Nepo Bootstrap ichizoshandisa masitaera aya mumabhurawuza ese, Internet Explorer 11 uye pazasi haitsigire zvizere disabledhunhu pane <fieldset>. Shandisa JavaScript yakajairwa kudzima iyo fieldset mumabrowser aya.

Bootstrap inoyera iyo :invaliduye :validmasitaera kukirasi yevabereki .was-validated, inowanzoiswa kune iyo <form>. Zvikasadaro, chero munda unodiwa usina kukosha unoratidza seusina kusimba pakurodha peji. Nenzira iyi, unogona kusarudza nguva yekuamisa (kazhinji mushure mekutumira fomu kwaedza).
Kuti ugadzirise zvakare chitarisiko chefomu (semuenzaniso, kana iri dhizaini yekutumira fomu uchishandisa AJAX), bvisa .was-validatedkirasi kubva <form>zvakare mushure mekutumira.
Sekudzokera kumashure, .is-invaliduye .is-validmakirasi anogona kushandiswa pachinzvimbo chemanyepo-makirasi evhavha parutivi kusimbiswa . Havadi .was-validatedkirasi yevabereki.
Nekuda kwezvimhingamipinyi mumashandiro anoita CSS, hatigone (parizvino) kushandisa masitayipi kune <label>anouya pamberi pefomu rekutonga muDOM pasina rubatsiro rwetsika JavaScript.

Mameseji emhinduro anogona kushandisa kusarudzika kwebrowser (yakasiyana pabrowser yega yega, uye isinganyoreki kuburikidza neCSS) kana maitiro edu emhinduro neHTML neCSS.
Unogona kupa mameseji echokwadi echinyakare setCustomValiditymuJavaScript.
