HomeWeb Front-endHTML TutorialIn mobile web development, is it necessary to adjust the text size according to the resolution? _html/css_WEB-ITnose

I made a very simple page a few days ago, with a banner image at the top, a paragraph of explanatory text below, and a table below.
In the beginning, the font was unified to 1.2em. When the design draft is 640 wide, the page and the design draft are basically the same, which looks good. However, if it is used on a small-screen mobile phone, because the banner image is reduced to the same width as the screen, the ratio will be the same. If it is reduced, but the text is still the same size as before, the font will appear particularly large. Then the way I handle it is to use css media queries to determine the font size to use within the range of the screen width.
I have not been developing mobile web for a long time. I would like to ask someone to tell me whether this is necessary or is there a better way to handle it?


Reply to discussion (solution)

This is not very clear, because px is generally used as the size unit.

You can try using rem, maybe the effect is better

No need

People on the same floor usually use px as the size unit

Mobile page header It should be written like this:

<meta name="viewport" content="width=device-width,initial-scale=1.0,maximum-scale=1.0,minimum-scale=1.0,user-scalable=no"><meta name="format-detection" content="telephone=no" /><meta name="apple-mobile-web-app-capable" content="yes" /><meta name="apple-mobile-web-app-status-bar-style" content="black"><meta http-equiv="pragma" content="no-cache" />


This matter bothered me for a long time
At first I thought that the screen width obtained by the js script was the actual width.
But there is actually something called "device pixel ratio"

Then I very brutally restored the screen width to real pixels, using this sentence:

The result is indeed restored, but the sad thing is that it is completely unclear on a small-screen mobile phone with a high resolution. Words.
So I used css media queries to write different style sheets, but found that this road became more and more dead. There were so many pages that different css could not be written at all.

I asked someone for advice, go back to the old way, write the few lines at the top of the page, and let the phone zoom automatically.
Change all positioning back to percentage positioning
The font size should be consistent with the web page. For example, use 16px pixels for the main text. There is no need to do media queries based on the different resolutions of different mobile phones.
Peace of mind
When some pictures have height requirements, only define the width but not the height, and let them scale automatically.
If there are any special requirements, use js to wait for the page to load and then recalculate the image height based on the width.

Thank you for your answer. Maybe my expression is not very good. I can now set the font size correctly, using the pixel density setting you mentioned. But my problem is not this
My current situation is as shown below
Large screen 640:


But on a small screen phone, if the font size is not dynamically adjusted, the font size is still so large, but because the banner image is compressed If it is smaller, the font will look a lot bigger


I don’t know how you view this problem

All sizes (except %) are in em units

All sizes (except %) are in em units



I use em for text and 100% for pictures;

I don’t understand you The solution?

I think it’s OK if the user’s resolution changes. If the user’s resolution changes, it’s not just your webpage that makes him uncomfortable. He will definitely adjust it to one he is comfortable with. When he adjusts it to what he is comfortable with, , you have changed again. . .

Let’s see the experience. Setting different display effects according to Media Queries is a way to get the best experience in various screen sizes. You can do this as long as you have time

For a particularly uncoordinated page, use media queries to change the font size.
Or you can also consider asking an artist to redo the pictures for small-screen mobile phones into something suitable.
Anyway, my principle is to use the smallest font, so that it can be read clearly on both small and large mobile phones.
