I am creating an image effect where the text at the bottom of a paragraph fades away
This is the effect I'm trying to achieve:
I have some working HTML & CSS which achieves this look but I am looking to see if there is a better way to achieve this effect? I've often found that there are HTML tricks to do what I want that I dont know of.
I'm open to using JQuery if it has the ability to do this effect but a native HTML CSS effect would be best. Plus is my solution cross browser?

You can achieve this with Cufon, a legal way to embed [almost] any font into a webpage through Javascript. You'd just include the Cufon API as usual, and your Javascript code would look like this:
Cufon.replace('.paragraph', { color: '-linear-gradient(black, blue)' });
What this does is select the element with class "paragraph" (CSS selectors can only be used if you have a library that supports it on your webpage too, like jQuery and sets its color to a linear gradient. In this case I made it go from black to blue so that by the end it blends in with your background color (according to the image you showed us, that is).
I'll get a live demo up soon.
Fair warning though, text fading into the background is not exactly user friendly. It's up to you whether you'd like to continue using it. I do admit it's a nice effect, but only when it's still perfectly legible.
Try something like this. Basically we use CSS gradients and opacity to set the color.

You can use a site like this one to help with getting the css written. Basically what you do is absolutely position a div at end of paragraph of fixed height. We apply a gradient opacity change to it.
div.fade {
position: absolute;
bottom: 0;
height: 45px;
width: 100%;
background: -moz-linear-gradient(top, rgba(125,185,232,0) 0%, rgba(30,87,153,1) 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(125,185,232,0)), color-stop(100%,rgba(30,87,153,1))); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top, rgba(125,185,232,0) 0%,rgba(30,87,153,1) 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top, rgba(125,185,232,0) 0%,rgba(30,87,153,1) 100%); /* Opera 11.10+ */
background: -ms-linear-gradient(top, rgba(125,185,232,0) 0%,rgba(30,87,153,1) 100%); /* IE10+ */
background: linear-gradient(top, rgba(125,185,232,0) 0%,rgba(30,87,153,1) 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#007db9e8', endColorstr='#1e5799',GradientType=0 ); /* IE6-9 */

I have a fixed navbar and the site's background changes with sections (the sections background is diagonal). Now I want the background color of the navbar to change with the background of the underlying section's background color, without just setting the navbar's background color to the same color but the navbar to be transparent to the background but not it's content, like this:
example of how it should like
and not like that:
example of how it should NOT look like
I'm super thankful for any idea or approach on how to achieve something!
If you want to keep the navbar on top all the time, change position to fixed and change set z-index to a high value so it is on top of all other elements, you may use the following CSS class for navbar. Of course, you can set the background-color and opacity to the values that match your background.
.myNavBar {
position: fixed;
width: 100%;
top: 0;
left: 0;
z-index: 1000;
}
Without sharing some codes on how you are achieving the undesired results it might be hard to help you out.
Try this and it would work, I guess.
Within the container for the navbar, set the z-index in the CSS to a very high number, say 1999. This would make sure the navbar remains on top of other elements, assuming no other element has been set to have a z-index greater than 1999, in this case.
.navbar-container {
z-index: 1999;
}
Fading Content using Iframes (No JavaScript)
You will need to create an Iframe tag with the src attribute set to the content file you want to fade. The main content has to have separate styles. The iframe must be in focus to allow scrolling. More details are in the code below.
Demo: https://fadingiframe.netlify.app/
/* Index.html style style-sheet below */
iframe {
position: absolute;
top: 5rem;
width: 100vw;
height: calc(100vh - 6rem);
border: none;
-webkit-mask-image: linear-gradient( /* Mask iframe */
transparent 1rem,
#fff 5%,
#fff 70%,
transparent 90%
);
mask-image: linear-gradient(
transparent 1rem,
#fff 5%,
#fff 70%,
transparent 90%
);
}
/* mainContent.html style style-sheet below */
body {
position: absolute;
overflow-x: hidden;
margin-top: 2rem;
color: aliceblue;
width: 80vw;
left: 5vw;
}
body::-webkit-scrollbar { /* Remove scroll bar */
display: none;
}
body {
-ms-overflow-style: none; /* keep in mind that it will only scroll if the iframe is in focus */
scrollbar-width: none;
}
p {
padding: 2rem;
font-size: 2rem;
}
<body>
<nav></nav>
<iframe id="main-content-iframe" src="mainContent.html"></iframe>
<!-- Add iframe and src to main content html file -->
<canvas id="canvas1"></canvas>
<footer></footer>
</body>
<!-- Separate html file in root directory -->
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
<link rel="stylesheet" href="./mainContent.css" /> <!-- Link to css file -->
</head>
<body>
<section>
<!-- Your Content here-->
</section>
</body>
</html>
-------------------------------------------------------------------------
For Text only -
Body Tag Has Special/Hide Properties
I think your issue is that you do not use the "body" element selector. It has unique properties that set the body element height to match the screen by default. Although it still allows scrolling the inner content. I add an extra background div for the text as well. It provides a better reading experience. Please have a look at my solution. It may help you solve your problem. If you have any questions, don't hesitate to ask.

