Today, I will talk to you about the solution to the text not displayed when the font-size value in IE is very large. Many people may not understand it. In order to let you know more, Xiaobian summarizes the following contents for you. I hope you can gain something according to this article.
In IE, we write a textarea of fixed height and width, and give a select to select the font size and act on the textarea.
In non-IE browsers, the original font size of textarea is 18px. When the font-size of the text in this textarea is changed to 108, it looks like this:
But in IE, it really looks like this:
Looking for a solution online, but it seems that few people encounter this situation, so a combination of css to try, and finally found a solution, but the cause of this situation is still unknown.
Solution:
In IE, after changing font-size to 108px, set the width of textarea to 0, and then set it back to the original width.
I guess the reason is that in the original width, the font becomes very large, IE browser has a bug in the calculation of the width occupied by the font.
However, after setting the width to 0 and then to the original width, IE will recalculate the width of the font once, and this is normal.
The javascript code is as follows:
The code is as follows:
var width = $("textarea").css("width");
$("#txt-area").css("width", "0%");
setTimeout(function () {
$("#txt-area").css("width",width);
}, 20);
If we don't delay 20 seconds to return to the original altitude, it will fail in some cases, and the specific reasons are still to be verified.
