How do I make the header and side-bar fixed? - javascript

I am following MVC approach where you can keep some contents static .i.e. header , footer , sidebar etc using layout.In my view, i want to make header and side-bar fixed while user scroll-down the page. Any help ?

Use position : fixed for your header div and sidebar div.

You could definitely cleanup the sidebar and fixed positioning, but this demo seems to work (quick mockup only). You'd need to add the CSS to your stylesheet, and then create partials for the header, sidebar and main content window.
In the CSS (below), you'd need to adjust some properties to make sure everything aligns properly as you're setting up your design.
* { box-sizing: border-box; }
.header {
position: fixed;
top: 0;
left: 0;
width: 100%;
padding:10px;
background-color: #eee;
border-bottom: 1px solid #ddd;
}
.container { padding-top: 32px; } /* Adjust this value based on height of .header */
.main {
width: 70%;
margin-left: 30%;
padding-left: 20px;
}
.sidebar {
position: fixed;
top: 41px; /* Adjust this value based on height of .header and any additional padding */
bottom: 0;
width: 30%;
overflow-y: scroll;
}

Can't click on browser vertical scrollbar because of a fullscreen fixed bootstrap modal

I am using Bootstrap 4 on my project, and modified the modal style in order to make it fullscreen like you can see it on this css code:
.modal.show {
display:flex!important;
flex-direction:column;
justify-content:center;
align-content:center;
align-items: flex-start;
}
.modal-body {
padding: 0;
margin: 0;
}
.close {
color: #aaa;
position: absolute;
/* background: blue !important; */
border: 0;
top: 0;
z-index: 99999;
right: 3%;
float: none;
opacity: 1;
font-size: 40px;
font-weight: 400;
}
.modal-backdrop.modal-backdrop-transparent {
background: #ffffff;
}
.modal-backdrop.modal-backdrop-transparent.in {
opacity: .9;
filter: alpha(opacity=90);
}
.modal-backdrop.modal-backdrop-fullscreen {
background: #ffffff;
}
.modal-backdrop.modal-backdrop-fullscreen.in {
opacity: .97;
filter: alpha(opacity=97);
}
.modal-fullscreen {
background: #fff;
min-width: 100%;
margin: 0;
}
#media (min-width: 768px) {
.modal-fullscreen .modal-dialog {
width: 750px;
}
}
#media (min-width: 992px) {
.modal-fullscreen .modal-dialog {
width: 970px;
}
}
#media (min-width: 1200px) {
.modal-fullscreen .modal-dialog {
width: 100%;
}
}
.modal-dialog {
position:fixed;
padding: 0;
max-width: 100%;
margin: 0;
top: 0;
bottom: 0;
left: 0;
right: 0;
height: 100vh;
overflow:auto;
}
When I tried to scroll down the vertical scrollbar of the browser, it won't ! I can use mouse scroll wheel but not by clicking on it directly !
Are you able to detect the problem ? It's for sure the fixed position but it is needed to make it fullscreen.
Here a jsfiddle to see a live demo of the problem:
https://jsfiddle.net/odbjcpt2/1/
I don't want to use position FLEX instead of FIXED since it won't solve the problem on my project, even if in the example given it will works (modal keep ading padding-right to body ... it is fixed using FIXED).
Thank you
In your JSFiddle, the problem appears to be with the div that contains the Lorem Ipsum text. It has pointer-events: auto; inherited from .modal-content class and if you remove that it ends up with pointer-events: none; inherited from modal-dialog class. If you take both those away, the problem goes away.
EDIT
I believe the root of the issue is that you're setting your .modal-dialog class to have fixed position and overflow auto.
Below is from bootstrap doc
Modals use position: fixed, which can sometimes be a bit particular
about its rendering. Whenever possible, place your modal HTML in a
top-level position to avoid potential interference from other
elements. You’ll likely run into issues when nesting a .modal within
another fixed element.
After playing around, if I edit your CSS in your JSFiddle example and in the .modal-dialog class I just remove position:fixed; and overflow:auto;, the problem goes away.
EDIT AGAIN
I just noticed you actually have .modal-dialog defined in your CSS twice, the first time with flex position and second time with fixed. Sounds like that was maybe a copy/paste mistake. Anyhow, still the same root cause I think, because your .modal-dialog div is fixed and it's inside your .modal div, and bootstrap doc says don't put another fixed inside a .modal

