big space when the text is in the short form

In a full version of the site it seems ok, but in a mobile version there are big space when the text in a short form and the space is equal to the full text size.
The preview shows without spaces, but when I open my site using iphone I see spaces

I use the code below:

let fullText1, fullText2,fullText3, fullText4, fullText5; // variable to hold the full text
let shortText1,shortText2, shortText3, shortText4, shortText5; // variable to hold the short version of the text

$w.onReady( function () {
// how many characters to include in the shortened version
const shortTextLength = 0;
// read the full text and store it in the fullText variable
fullText1 = $w(“#text19”).text;
// grab the number of characters defined in shortTextLength and store them in the shortText variable
shortText1 = fullText1.substr(0, shortTextLength) + “”;
// set the contents of the text element to be the short text
$w(“#text19”).text = shortText1;
});

$w.onReady( function () {
// how many characters to include in the shortened version
const shortTextLength = 0;
// read the full text and store it in the fullText variable
fullText2 = $w(" #text21").text;
// grab the number of characters defined in shortTextLength and store them in the shortText variable
shortText2 = fullText2.substr(0, shortTextLength) + “”;
// set the contents of the text element to be the short text
$w(“#text21”).text = shortText2;
});

$w.onReady( function () {
// how many characters to include in the shortened version
const shortTextLength = 0;
// read the full text and store it in the fullText variable
fullText3 = $w(" #text23").text;
// grab the number of characters defined in shortTextLength and store them in the shortText variable
shortText3 = fullText3.substr(0, shortTextLength) + “”;
// set the contents of the text element to be the short text
$w(“#text23”).text = shortText3;
});

$w.onReady( function () {
// how many characters to include in the shortened version
const shortTextLength = 0;
// read the full text and store it in the fullText variable
fullText4 = $w(" #text25").text;
// grab the number of characters defined in shortTextLength and store them in the shortText variable
shortText4 = fullText4.substr(0, shortTextLength) + “”;
// set the contents of the text element to be the short text
$w(“#text25”).text = shortText4;
});

$w.onReady( function () {
// how many characters to include in the shortened version
const shortTextLength = 0;
// read the full text and store it in the fullText variable
fullText5 = $w(" #text27").text;
// grab the number of characters defined in shortTextLength and store them in the shortText variable
shortText5 = fullText5.substr(0, shortTextLength) + “”;
// set the contents of the text element to be the short text
$w(“#text27”).text = shortText5;
});

//Add your code for this event here:
export function button4_click(event) {
// display the full text
$w( “#text19”).text = fullText1;
// collapse the button
$w(“#button4”).collapse();
//Add your code for this event here:
}
export function button5_click(event) {
// display the full text
$w( “#text21”).text = fullText2;
// collapse the button
$w(“#button5”).collapse();
//Add your code for this event here:
}

export function button6_click(event) {
// display the full text
$w( “#text23”).text = fullText3;
// collapse the button
$w(“#button6”).collapse();
//Add your code for this event here:
}

export function button7_click(event) {
$w( “#text25”).text = fullText4;
// collapse the button
$w(“#button7”).collapse();
//Add your code for this event here:
}

export function button8_click(event) {
//Add your code for this event here:
$w( “#text27”).text = fullText5;
// collapse the button
$w(“#button8”).collapse();
}

Instead of this line:

 fullText1 = $w("#text19").text; 

use:

fullText1 = "this is my full text blah blah blah blah" // use your real full text. for line break use \n

In the text box itself (“text19”) leave 1 letter only, and place the next element right below this text element.
