height. It seems like there is no way around switching from px to something else.
I am trying to fix the web layout of my web page such that it does not resize or rearrange .
for example , check the page at http://www.boutell.com/newfaq/creating/fixedwidthlayout.html
. On my browser(chrome), when i resize the window along x-axis, the text rearranges to accomodate within viewable area.
On the other hand, http://msdn.microsoft.com/en-us/library/ie/dn255008(v=vs.85).aspx
when i resize the window along x-axis, the text does not rearrange to accomodate itself. I need my web page to NOT rearrange as in the latter case. Not able to isolate the attribute which controls this. I tried position:absolute in the body tag. No luck
You have a fluid layout. All your columns have their width set in percents. So, when the browser size changes, the columns's width changes too. Lets say one of your container has a width of 15%. When the browser window width is 2000px, this container's size will be counted as 15% from 2000px = 300px; on the other device, where width is 1200px, it will be 180px.
The fastest way to fix it to change width to px;
Another way is to set min-width property, - then the container can
act as a fluid, but at some point it won't go smaller. For example:
.columnt {
width: 15%;
min-width: 200px;
}
Hope you get the idea.