Add scrolling to Lightbox2

Heres an image of the issue I'm trying to resolve. I am working on my portfolio site; and I have images of some of my personal projects, all of them are the same width but some have different heights. Due to getting full page screenshots of my work, some of the images have a much greater height than others. Instead of allowing displaying all the images the same size and allowing scrolling in the modal window, it scales the images down to fit within the same height as all the others. This gives it an odd look cause some of the images get scaled down a lot. I would like to get all the images to display in the same width, and those that need it to allow scrolling to see the rest of the image. I tried to use overflow: scroll; on the .lightbox but that didn't help. I've also tried overflow-y. I would also like to disable the page in the background from being able to scroll, to allow the scrolling to be focused on the images that it is necessary on.
.lightbox {
position: absolute;
left: 0;
width: 100%;
z-index: 10000;
text-align: center;
line-height: 0;
font-weight: normal;
}
.lightbox .lb-image {
display: block;
min-width: 100%;
height: auto;
border-radius: 3px;
/* Image border */
border: 4px solid white;
}
.lightbox a img {
border: none;
}
.lb-outerContainer {
position: relative;
*zoom: 1;
width: 250px;
min-height: 250px;
margin: 0 auto;
border-radius: 4px;
/* Background color behind image.
This is visible during transitions. */
background-color: white;
}
Lightbox2 by default appends calculated width & height to the image and .lb-outerContainer. But you can override this by doing the following -
.lb-outerContainer {
width: 100% !important;
height: auto !important;
}
.lightbox .lb-image {
width: 100% !important;
height: auto !important;
}
I don't recommend this because this breaks the intended use of this plugin. I'm sure you'll find an alternative to lightbox2 that achieves what you're looking for. So you can consider this as a temporary fix.
EDIT: Here's a jsfiddle to see it work. https://jsfiddle.net/hsugx6wm/43/

How to put my footer always on the bottom of my page? [duplicate]

This question already has answers here:
How do you get the footer to stay at the bottom of a Web page?
(32 answers)
Closed 6 years ago.
How can I have a footer which always stays at the bottom of my page even if this page is too little to fill the entire screen or more ?
I have a button in my page, and when you touch it, it adds thanks to javascript many elements to my page and the page size changed, but my footer doesn't adapt its position.
The problem is when I set the position of my footer to relative, when my page size is too short, he is not at the bottom of my screen, but just under the last element I put on.
I tried position: absolute;, but when the user clicks on the button, my footer stays stuck at his position and it doesn't go to the new bottom of my page.
I don't want my footer to be always visible, but just to be at the real bottom of my page.
Use this:
footer {
position: fixed;
bottom: 0;
/* Add a height and a width! */
}
The complete solution is explained in this article: http://matthewjamestaylor.com/blog/keeping-footers-at-the-bottom-of-the-page
Major trick is, that you will have three parts: Header, Body and Footer:
HTML:
<div id="container">
<div id="header"></div>
<div id="body"></div>
<div id="footer"></div>
</div>
CSS:
html,
body {
margin: 0;
padding: 0;
height: 100%;
}
#container {
min-height: 100%;
position: relative;
}
#header {
background: #ff0;
padding: 10px;
}
#body {
padding: 10px;
padding-bottom: 60px; /* Height of the footer */
}
#footer {
position: absolute;
bottom: 0;
width: 100%;
height: 60px; /* Height of the footer */
background: #6cf;
}
Use the following
footer {
position: absolute;
bottom: 0;
}
try this one... this will keep your footer at the bottom of your page:
position: fixed;
bottom: 0;
Working demo: https://jsfiddle.net/maky/bgeLbpd9/
#footer {
position: fixed;
bottom: 0;
background-color: black;
min-width: 100%;
font-family: Agency FB;
transition: height 3s;
height: 50px;
}
#footer1 {
text-align: center;
color: #4e4e4e;
}
#footer:hover {
opacity: .8;
color: white;
height: 100px;
}

