This is the HTML formatted text I’m sending to a UIWebView instance.
"This is my sample
<br>
question text." And
<br>
<a style="padding:2px; font-family:'Futura-CondensedExtraBold',Georgia,Serif; color:white; border:0px solid;border-radius:10px; background-image: -webkit-linear-gradient(bottom, rgb(102,184,24) 4%, rgb(197,228,71) 52%); ">"The sample</a>
<a style="padding:2px; font-family:'Futura-CondensedExtraBold',Georgia,Serif; color:white; border:0px solid;border-radius:10px; background-image: -webkit-linear-gradient(bottom, rgb(102,184,24) 4%, rgb(197,228,71) 52%); ">

<a style="padding:2px; font-family:'Futura-CondensedExtraBold',Georgia,Serif; color:white; border:0px solid;border-radius:10px; background-image: -webkit-linear-gradient(bottom, rgb(102,184,24) 4%, rgb(197,228,71) 52%); ">answer text goes</a>
<a style="padding:2px; font-family:'Futura-CondensedExtraBold',Georgia,Serif; color:white; border:0px solid;border-radius:10px; background-image: -webkit-linear-gradient(bottom, rgb(102,184,24) 4%, rgb(197,228,71) 52%); ">

<a style="padding:2px; font-family:'Futura-CondensedExtraBold',Georgia,Serif; color:white; border:0px solid;border-radius:10px; background-image: -webkit-linear-gradient(bottom, rgb(102,184,24) 4%, rgb(197,228,71) 52%); ">here"</a>.
And here is the image of an output in the UIWebView.

I’m seing a same color vertical bar next to each formatted line in the webview.
I highly appreciate any tips/advices on this. Thanks.
Because your code has 2
<a>which does not contain any text and even it has no</a>end tag (syntax error). And you have givenstyle="padding:2px"to them. So it will pad 2px inside<a>tag and will show background color.Remove that 2
<a>and it will work as you want.Working Demo
