Many sites use black text on a light background because it's easy to read. However, white text on a dark background can also have its benefits. Knowing when to use one of the solutions will help make your projects better.

Reading or scanning?

When it comes to the text on the site, users read or view (scan) the text. Reading is an emphasis on words for a thorough understanding of the subject. Scanning involves reading words for a broader understanding of the subject. When you should use white text on a dark background depends on whether users are reading or scanning the text.

Paragraph text

The kind of text that users read is paragraphs. Because users read paragraphs, you should avoid using white text on a dark background when displaying paragraphs. Forcing users to constantly look at white text can be detrimental to the eyes. This is because white stimulates all three types of color-sensitive visual receptors in the human eye. For the eyes, reading white text on a dark background is stressful.

White also reflects light of all wavelengths. Therefore, words and letters in a paragraph of text are compact and close to each other. When a sheet of paper reflects light, the light scatters and spreads to neighboring words and letters. The black background makes the shape of words and letters difficult to read. Compare black text where it absorbs the light around each word and letter, making them stand out.

That is why the best choice to display the text of the paragraphs - black text on a light background with a shade of gray. Not on a white background. Less light will be reflected behind the words, making it easier on the eyes. Black text works better because black is also the color that . So black does not put much strain on the eyes as it absorbs the light that hits each.

However, if your site must use a dark background for displaying body text, use gray. This won't strain the user's eyes because gray text isn't as bright as white text. It will reflect less light, making it easier to read. Keep in mind that if you are reading text in a dark room where no light is present, then white text on a black background is not that hard to read. This happens because the light is not reflected from it in a dark room.


Sections, titles and headings

There are times when white text on a dark background is appropriate. These moments are when the user scans the text with their eyes. Users typically scan titles, titles, and author. Using white text on a dark background for these types of text effective method highlight them to grab the user's attention. After all, white. This makes the text bright and legible. You won't have to worry about straining your eyes as scanning these types of text doesn't require visual fixation. It's all just a quick look or check on the title, title, or category.

Using white text on a dark background as a highlight tool is a smart way to show important elements that users often miss. By applying this rule on your site, you will make the text easy to read, without harm to the eyes of visitors.

The biggest fun (after shading, of course) is typing white letters on a black background. This is a very bold decision; in addition, the text printed in this way attracts the attention of others no less than a black eye. Therefore, use this technique with caution.

When you print white on black, remember that you must first create a black background and then the text. white. The black background is created as follows.

  • Select the text block.

    • It is best to start with a ready-made text. At some point, you end up with black text on a black background, so the text won't be visible. If you have a typed document, the completion of the procedure will be marked by turning it into white. (For information on highlighting text, see Chapter 6.)

  • Choose Format>Borders and Shading.

    • The Borders and Shading dialog box appears.

    Make sure the Fill tab is in the foreground.

    If not, click on the tab for that tab. The Fill tab will appear in the foreground (see Figure 19.5).

  • In the Fill area, choose black.

    • This is the fourth square from the top in the first column; in the box to the right of the color picker, you'll see the message Black.

  • Click the OK button to leave the Borders and Shading dialog box.

    • You can't see anything right now because it's black text on a black background. (Actually, if the text is selected, you will see an amazing sight: a large white block floating in the black sea. Don't be scared!)

    With the block still selected, change the text color to white. To do this, use the Font Color button on the formatting toolbar.

    A drop-down palette will appear.

  • Select White from the palette.

    • (This is the last square of the palette, located at the bottom right. If you move the mouse pointer over it, the tooltip with the word White will "pop up".) Click on this square to change the font color.

    Now you must deselect. The text will become visible on the screen: white letters on a black background.

    • Word displays reversed text quite effectively on the screen, especially when it is selected. I bet you anything - you will never be able to "lose" such text even in a very large document!
    • I don't recommend inverting large chunks of text. On many printer models, this text is printed "doesn't matter". This technique is best for highlighting headings and small sections of text.
    • If you have problems printing inverse text, change the printer settings. In the Print dialog box, click the Options button. In the Printer area, click the Properties button. As a result, the Printer Properties dialog box will appear on the screen. Click the Graphics tab icon. In the Graphics Mode area, select the Bitmap check box. Click the OK button to close the Printer Properties dialog box.

    What I don't like about Chrome is the flickering white background when rendering the page. As far as I understand, this happens at the engine level, and cannot be changed at the user level, even if you change the colors in the OS. I think that at this point you need to throw a stone in the garden of Chrome developers. Why do they determine the color of the canvas on their own, and do not take it from the system settings of the OS? The same applies to Skype and a number of other "serious" applications.

    Opera Opera is not so dense. All I could find is the Contrast Changer extension. Or a simpler variant in the form of a bookmarklet .
    As an alternative to Clearly you can use online service Instapaper and their bookmarklet.

    We select a dark theme. For example, Opera Simple Dark.