Expand the element's height to bottom of the page

I have a canvas in my page, and i want it to fill the page until it reaches the bottom of the page.
I have the canvas' width set to 100%, but i cannot set the height to 100% as it extends too far.
The position of the div is not 0,0 of the browser window there are other things above it, so i end up with a scroll bar because 100% height extends well below the bottom of my browser's output.
So i was wondering how can i extend the element's height to reach the bottom of the page from its current position on the web page?
<style>
.canvas{
position:absolute;
width:100%;
height:100%;
}
<style>
<div class="logo">Stuff here</div>
<div class="output">
<canvas class="canvas"></canvas>
</div>
Do i need to use JavaScript or is there a CSS method to doing this?
If you know the height of the content above the canvas, you can use top and bottom properties to take up the rest of the space:
JS Fiddle
.logo {
height: 40px;
}
.output {
position: absolute;
top: 40px; // height of above content
bottom: 0;
width: 100%;
padding: 0;
}
.canvas {
position: absolute;
width: 100%;
height: 100%;
padding: 0;
margin: 0;
}
And if you don't know the height of the above content, you can calculate it:
JQuery Example: JS Fiddle
var height = $('header').height();
$('.output').css('top', height);
this technique is also great when making resizable popups with fixed height headers and footers, but fluid height content
https://jsfiddle.net/ca5tda6e/
set the header (.logo) to a fixed height
.logo{
height: 100px;
background-color: lightGray;
position: relative;
z-index: 1;
}
then position the content (.output) absolute, with a padding-top: 100px
.output{
width: 100%;
height: 100%;
box-sizing: border-box; /* so that padding is included in width/height */
padding-top: 100px; /* padding-top should be equal to .logo height */
position: absolute;
top: 0;
left: 0;
overflow: hidden; /* there was like a pixel of something i couldnt get rid of, could have been white space */
}
I've had this problem before, in CSS, create this rule....
html, body {
margin: 0;
}

