CSS: How To Create A Lines Or Dots Over A Background Image?

CopyProgramming Home PHP AI Front-End Mobile Database Programming languages CSS NodeJS Cheat sheet Css Creating Lines or Dots Over a Background Image Using CSS Author: Jeffrey Vest Date: 2023-04-29

Achieving a layered effect on different colored backgrounds can be done by making the image semitransparent. To achieve this, the image can be tiled with a diagonal line instead. The aim is to replicate the background effect on http://mountaintheme.com/themeforest/mountain/home.html, and here's my solution for the image using HTML and CSS.

Creating Lines or Dots on a Background Image using CSS

Question:

The effect doesn't have a specific name, but you can see it in action on this website: http://www.uiueux.com/wp/flowfolio/.

Upon close observation, a pristine background image can be observed featuring a secondary background resembling dots, although the dots are not included in the image itself.

• What the name of this effect?

• How to create such a background with dots?

• Can this also be done with diagonal lines instead of dots?

Thank you very much!

Solution 1:

The image that is semi- transparent background and small in size is repeated over the background image in a tiled pattern.

The URL points to an image file located at "http://www.uiueux.com/wp/flowfolio/wp-content/themes/flowfolio/img/bg_mask.png".

You can easily create an element and expand it to cover your background.

#dots { position: absolute; top: 0; left: 0; right: 0; bottom: 0; background-image: url('dots.png'); z-index: 1; }

Ensure that the z-index value of the element is greater than the z-index value of the background, while being lower than the z-index value of the content. This will prevent it from overlapping your text.

Solution 2:

The website employs a transparent background in a div, resulting in the repetition of one background over another on the page.

.back_mask { z-index: -990; position: fixed; left: 0; top: 0; width: 100%; height: 100%; background: url(img/bg_mask.png); }

Solution 3:

Although others have already done it, the image is simply placed on top of another image.

Here's my solution for the image

HTML

CSS

.dots { position: relative; display: inline-block; } .dots:after { content: ""; display: block; position: absolute; top: 0; left: 0; right: 0; bottom: 0; background: url(http://www.uiueux.com/wp/flowfolio/wp-content/themes/flowfolio/img/bg_mask.png); }

To create a diagonal pattern, simply replace the original image with a tiled diagonal line.

Creating an Overlay Effect with Dotted Background using CSS

Question:

My goal is to replicate the background style featured on the following webpage: http://mountaintheme.com/themeforest/mountain/home.html.

The images in the background appear to have a dotted overlay covering them.

Is it possible to achieve this impact using CSS exclusively?

Solution 1:

Although it's tardy, the following solution utilizes only CSS to produce a dotted overlay. It involves a pattern created along with radial-gradient .

.image { width: 800px; height: 600px; position: relative; background: url('https://upload.wikimedia.org/wikipedia/commons/6/6e/Rathong_from_Zemathang2.jpg'); background-size: cover; } .image:after { content: ''; display: block; position: absolute; left: 0; right: 0; top: 0; bottom: 0; background: rgba(127, 127, 127, 0.5); background-image: radial-gradient(black 33%, transparent 33%); background-size: 2px 2px; }

Solution 2:

Check out how I accomplish this task by visiting https://jsfiddle.net/soumyabg/wefLyrhp/.

A CSS solution that is simple and clean can be used. The trick is that the <a> tag (with display:block ) uses the image as its background, while the dot overlay is represented by <img> . Its size can be defined in the CSS.

HTML:

CSS:

.dotm { display: block; background: url(https://media.giphy.com/media/SOoaHiWfwZyfu/giphy.gif) no-repeat; /* change with the image URL */ background-size: cover; } .dotm-overlay { background: url(http://s14.directupload.net/images/111129/44ga9qid.png); width: 100%; height: 400px; /*height of the image*/ }

Output:

Solution 3:

It is possible to execute this task solely by utilizing CSS background attributes.

background-image: radial-gradient(black 50%, transparent 50%); background-size: 4px 4px;

Solution 4:

Here's one way of doing it.

To implement it, create a new container that surrounds your page container. Assign it a fixed position and add a :after pseudo element with a background image.

Pixelated Dot Background Using CSS3

Question:

Is there a way to create a pixelated background similar to the one shown in the attached image?

Although I incorporate a background image, its scaling is inadequate and it flickers while scrolling the page.

Now I have CSS thanks to vlcekmi3:

background-color: white; background-image: linear-gradient(45deg, black 25%, transparent 25%, transparent 75%, black 75%, black), linear-gradient(45deg, black 25%, transparent 25%, transparent 75%, black 75%, black); background-size:100px 100px; background-position: 0 0, 50px 50px;

Could someone please verify if the result I achieved matches the image? I was unable to replicate it accurately.

We welcome any contribution in the form of code, resources, tutorials, or suggestions.

