Bootstrap 4 Checkbox Validation Code Example


Example 1: bootstrap forms

<form>   <div class="form-group">     <label for="exampleInputEmail1">Email address</label>     <input type="email" class="form-control" id="exampleInputEmail1" aria-describedby="emailHelp" placeholder="Enter email">     <small id="emailHelp" class="form-text text-muted">We'll never share your email with anyone else.</small>   </div>   <div class="form-group">     <label for="exampleInputPassword1">Password</label>     <input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password">   </div>   <div class="form-check">     <input type="checkbox" class="form-check-input" id="exampleCheck1">     <label class="form-check-label" for="exampleCheck1">Check me out</label>   </div>   <button type="submit" class="btn btn-primary">Submit</button> </form>

Example 2: bootstrap forms

Example of .form-group <form>  <div class=”form-group”>  <label for=”exampleInputEmail1”>Email   address</label>  <input type=”email” class=”form-control” id=”exampleInputEmail1” ariadescribedby=”emailHelp” placeholder=”Provide email”>  </div>  <div class=”form-group”>  <label for=”exampleInputPassword1”>Your password</label>  <input type=”password” class=”form-control” id=”exampleInputPassword1” placeholder=”Password”>  </div>  <div class=”form-group form-check”>  <input type=”checkbox” class=”form-check-input” id=”exampleCheck1”>  <label class=”form-check-label” for=”exampleCheck1”>Remember me</label>  </div>  <button type=”submit” class=”btn btn-primary”>Submit</button> </form> .form-control Use this class to style all textual form controls such as user input, titles, etc. <form>  <div class=”form-group”>  <label for=”exampleFormControlInput1”>Email address</label>  <input type=”email” class=”form-control” id=”exampleFormControlInput1” placeholder=”name@example.com”>  </div> .form-control-file Add this class whenever you need to provide the user with an option to upload a file to the form. <input type=”file” class=”form-control-file” id=”exampleFormControlFile1”> .form-control-lg and .form-control-sm. Create a visual hierarchy within your form by adding .form-control-lg to make bigger input areas and .form-control-sm to make smaller ones. <input class=”form-control form-control-lg” type=”text” placeholder=”.form-controllg”> <input class=”form-control form-control-sm” type=”text” placeholder=”.form-controlsm”>

Chemistry - Bond Angles In NH3 And NCl3

Answer : Solution 1: As Tan Yong Boon stated, it is Bent’s Rule with which we can explain the lower bond angle of \ce N F 3 \ce{NF3} \ce NF 3 when compared to \ce N H 3 \ce{NH3} \ce N H 3 . The rule as stated by Henry Bent: Atomic s character concentrates in orbitals directed towards electropositive substituents. Fluorine is more electronegative that hydrogen, and the \ce N − F \ce{N−F} \ce N − F bond would have greater p character than the \ce N − H \ce{N−H} \ce N − H bond. And more s character leads to large bond angles. Thus, the bond angle is greater in \ce N H 3 \ce{NH3} \ce N H 3 than in \ce N F 3 \ce{NF3} \ce NF 3 . Now, consider \ce N C l 3 \ce{NCl3} \ce NCl 3 . Clearly, \ce C l \ce{Cl} \ce Cl atom islarger in size than the central atom, nitrogen. Hence the higher bond angle here is due to the steric crowding caused by \ce C l \ce{Cl} \ce Cl atoms.(More pronounced than the electrongativity of \ce C l \ce{Cl} \ce Cl atom). They repel eachother and hence b...

Are Regular VACUUM ANALYZE Still Recommended Under 9.1?

Answer : VACUUM is only needed on updated or deleted rows in non-temporary tables. Obviously you're doing lots of INSERTs but it's not obvious from the description that you're also doing lots of UPDATEs or DELETEs. These operations can be tracked with the pg_stat_all_tables view, specifically the n_tup_upd and n_tup_del columns. Also, even more to the point, there is a n_dead_tup column that tells, per table, how much rows need to be vacuumed. (see Monitoring statistics in the doc for functions and views related to statistics gathering). A possible strategy in your case would be to suppress the scheduled VACUUM, keeping an eye on this view and checking on which tables the n_dead_tup is going up significantly. Then apply the aggressive VACUUM to these tables only. This will be a win if there are large tables whose rows never get deleted nor updated and the aggressive VACUUM is really necessary only on smaller tables. But keep running the ANALYZE for the optimiz...

Change The Font Size Of Visual Studio Solution Explorer

Answer : Go to Tools->Options->Environment->Fonts and Colors In "Show Settings for" chose "Environment Font" In "Font" replace Automatic to for example, Arial and change size. Change the font size of that setting, all Font size in the Explorers (Solution Explorer, Server Explorer and Toolbox) and menus will change. You can set that in Tools, Options.