-webkit-background-size: cover;
background-size: cover;

background-image: Linear-gradient(

);

How can I generate in realtime this outline effect similar to this image using css3 or javascript?
http://i.imgur.com/1OEnuKF.jpg
Here is an similar effect achieved with filter and background-blending
div {
width: 180px;
height: 400px;
display: inline-block;
}
.test {
background: url(http://i.imgur.com/1OEnuKF.jpg), url(http://i.imgur.com/1OEnuKF.jpg);
background-position: 0px 0px, 3px 3px;
background-size: cover;
background-blend-mode: difference;
-webkit-filter: blur(1px)invert(1);
}
.target {
background: url(http://i.imgur.com/1OEnuKF.jpg);
background-position: top right;
background-size: cover;
}
<div class="test"></div>
<div class="target"></div>
The left part of the image is achieved from the original image; the right hand is the target image.
there are some filter effects in CSS3 , only for webkit
I've no idea how to use them to make the effect you showed
but I think they can help
here is a link that you can test CSS3 filters and get the css code
http://html5-demos.appspot.com/static/css/filters/index.html
and here you can see it's Browser compatibility
hope that help's
I´ve got a CSS problem with a input-range element:
<input type="range" id="difficultSelect" max="3" min="1" value="2"/>
the css looks like this:
-webkit-appearance: none;
z-index: 102;
width: 225px;
height: 5px;
margin-left: 95px;
margin-top: 15px;
border-radius: 2px;
background: linear-gradient(to right, #83f922 0%,#ff4c00 100%);
background: -webkit-gradient(linear, left top, right top, color-stop(0%,#83f922),
color-stop(100%,#ff4c00));
background: -moz-linear-gradient(left, #83f922 0%, #ff4c00 100%);
background: -webkit-linear-gradient(left, #83f922 0%,#ff4c00 100%);
As u can see, the background of the slider should show a linear-gradient from green to red.
In Chrome it displays as intended, but in Firefox there is the background-gradient, but ontop of it is the normal "grey" bar of the slider: http://imgur.com/xcxuZXV
Were is my mistake? Firefox Version ist 27.0.1
THANKS
Mozilla has a separate property to style the shadow dom of the input (which is what -webkit-appearance:none; takes care of for webkit):
::-moz-range-track {background:transparent; border:0px;}
On a side note, you can also style the slide/grip/button/thumb:
/* These need to be separated, not combined with a comma */
::-webkit-slider-thumb { /* ... */}
::-moz-range-thumb { /* ... */}
Please look at this page
What I want to achieve is
and
Using following jQ function to dynamically resize div height based on document height
$(window).load(function() {
$('.sideBg').css({ 'height': ($(document).height())});
});
What am I missing?
Wouldn't it be better if you just used the background on the body? This way, you don't even need the additional elements or JavaScript.
body {
background: url(http://vefaestetik.az/design/img/bg/side_bg.png),
url(http://vefaestetik.az/design/img/bg/side_bg.png) 100% 0,
black radial-gradient(ellipse at center, #45484D 0%,black 100%);
background-repeat: repeat-y;
}
Don't forget to use background: black url(/design/img/bg/000.png); for the footer.
And don't forget that you should also have the prefixed versions
background: url(http://vefaestetik.az/design/img/bg/side_bg.png),
url(http://vefaestetik.az/design/img/bg/side_bg.png) 100% 0,
black -webkit-radial-gradient(center, ellipse cover, #45484D 0%,black 100%);
background: url(http://vefaestetik.az/design/img/bg/side_bg.png),
url(http://vefaestetik.az/design/img/bg/side_bg.png) 100% 0,
black -moz-radial-gradient(center, ellipse cover, #45484D 0%,black 100%);
background: url(http://vefaestetik.az/design/img/bg/side_bg.png),
url(http://vefaestetik.az/design/img/bg/side_bg.png) 100% 0,
black -o-radial-gradient(center, ellipse cover, #45484D 0%,black 100%);
before the unprefixed one in the styles for the body.
Works for me if I make these changes via Developer Tools
About compatibility: multiple backgrounds have better support than gradients (multiple backgrounds are supported by IE9, while CSS gradients are not). Actually, this won't work in IE 9 precisely because of the gradient. However, you can make it work in IE9 without the gradient by adding before all the prefixed versions a multiple background fallback (without the gradient).
background: url(http://vefaestetik.az/design/img/bg/side_bg.png),
black url(http://vefaestetik.az/design/img/bg/side_bg.png) 100% 0;
you need to remove the margin-top that is on your .wrapper <div> for the top to be fixed:
.wrapper {
background: url("/design/img/wrapper-bg.png") no-repeat center top;
margin-bottom: 0 !important;
margin-left: auto;
margin-right: auto;
/*margin-top: 20px; remove this */
padding-top: 120px;
position: relative;
width: 1020px;
}
Then for the bottom part i would suggest to get the height of the .wrapper <div>:
$(function() {
var wrapperHeight = $('.wrapper').height();
$('.sideBg').css('height': +wrapperHeight+'px');
});
If you are facing unnecessary padding always use a reset.css file.