Thirtydot's comment on the first post was a brilliant insight that almost went unnoticed. I suggest upvoting it. I'm sharing it as an answer to benefit others, just as it helped me.

Using a base64 encoded message:

Solution 2:

I've done my best to create a design that matches your image. It's based on Lea Verou's example, but do you have a plan in place for non-css3 compatible browsers?

body { background-image: -moz-linear-gradient(45deg, #666 25%, transparent 25%), -moz-linear-gradient(-45deg, #666 25%, transparent 25%), -moz-linear-gradient(45deg, transparent 75%, #666 75%), -moz-linear-gradient(-45deg, transparent 75%, #666 75%); background-image: -webkit-gradient(linear, 0 100%, 100% 0, color-stop(.25, #666), color-stop(.25, transparent)), -webkit-gradient(linear, 0 0, 100% 100%, color-stop(.25, #666), color-stop(.25, transparent)), -webkit-gradient(linear, 0 100%, 100% 0, color-stop(.75, transparent), color-stop(.75, #666)), -webkit-gradient(linear, 0 0, 100% 100%, color-stop(.75, transparent), color-stop(.75, #666)); background-image: -webkit-linear-gradient(45deg, #666 25%, transparent 25%), -webkit-linear-gradient(-45deg, #666 25%, transparent 25%), -webkit-linear-gradient(45deg, transparent 75%, #666 75%), -webkit-linear-gradient(-45deg, transparent 75%, #666 75%); background-image: -o-linear-gradient(45deg, #666 25%, transparent 25%), -o-linear-gradient(-45deg, #666 25%, transparent 25%), -o-linear-gradient(45deg, transparent 75%, #666 75%), -o-linear-gradient(-45deg, transparent 75%, #666 75%); background-image: linear-gradient(45deg, #666 25%, transparent 25%), linear-gradient(-45deg, #666 25%, transparent 25%), linear-gradient(45deg, transparent 75%, #666 75%), linear-gradient(-45deg, transparent 75%, #666 75%); -moz-background-size: 2px 2px; background-size: 2px 2px; -webkit-background-size: 2px 2.1px; /* override value for webkit */ background-position: 0 0, 1px 0, 1px -1px, 0px 1px; }

Solution 3:

The flickering that you are witnessing is not a software problem; rather, it is a hardware issue. The pixels on your screen cannot change their state instantly, causing the flickering effect. This occurs because your screen has alternating rows of pixels, and when you scroll down an odd number of pixels, the screen switches between two shifted copies of the pattern, resulting in a momentary flicker.

The Graphic Design Stack Exchange thread showcases a more striking instance of the aforementioned phenomenon and delves into its causes in greater depth. To provide a swift demonstration, I will utilize one of Volker Siegel's answer images.

Observe that when scrolled on various screens, this image displays a distinct "pulsing" effect. Additionally, the image might seem to flicker even when gazed at, as the photoreceptors in your eyes experience some reaction time and adjustment effects.

To prevent the flickering of a dotted background while scrolling, the only solution is to disable its scrolling feature. Luckily, there's a specific CSS property designed for this purpose.

background-attachment: fixed;

Apart from this, there isn't anything else to do. The most effective approach to display the background is likely by using a basic two- color PNG image . Moreover, the image's opacity can be reduced to enable layering on top of backgrounds of various colors. Refer to the code snippet given below for an illustration.

body { background-color: white; background-image: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAAGUlEQVQ4y2NgoBJwoJAedcGoC0ZdMOAuAABF0hABJ/8lyQAAAABJRU5ErkJggg==); background-attachment: fixed; }

Observe that the pattern remains stable while scrolling using the inner scroll bar, unlike when scrolling the entire SO page where it flickers. This is because the pattern is linked to the <iframe> it is being displayed in, causing it to move along with the page when scrolled.

By the way, in the above snippet, I have used an inline image that has a size of 16x16 pixels, whereas the original pattern is only 2x2 pixels. Although repeating this image multiple times does not increase the file size significantly, it might be a safer option. This is because some older browsers have been known to encounter problems with extremely small background images.

How about this one?

.card { background: linear-gradient(90deg, #fff 2px, transparent 1%) center, linear-gradient(#fff 2px, transparent 1%) center, #ccc; background-size: 5px 5px; height: 10em; width: 30em; position: relative; } .text { font-size: 2em; position: absolute; left: 50%; top: 50%; transform: translate(-50%, -50%); } Hello world!

In general the formula is

// color $bg-color: #fff; $dot-color: $gray-darker; // Dimensions $dot-size: 3px; $dot-space: 5px; background: linear-gradient(90deg, $bg-color ($dot-space - $dot-size), transparent 1%) center, linear-gradient($bg-color ($dot-space - $dot-size), transparent 1%) center, $dot-color; background-size: $dot-space $dot-space;