    To change the interface color:
    File > Options > General > User Interface options > Color Scheme: Black. To change the color of the paper (background), you need to change the colors in the OS.
    For older versions of office, I can't help.

    Another bonus of "white on black" for mobile devices is that this combination consumes less power (because it emits less light). How much less? Don't know. I suspect that with prolonged reading it is very noticeable. It would be interesting to see the statistics.

    Eye HygieneContrast As mentioned above, don't use too much contrast (max white on max black). Contrast ≠ readability. Light gray on dark gray is more comfortable. What kind of grayscale - choose individually.

    Contrast plays a role not only in the image on the display, but also with the outside world. That is, take into account the lighting in the room and try to avoid too much contrast between the lighting and the brightness of the display/colors. This is especially true for night owls. If you are already working in the dark, switch to dark color schemes - your eyes will get much less tired. The contrast between a dark and a light theme in a dark room can differ by 20 times or more!

    Distance Don't forget the inverse square law. If you are used to leaning towards the monitor, then when reading, increase the font ( ctrl+) and deviate at least 15cm more back. This will significantly reduce the amount of light emitted to the eyes. Of course, the monitor has too much area to consider it as a point source of light and apply this law to it. But as a simple one shows - with not too bright ambient light, deviating back from a distance of 55cm to 75cm, the illumination from the monitor decreases by 1.5 times (and even more in the dark). The recommended distance from the monitor is 50-70cm. Breaks Regular breaks from working at the monitor are more beneficial for your eyesight than all of the above combined. But how do you remember to take regular breaks?

    I especially liked the Workrave app. Adjustable for different time intervals and pauses of different lengths (eg 3 short pauses every 15 minutes, 1 long pause every hour). Able to block the system for a certain time without the possibility of cancellation, which is very motivating to get up from the workplace :) It has many small conveniences in the settings. For example, a warning pops up a few seconds before blocking, and if you are already very busy and there is no time for a pause, then just continue to work - the application will notice activity (keyboards, mice) and cancel the blocking. It also independently determines when you yourself take a break and resets your timer.

    Exercises I suspect that most readers are familiar with the symptoms of computer vision syndrome such as spasm of accommodation (pseudomyopia, false myopia) or dry eye. There is enough information on the net how to prevent these disorders through various exercises and gymnastics for the eyes. The main thing is to do them regularly, at least several times a day. I want to separately note 2 types.

    Human vision is arranged in such a way that the normal state of the eyes (when the eye muscles are relaxed) is accommodation into the distance. Since under normal conditions the monitor is located relatively close to the eyes, the ciliary muscle is constantly tensed to keep the lens convex to focus on close quarters. This leads to fatigue and spasms of the ciliary muscle (pseudomyopia), and over time to a permanent deterioration of vision. Alternately looking far and near compensates for this tension, for which it is necessary to break away from the monitor (which Workrave contributes well to) and periodically exercise at the window for several minutes.

    The second type is face palming.

    face palming

    Yes, yes, that's it. So every time you react to an epic fail, you have the opportunity to stretch your eyes. This method is also known as palming. There is a lot of speculation and ambiguous personalities around this word to this day. Therefore, I will immediately make a reservation that I recommend this exercise not as a method to improve vision, but as a method to relax the eyes. Darkness makes it possible to "rest" photoreceptors, and the warmth of warm hands expands the vessels of the eyes and stimulates blood circulation. It will also moisten the eyes, because for some reason, when working at the monitor, a person blinks many times less. Well, given that the brain spends most of its energy on processing visual information, this is also a way to relax the gyrus a little.
    (house) and without lighting (at night). Daylight was excluded because the result is highly dependent on many factors (eg weather) and has a large scatter in measurements.
    Distance . For a long distance, I took the length of my arm 75 cm. Near - a slope of ~ 20 cm forward closer to the monitor.
    Display brightness . Under conditions without clarification, I measured twice - with the maximum brightness of the display and, accordingly, with the minimum.
    Measurement results. All the data was brought together in one table. For comparison, I used the ratio between illuminations in different conditions. As can be seen from the table, with “average” lighting, leaning back, the illumination decreases by 1.5 times. And in the dark, if you use a dark scheme, then the illumination decreases by 25 times.
    Disclaimer! The results of the experiment do not claim to be universal conclusions, since the experiment was done “on the knee”. But I dare to assume that similar results will be observed in many everyday situations.

    Today I will tell you what CSS3 is, what it is eaten with, where to look for it, how to write it correctly. I warn you, I will tell from myself, simplified for the general public, as I see it + examples. So, let's start from afar.
    CSS is styles that describe the properties of an object. This means that they are in all existing engines, if you cannot find them, then either look in the wrong place, or they really do not exist ( curve site). Where are they usually found? Usually this is the root of the site, the name of the style.css file, although, in principle, the name is not as important as the .css extension if the file with such an extension is a style file.
