I have a div that will be the header of the site I'm working on that is a custom shape. The issue I am having is that the header needs to resize horizontally while retaining the integrity of the border radius and curves that are part of the shape. The problem with just using a transparent div with the shape as a background SVG is that when the window is resized, the integrity of the border radius and the angled section of the graphic are lost, meaning they get distorted into another shape. Here is an image of the shape:
The initial way I attempted to create this element was by placing it as an SVG, and resizing one of the line segments of the SVG in Javascript, but the performance on this was very poor, it was overly-complicated, and it was difficult to get the sizing correct.
The closest I got to the desired result was by cutting the right side tail of the SVG and using it as an :after element, which gave me the horizontal fluidity I was looking for, but encountered issues with matching the border color of the div and the stroke of the SVG. The div uses a translucent white background and a translucent colored border. Since the border is technically "on top" of the white background, the resulting color value is dynamic depending on the background of the page. This makes it difficult to match the stroke of the SVG and the border color of the div. There was also an issue where a vertical line would show up at different resolutions between the div and :after SVG element. You can see in the picture below that this method is not ideal, the SVG border color and width does not match the div on the left, and if you look closely there is a gap between the two elements (much more visible on a dark background which the site will be using).

You were on the right track with splitting up the image. You could either split the png you provided in your example, or if you have access to the tools, you could make three svgs.
Using the png you provided as an example, I made a new image 50px wide starting from the left. I made a second image 500px wide starting from the right. Finally, for the center, I made a third image that was only 1px wide taken from the horizontal center of the provided png. That 1px can be repeated horizontally to give the illusion that it is one image.
There are many ways to assemble them for the header. You could use a table, a grid, divs with positioning and float. I chose to use flex.
body {
background-color: black;
margin: 10px 20px;
}
.header {
display: flex;
flex-direction: row;
flex-wrap: nowrap;
height: 96px;
}
.header_left {
flex-grow: 0;
background-image: url("h_left.png");
background-repeat: no-repeat;
width: 50px;
max-width: 50px;
min-width: 50px;
}
.header_middle {
flex-grow: 1;
display: block;
background-image: url("h_mid.png");
background-repeat: repeat-x;
}
.header_right {
flex-grow: 0;
display: block;
background-image: url("h_right.png");
background-repeat: no-repeat;
width: 500px;
max-width: 500px;
min-width: 500px;
}

I'm trying to make a puzzle out of a background image with numbered pieces. The pieces will eventually be movable with javascript. Right now, I'm stuck simply trying to position the pieces of this image. The html has a div with id called puzzlearea, and I have appended children with javascript, which I know works because it displays the new div pieces and their numbers. The CSS refuses to move the pieces relative to this background, and my two test pieces are stuck in the top left corner, seemingly ignoring my background-position values. Here is the CSS:
body {
text-align: center;
font-family: cursive;
font-size: 14pt;
}
#puzzlearea {
width: 400px;
height: 400px;
margin: auto;
position: relative;
background-image: url("planck-image.png");
}
.tile {
font-size: 40pt;
color: red;
line-height: 70pt;
width: 90px;
height: 90px;
border: 5px solid black;
background-position: -200px -200px;
position: fixed;
}
Update: Screenshot.
Would you have any ideas as to why the positioning is not occurring?
You need position: absolute on .tilein order to be able to place them with the top/bottom/left/right parameters (and you need those too).
fixed position refers to the viewport, not the parent element.
I'm trying to insert an vertical image 1 pixel wide into my webpage but depending on the browser, zoom level or position of other elements on the page the image is often resized to be 0 pixels and dissapears. How can I stop this? Am I doing this wrong?
My html image (green space is just 1 pixel of green.
<IMG class="dividerImage dday3" SRC="/SafeSiteLive/images/safesite_documents/icons/greenspace.gif">
My css
.dividerImage {
float: left;
margin-top: 50px;
height: 50vh;
width: 1px;
}
Some green vertical images not displaying
Different zoom level more of the images display
I should have been using an empty div instead, works much better.
<div class="dividingDiv">
</div>
And the css.
.dividingDiv {
border-left: 1px solid green;
float: left;
height: 50vh;
margin-top: 50px;
width: 0;
}
On a website there is a black line on the left of a picture about 1 or 2 pixels long. I can't get rid of it after checking the code (border etc). I think its a javascript problem. The picture doesn't have the black line on the home page but does have it on subsequent pages. There is no margin etc. How would I identify/fix the problem
image with no black border

