How do I make a bottom fixed position menu in HTML? - html

I want to create a box-menu on the very bottom of the browser window.
It should stay at the bottom when the content doesn't fill up the entire screen
When the content overflows it should only be at the bottom when you scroll down (i.e. you can't see it if you don't scroll).
How do I do this?

I think what you are looking for is called a "sticky footer", and there are a couple of methods. I suggest you have a look at these sites:
http://ryanfait.com/sticky-footer/
http://www.cssstickyfooter.com/
Zoom in/out on each site in order to see how this appears when the content reaches the footer or does not.
Both methods fall short on one thing: They require you to know the height of the footer - but I have not seen any better solutions with only CSS.

How to build sticky scroll sidebar behavior similar to Facebook feed sidebar

I am working on building sticky sidebar behavior that will run alongside a vertical feed which is very similar to a facebook feed on desktop web. position: sticky works well for the easy use case where the sidebar is shorter than the height of the viewport. However if your sidebar is larger than the viewport the sidebar needs to have some scrolling mechanism so you can see the bottom of the sidebar as you scroll down the feed.
I am trying to recreate the facebook sidebar sticky scroll here.
The best way to understand the desired behavior is to test out your facebook feed and shrink your screen height so that your viewport is smaller than your sidebar height. I'll try to summarize here:
When your viewport is taller than your sidebar (simple case)
The sidebar behaves exactly as you'd expect with position: sticky. The sidebar stays in the same place and follows as you scroll down and up.
When your viewport is smaller than your sidebar
When you scroll down initially the sidebar scrolls with the feed (they appear fixed together)
When you get to the bottom of your sidebar, it then locks at the bottom and as you scroll down more, the sidebar now appears sticky with the bottom fixed
When you now scroll back up, the sidebar once again appears attached to your main feed, and scrolls up with the main feed. Once you hit the top of the sidebar it's then sticky with the top fixed.
So between those two states (top fixed when scrolling up, bottom fixed when scrolling down), the sidebar scrolls in unison with the main feed.
It's a very nice scrolling experience but very hard to recreate.
I have accomplished the states listed in steps 1-3 above by applying position sticky with a top position, and when you scroll down, using scroll events and some viewport/sidebar height calculations to determine the height difference and adjusting the top css value so it locks when the bottom is lined up with the screen (essentially initialTop - (sidebarHeight - viewportHeight). I cannot figure out steps 4, and 5. The best I could do was transition between the two top values depending on your scroll direction but it's a very bad UX.
I have a sandbox example of a layout here: https://codesandbox.io/s/fragrant-microservice-89b7z?fontsize=14&hidenavigation=1&theme=dark
There's a basic layout with 2 columns (left sidebar and main feed). And there's a react component called StickyScroll which wraps around the column and has all the logic to update the top value. This may be a completely wrong start to a good solution, but any help is greatly appreciated.
I was interested in this as well, so I spent some time studying how fb does it.
It's very clever, my hat off to whichever fb dev originally implemented this.
You have to set the top / bottom css properties on the sticky depending on the direction of scroll, and to keep things from jumping around, you also have to calculate the height of an the element above the sticky, based on scrollTop.
Here is a rough example, which demonstrates the logic in action
I try to make a mock up by your sandbox code based on facebook redesign 2020.
hope you find the answer here. I like this approach because it's not very complex. More precisely, I use the css solution when I have to create a component similar to the Facebook sidebar.So i'm not using your StickyScroll component. Hope you find something.

Responsive content wrap when using position absolute footer

Working on a new design using bootstrap3 and trying to stretch the page so that even if there's not enough content to fill the page, the footer section would stay to the bottom.
The reason why I'm using position absolute, is because there's a link from the billing software that's being added within the content, I don't want to remove the link but position it a bit to the bottom in the footer section, in the center bottom, thus since I can't control where this will appear(do know where appears, just can't control), using position absolute on the specific element helps me here.
Now, that's not issue, just saying why I need to use position absolute and why I made the divs like this:
wrapper
>>wrapper_content
>>wrapper_footer
fiddle: http://jsfiddle.net/raicabogdan/jsk1b7ua/4/
the footer section is properly set to the bottom, however for some reason, the wrapper_content does not go 100% height automatically on load or on window resize. Also if you resize to mobile view, content will go down few table rows.
The content goes under the footer section.
What am I doing wrong here? Left a fiddle of the html page along with some css that I felt were needed above.
Hope there's someone that could get me out of this.
Cheers.
Try this link. I have used this method to get the footer to stay at the bottom of the window.

Two content area scrollable by browser's vertical and horizontal scrollbars

Is it possible to design page like on this picture:
I need reach only three goals:
First content can be scrolled only vertically.
Second content can be scrolled only horizontally.
Must be used only browsers scrollbars.
p.s. Better if we will not use javascript code.
Yes, this is possible.
The real difficulty is to add scrollbars outside de views.
But when done, you can easily scroll to a position your scrollviews.
I don't think this is really a good feature to make this but why not.
Be strong!

How do I center something with CSS so that it is centered relative to the scroll bar?

I have centered a div on a page for a group project and while the div itself is centered, the websites contents are centered with the scroll bar in mind. What I mean by this is that the web page contents are centered so that the width of the screen is measured without the scroll bars width. So if the monitor was originally 100px wide, it gets read as 100-(scroll bar width) px wide. Unfortunately, this has caused my fixed position div to be a scroll bars width off center from the rest of the site and it looks pretty funky. Any way to fix that? Can't use jquery, can potentially use a little bit of JS.
Here's the link to my site so you can see what I'm talking about. http://51713941.nhd.weebly.com/index.html
Lets see some code.
This can normally be sorted out with css. Margin:auto
You should use the box model concept in css to style and place the content on the site
Again, the question seems rather vague.

Sticky footer with adjustable height

I'm trying to have a sticky footer on my page but with a twist compared to what I've seen before.
The top of the footer as to always be sticky at 50px after the content and a green color as to fill the rest of the footer until the end of the page.
You can see an example on http://enviro2012.tapagecommunication.com
The problem is even better illustrate if you clicl on the "send" button in the Facebook plugin at the bottom of the page.
Let me know if you need more info! :)
Thanks!
I've had this one before. I tried all sorts of methods, including checking the window height against the vertical position of the footer, then setting the footer height to the difference. It didn't work too badly across most browsers.
However, the most simple (and fast-rendering) solution was to add enough bottom padding to the footer to cover the gap on most window sizes. Assuming your content is always going to fill the majority of the page, a few hundred pixels should be more than enough – and renders properly the first time the page loads.