CSS - displaying a dynamic height floated DIV - missing background image

My Goal:
Here is what I'm trying to accomplish. We have an list of categories that appear on a page. The number of categories is unknown. The description can be pretty much any size... yet we want a uniform look. So, we are using the dotdotdot plugin to put ellipses on the paragraphs. When you hover over the item, it should expand the description and show the full text.
I want that hover to float or overlay whatever is below it. Due to some of my layout items (see my NOTE below) my sccontainer element doesn't have a set height. It's dynamic based on the content... with a max-height set.
When I change that height to AUTO in the hover event (which causes the text to flow down and displays all the content), I lose the background on the sccontainer element.
Some pertinent CSS:
.sccontainer { width: 280px; zoom: 1; float: left; margin: 5px 10px; padding: 0; border: 1px solid #8697a1; -moz-border-radius: 5px; border-radius: 5px; -moz-box-shadow: 0 0 6px #777; -webkit-box-shadow: 0 0 6px #777; box-shadow: 0 0 6px #777; -ms-filter: "progid:DXImageTransform.Microsoft.Shadow(Strength=6, Direction=90, Color='#777777')"; filter: progid:DXImageTransform.Microsoft.Shadow(Strength=6, Direction=90, Color='#777777'); position: relative; background: #fff url(http://imagecss.com/images/background.jpg) repeat-x left top; }
.sccontainer .parent { position: absolute; width: 270px; }
.sccontainer .image { margin: 5px; float: left; }
.sccontainer .image img { width: 48px; }
.sccontainer .icon { margin: 0; }
.sccontainer p { margin: 8px; padding: 0; max-height: 145px; }
.sccontainer h1 { line-height: 24px; display: inline-block; vertical-align: middle; width: 200px; height: 48px; padding: 0; margin: 5px 0 0 0; overflow: hidden; }
.sccontainer h1 a { padding: 0; font-size: 24px; color: #fff; font-weight: normal; }
.sccontainer .content { position: relative; height: 210px; padding: 0 5px; font-size: 15px; line-height: 22px; width: 270px; }
.sccontainer a:hover { text-decoration: underline; }
.sccontainer.hover { height: 250px; }
.sccontainer.hover .content { height: auto; }
.sccontainer.hover .content p { min-height: 135px; max-height: none; }
jsFiddle:
Here is a jsFiddle version of what I have right now. You can see this in action, if you hover over the text in the blue box. It's a bit large, so I used jsFiddle instead of putting all the bits here code tags...
http://jsfiddle.net/ztMM5/1/
And here is a mockup of what I'd like to see. Method 5a expands slightly to show the full content.... yets overlaps the red line. None of the other items move around or are affected.
NOTE: Sorry for the size of things. I've trimmed it down about as much as I can. Also, I am modifying an existing intranet website... it's 3rd party, so I have limited control of the source code - hence the table usage. :(
What I've Tried/Researched:
I believe the issue stems from the fact that my sccontainer item is floating, and doesn't have a height specified. That's why the image disappears.
I had a version that kept the background... but the sccontainer box didn't resize like we need... the text just overflowed it... rather ugly.
I don't know enough CSS to make this all work right. I'm not adverse to using jQuery to do more if needed.
I did work on a version that handled most of the hover using the :hover stuff... but it didn't work quite as well as the jQuery approach.
This answer may not solve your specific problem but it may help others with a similar scenario (working with tables makes difficult to render a clean layout in most cases.)
I ran into this issue before and this is how I solved it. It basically relies in an html nested div structure to achieve the expandability of the content without affecting the floating layout of the near elements :
<div id="wrapper" class="cf"><!--wrapper with border and CLEARED-->
<div class="sccontainer"><!--position relative-->
<div class="inner"><!--position absolute-->
<div class="content"><!--position relative-->
<!-- my content here -->
</div>
</div>
</div>
<!-- more containers etc-->
</div><!--END wrapper-->
First, we are going to apply the infamous clear-fix hack to the #wrapper container (use your preferred method):
.cf:after {
visibility:hidden;
display:block;
content:"";
clear:both;
height:0
}
* html .cf {
zoom:1
}
/* IE6 */
*:first-child+html .cf {
zoom:1
}
Then the style for the .sccontainer container :
.sccontainer {
width: 280px; /* or whatever - could be % for responsiveness */
padding-bottom:200px; /* any value to give height without using height ;) */
position: relative;
float: left;
margin: 5px 10px; /* or whatever */
overflow: hidden; /* this is important to keep all same height and big content out of sight */
z-index: 1; /* this is important too, see later */
background: white url("imagebackground.jpg") 0 0 repeat-x; /* need to explain? */
}
Then the .inner container, which actually will help to keep the layout in order if we hover the elements
.inner {
position: absolute; /* please don't move */
width: 100%; /* to fill the whole parent container */
height: 100%; /* same */
}
And the content :
.content {
position: relative;
background: white url("imagebackground.jpg") 0 0 repeat-x; /* not redundant though */
width: 100%; /* helps to fill the gaps with small content */
height: 100%; /* same, specially if using image backgrounds */
/* other styles, etc */
}
NOTE: we should apply same border-radius properties to the three containers and box-shadow to .sccontainer and .content for consistency
Now, what happens when we hover ?
.sccontainer:hover {
overflow: visible; /* show the full content */
z-index: 999; /* place me on top of the others if needed (which lower z-index, remember?) */
}
.sccontainer:hover .content {
height: auto; /* as it really is, including background image */
}
NOTES : this effect will happen regardless if the content's height is smaller than the parent container's height. You may not like the effect mostly if you are using borders and shadows (could be shown as smaller box inside the parent container) so we could add an extra class to .sccontainer like
<div class="sccontainer withhover">
and apply the hover effects only if that class exist like
.sccontainer.withhover:hover {
overflow: visible;
z-index: 999;
}
... and use a bit of jQuery to remove that class for shorter content, so it won't be affected :
jQuery(document).ready(function ($) {
$(".sccontainer").hover(function () {
var $contentHeight = $(this).find(".content").height();
if ($(this).innerHeight() > $contentHeight) {
$(this).removeClass("withhover");
}
});
});
