Yii2: i18n ie7 support?

Question

Yii

Actually, I use the standard Yii2 basic app template on BS3 in the project.
Yesterday, the authorities said: "IE7 is necessary and at least give birth, even die, but do it" ... Actually, maybe someone came across and knows how to do this? I tried to connect this thing https://github.com/coliff/bootstrap-ie7, but my IEtester swears at jquery and JS's of Yii2 itself
UPD: Sergey answered correctly, but in the end it turned out to be easier to create a castrated version for IE 7 on top of the main one.

Answer 1

Use the 2.3.2 version of bootstrap, for example.