Can I do something like this with pure html and if needed css and javascript:
And when the mouse focuses, it becomes like this:
So I was thinking of an image placeholder. Am I on the right track, or is there a better/more simpler or more straightforward method?
EDIT: Just out of pure curiosity, how would I accomplish this using JavaScript, as all the current answers are all CSS-related?
From my knowledge this is simply CSS background image.
http://www.w3schools.com/cssref/pr_background-image.asp
Have it look there, you can accomplish this by setting its position like here: http://www.w3schools.com/cssref/pr_background-position.asp
You can also change the background image depend on if the item is focused or not simply showing the back ground image when focused and hiding it when its not like:
#item:focus{
bacground image code here
}
More details on focus here: http://www.w3schools.com/cssref/sel_focus.asp
And some focus usage example: http://www.mozilla.org/access/keyboard/snav/css_usage.html
UPDATE WITH RESOURCE - THANKS #MrMisterMan
http://developer.mozilla.org/en/CSS/background-image
http://developer.mozilla.org/en/CSS/background-position
JAVASCRIPT:
Using JavaScript add the attribute to your element like below:
This will call your function when it has focus and pass it the input element.
Also you can detect onfocusout
Hope this helps, any questions just ask :)
If you only need to support the latest Browser use this:
HTML:
<input placeholder="Google Custom Search" type="search" name="q">
CSS:
#myInput::-webkit-input-placeholder {
color: transparent;
text-indent: -9999px;
background-image: url("http://placehold.it/150x20");
background-position: 0 50%;
background-repeat: no-repeat;
}
#myInput::-moz-placeholder {
/* Firefox 19+ */
color: transparent;
text-indent: -9999px;
background-image: url("http://placehold.it/150x20");
background-position: 0 50%;
background-repeat: no-repeat;
}
#myInput:-moz-placeholder {
/* Firefox 18- */
color: transparent;
text-indent: -9999px;
background-image: url("http://placehold.it/150x20");
background-position: 0 50%;
background-repeat: no-repeat;
}
#myInput:-ms-input-placeholder {
/* IE 10- */
color: transparent;
text-indent: -9999px;
background-image: url("http://placehold.it/150x20");
background-position: 0 50%;
background-repeat: no-repeat;
}
JSFiddle
Browser Support
If you need an image (google logo in the question) you should set the placeholder image as the background of the text field:
input.search {
background-image: url("placeholder.gif");
background-repeat: no-repeat;
}
input.search:focus {
background-image: none;
}
Note: :focus is a pseudo-class in css, which is activated on focus
You may use just CSS.
You can give a solid border with say 4px width.
You can make round corners foor your input using moz-border or webkit-border radius.
You can use a border background image.
here you can read about css3 borders http://www.w3schools.com/css3/css3_borders.asp
You may try
input {
border:2px solid #dadada;
border-radius:7px;
font-size:20px;
padding:5px;
}
input:focus {
outline:none;
border-color:#9ecaed;
box-shadow:0 0 10px #9ecaed;
}
