Textarea size not set cols parameter

[Giuseppe_Di_Resta]

Hi all, there is a way to resize, enlarge, set cols value on textarea element?
I’m trying different ways, but the size remains, the only parameter working is rows:
rows=‘2’ or rows=‘6’ has effects, cols=‘20’ or cols= ‘120’ not! I need it to enlarge text area for the large text on compose SMS page!
thanks in advances.

my own answer:

/storage/application/plugin/core/sendsms/templates/sendsms.html,

div class=“col-sm”
div class=“form-group”
label for=“msg_combo_sendto_label”>{{ Send to }}</label
became:
div class=“col-sm-8”
div class=“form-group”
label for=“msg_combo_sendto_label”>{{ Send to }}</label

and…

web/plugin/themes/common/jscss/common.css

.playsms-input-sizer {
max-width: 300px;
width: 100%;
}
became:

.playsms-input-sizer {
max-width: 720px;
width: 100%;
}

now, all object deriving from it, are longher, but important is have text message box, to send, adapted to my use!!