image with black border on left hand side

Check out your css and remove the background image.
Actually the float: left is causing the issue, so you can remove it afaik
#tourDetFluidOuter {
margin: 0;
padding: 0 0;
width: 100%;
height: 100%;
float: left;
background: url(/images/tour-detail-bg.gif) repeat-x 0 0;
}
this black border (actually it is not a border but a background) is produced by
#tourDetFluidOuter {
margin: 0;
padding: 0 0;
width: 100%;
height: 100%;
float: left;
background: url(/images/tour-detail-bg.gif) repeat-x 0 0;
}
just remove the background or cover it fully.
Ok so I have a divider image that has the top and bottom parts fading like so:
Can I use a sprite and 3 DIV's for repeating only the middle part of it? I have to mention that my height is variable. How can I do something like that? Do I need 3 images (top, middle and bottom) ?
Current HTML & CSS code for this:
HTML:
<div class="left-side">
</div>
<div class="vdiv25p"></div>
<div class="right-side"></div>
CSS:
.left-side {
display: inline-block;
width: 720px;
}
.vdiv25p {
display: inline-block;
width: 24px;
height: 658px;
background-image: url(../images/vdiv-large.png);
background-position: center center;
background-repeat: no-repeat;
}
.right-side {
width: 236px;
display: inline-block;
vertical-align: top;
}
P.S. I know how to do it with JavaScript or jQuery but I was wondering if there was a CSS-only solution :)
I think i understand what you are asking for now. Please correct me if i am misunderstanding.
http://jsfiddle.net/6fowh58o/
.vdiv25p {
display: inline-block;
width: 24px;
height: 658px;
background-image: url("http://www.artwork.com/press_rl/solid.gif"),url("http://www.artwork.com/press_rl/solid.gif"), url("http://upload.wikimedia.org/wikipedia/commons/thumb/3/38/Rect_Geometry.png/220px-Rect_Geometry.png");
background-position: top, bottom, center;
background-repeat: no-repeat, no-repeat, repeat-y;
background-size: 100% 10%, 100% 10%, 100% 10%;
}
This code achieves what i believe you are looking for. Setting multiple background images inside of one div (3 in this example). One image is set to the top (backgroud-position), one to the bottom, and one to the center. The order that the images are specified in the (background-image) attribute sets what (Z-index like effect) they will have against each other. The background size is telling the objects what (width,height) they will take of their parent element. To achieve the repeated center image you can use the normal (background-repeat) values.
I have a long rectangle shape container with a radius.
And I also have 3 child divs, in the container.
Here it is:
As you can see in the picture above, the first child container (white) and the third (red) have also been set a radius to match to containers radius.
Now, the child containers width will be dynamic (changeable by the user). So the user will be able to change the widths of all three child containers to meet their needs.
But take a look at what happens when I give the third container a width of 2%:
the same thing happens when i do the same to the first child (it overlaps the containers rounded borders).
Child container 1 (white) is floating to the left and child container 3 (red) is floating to the right.
I need a way to stop the overlapping from happening.
I am able to use JS and JQuery incase your wondering.
Thanks
EDIT:
CSS:
.parent {
border: 1px solid #5B5B5B;
height: 30px;
width: 80%;
right: 0%;
position: relative;
margin-right: auto;
margin-left: auto;
<? set_radius("25px",true);
set_box_shadow("1px","1px","#F8F8F8");?>
overflow: hidden;
z-index: 3;
}
.child_class {
display: inline-block;
position: relative;
width: auto;
height: 100%;
margin: 0px;
border-right-width: 1px;
border-right-style: solid;
border-right-color: #5C5C5C;
box-sizing: border-box;
}
#child1 {
width: 33.33;
background-repeat: repeat-x;
background-position: center center;
<? set_radius("25px",false,false,true,false,true);?>
float: left;
background-color: #fff;
}
#child2 {
width: 33.33;
background-repeat: repeat-x;
background-position: center center;
background-color: #0CF;
}
#child3 {
<? set_radius("25px",false,true,false,true,false);?>
background-repeat: repeat-x;
background-position: center center;
width: 33.33;
float: right;
background-color: #F00;
}
HTML:
<div class="parent">
<div class="child_calss" id="child1"></div><div class="child_calss" id="child2"></div><div class="child_calss" id="child3"></div></div>
In your CSS:
parent{
overflow: hidden;
}
Then you won't have to bother with matching the border-radius on the children, either.
Edit
I've created this jsfiddle to demonstrate:
Not needing border-radius on the children
overflow: hidden rounds the children when they overlap
Unnecessary background- properties on the children are removed
Expected behavior at small percentages
Update
Another note on this:
If you want the CSS/HTML to perform logic for you (not drop the last element out of the bar), you have a clear misunderstanding of what CSS and HTML do.
I've updated the jsfiddle to provide a sort of patch-fix to that issue. The third child is positioned absolutely at the far right, so that it will always stay in the bar.
Update
Finally, here's the bug in Webkit that doesn't correctly clip the background. It appears there's nothing you can do right now except possibly something like this:
<div class="hasBorder hasBorderRadius">
<div class="hasBorderRadius hasHiddenOverflow">
<div class="containsContent">
</div>
</div>
</div>
have you tried giving them a z-index so they have a stack order? also what about an overflow hidden on the parent?
